To highlight a few of the reasons you might want to use LCEL: + +[**First-class streaming support**](/docs/expression_language/streaming) +When you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens. + +[**Async support**](/docs/expression_language/interface) +Any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](/docs/langsmith) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server. + +[**Optimized parallel execution**](/docs/expression_language/primitives/parallel) +Whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency. + +[**Retries and fallbacks**](/docs/guides/productionization/fallbacks) +Configure retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. We’re currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost. + +[**Access intermediate results**](/docs/expression_language/interface#async-stream-events-beta) +For more complex chains it’s often very useful to access the results of intermediate steps even before the final output is produced. This can be used to let end-users know something is happening, or even just to debug your chain. You can stream intermediate results, and it’s available on every [LangServe](/docs/langserve) server. + +[**Input and output schemas**](/docs/expression_language/interface#input-schema) +Input and output schemas give every LCEL chain Pydantic and JSONSchema schemas inferred from the structure of your chain. This can be used for validation of inputs and outputs, and is an integral part of LangServe. + +[**Seamless LangSmith tracing**](/docs/langsmith) +As your chains get more and more complex, it becomes increasingly important to understand what exactly is happening at every step. +With LCEL, **all** steps are automatically logged to [LangSmith](/docs/langsmith/) for maximum observability and debuggability. + +[**Seamless LangServe deployment**](/docs/langserve) +Any chain created with LCEL can be easily deployed using [LangServe](/docs/langserve). + +### Interface + +To make it as easy as possible to create custom chains, we've implemented a ["Runnable"](https://api.python.langchain.com/en/stable/runnables/langchain_core.runnables.base.Runnable.html#langchain_core.runnables.base.Runnable) protocol. Many LangChain components implement the `Runnable` protocol, including chat models, LLMs, output parsers, retrievers, prompt templates, and more. There are also several useful primitives for working with runnables, which you can read about [in this section](/docs/expression_language/primitives). + +This is a standard interface, which makes it easy to define custom chains as well as invoke them in a standard way. +The standard interface includes: + +- [`stream`](#stream): stream back chunks of the response +- [`invoke`](#invoke): call the chain on an input +- [`batch`](#batch): call the chain on a list of inputs + +These also have corresponding async methods that should be used with [asyncio](https://docs.python.org/3/library/asyncio.html) `await` syntax for concurrency: + +- [`astream`](#async-stream): stream back chunks of the response async +- [`ainvoke`](#async-invoke): call the chain on an input async +- [`abatch`](#async-batch): call the chain on a list of inputs async +- [`astream_log`](#async-stream-intermediate-steps): stream back intermediate steps as they happen, in addition to the final response +- [`astream_events`](#async-stream-events): **beta** stream events as they happen in the chain (introduced in `langchain-core` 0.1.14) + +The **input type** and **output type** varies by component: + +| Component | Input Type | Output Type | +| --- | --- | --- | +| Prompt | Dictionary | PromptValue | +| ChatModel | Single string, list of chat messages or a PromptValue | ChatMessage | +| LLM | Single string, list of chat messages or a PromptValue | String | +| OutputParser | The output of an LLM or ChatModel | Depends on the parser | +| Retriever | Single string | List of Documents | +| Tool | Single string or dictionary, depending on the tool | Depends on the tool | + + +All runnables expose input and output **schemas** to inspect the inputs and outputs: +- [`input_schema`](#input-schema): an input Pydantic model auto-generated from the structure of the Runnable +- [`output_schema`](#output-schema): an output Pydantic model auto-generated from the structure of the Runnable + +### Primitives + +The following are all different build in runnables or runnable methods. + +#### The Pipe Operator + +One key advantage of the `Runnable` interface is that any two runnables can be "chained" together into sequences. The output of the previous runnable's `.invoke()` call is passed as input to the next runnable. This can be done using the pipe operator (`|`), or the more explicit `.pipe()` method, which does the same thing. The resulting `RunnableSequence` is itself a runnable, which means it can be invoked, streamed, or piped just like any other runnable. + +For example: + +```python +from langchain_anthropic import ChatAnthropic +from langchain_core.output_parsers import StrOutputParser +from langchain_core.prompts import ChatPromptTemplate + +prompt = ChatPromptTemplate.from_template("tell me a joke about {topic}") +model = ChatAnthropic(model_name="claude-3-haiku-20240307") + +chain = prompt | model | StrOutputParser() +``` +Prompts and models are both runnable, and the output type from the prompt call is the same as the input type of the chat model, so we can chain them together. We can then invoke the resulting sequence like any other runnable: + +```python +chain.invoke({"topic": "bears"}) +``` + +**Coercion** + +We can even combine this chain with more runnables to create another chain. This may involve some input/output formatting using other types of runnables, depending on the required inputs and outputs of the chain components. + +For example, let's say we wanted to compose the joke generating chain with another chain that evaluates whether or not the generated joke was funny. + +We would need to be careful with how we format the input into the next chain. In the below example, the dict in the chain is automatically parsed and converted into a [`RunnableParallel`](/docs/expression_language/primitives/parallel), which runs all of its values in parallel and returns a dict with the results. + +This happens to be the same format the next prompt template expects. Here it is in action: + +```python +from langchain_core.output_parsers import StrOutputParser + +analysis_prompt = ChatPromptTemplate.from_template("is this a funny joke? {joke}") + +composed_chain = {"joke": chain} | analysis_prompt | model | StrOutputParser() + +composed_chain.invoke({"topic": "bears"}) +``` \ No newline at end of file diff --git a/docs/docs/expression_language/interface.ipynb b/docs/docs/expression_language/interface.ipynb index 88485abd50eb6..7c045b13602cd 100644 --- a/docs/docs/expression_language/interface.ipynb +++ b/docs/docs/expression_language/interface.ipynb @@ -1401,7 +1401,7 @@ "name": "python", "nbconvert_exporter": "python", "pygments_lexer": "ipython3", - "version": "3.11.4" + "version": "3.10.1" } }, "nbformat": 4, diff --git a/docs/docs/expression_language/primitives/passthrough.ipynb b/docs/docs/expression_language/primitives/passthrough.ipynb index b21d04317ac30..86c231c247def 100644 --- a/docs/docs/expression_language/primitives/passthrough.ipynb +++ b/docs/docs/expression_language/primitives/passthrough.ipynb @@ -153,7 +153,7 @@ "name": "python", "nbconvert_exporter": "python", "pygments_lexer": "ipython3", - "version": "3.11.6" + "version": "3.10.1" } }, "nbformat": 4, diff --git a/docs/docs/expression_language/primitives/sequence.ipynb b/docs/docs/expression_language/primitives/sequence.ipynb index 8aec2b496ceba..9aebcd439b6d7 100644 --- a/docs/docs/expression_language/primitives/sequence.ipynb +++ b/docs/docs/expression_language/primitives/sequence.ipynb @@ -221,7 +221,7 @@ ], "metadata": { "kernelspec": { - "display_name": "Python 3", + "display_name": "Python 3 (ipykernel)", "language": "python", "name": "python3" }, @@ -235,7 +235,7 @@ "name": "python", "nbconvert_exporter": "python", "pygments_lexer": "ipython3", - "version": "3.10.5" + "version": "3.10.1" } }, "nbformat": 4, From b34ef122655a50a5a91694fec3e831659eac86d4 Mon Sep 17 00:00:00 2001 From: jacoblee93 Date: Sat, 13 Apr 2024 10:47:45 -0700 Subject: [PATCH 004/109] Adds component concepts --- docs/docs/concepts.mdx | 57 ++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 55 insertions(+), 2 deletions(-) diff --git a/docs/docs/concepts.mdx b/docs/docs/concepts.mdx index 2451f09a05261..4c043fb6d015e 100644 --- a/docs/docs/concepts.mdx +++ b/docs/docs/concepts.mdx @@ -38,9 +38,9 @@ pip install langchain ``` If you want to work with specific integrations, you will need to install them separately. -See [here](integrations) for a list of integrations and how to install them. +See [here](/docs/integrations) for a list of integrations and how to install them. -For working with LangSmith, you will need to set up a LangSmith developer account [here](smith.langchain.com) and get an API key. +For working with LangSmith, you will need to set up a LangSmith developer account [here](https://smith.langchain.com) and get an API key.

Useful when you are using LLMs to generate structured data, or to normalize output from chat models and LLMs. Some implementations can handle streamed output from models and "transform" individual chunks into a different format. -### [Document loaders](/docs/modules/data_connection/document_loaders/) +Many common use-cases in LangChain follow this pattern of formatting inputs with a `prompt template`, calling a `model`, and +formatting outputs with an `output parser`. + +![Flowchart illustrating the Model I/O process with steps Format, Predict, and Parse, showing the transformation from input variables to structured output.](/img/model_io.jpg "Model Input/Output Process Diagram") + +### Retrieval + +Retrieval of data is a key component of providing LLMs with user-specific data that is not part of the model's training set, commonly referred to as **Retrieval-Augmented Generation** (RAG). +In this process, external data is retrieved and then passed to the LLM during the generation step. + +#### [Document loaders](/docs/modules/data_connection/document_loaders/) Load data from a source as text and associated metadata. Useful for retrieval-augmented generation (RAG). Implementations include loaders for [PDF file content](/docs/modules/data_connection/document_loaders/pdf/) and [GitHub repos](/docs/integrations/document_loaders/github/#load-github-file-content). -### [Text splitters](/docs/modules/data_connection/document_transformers/) +#### [Text splitters](/docs/modules/data_connection/document_transformers/) Prepare and transform loaded data into formats more suitable for a language model to use as context when performing RAG. Implementations include [generic text splitters](/docs/modules/data_connection/document_transformers/recursive_text_splitter/) and [more specialized ones](/docs/modules/data_connection/document_transformers/code_splitter/) for code in various languages. -### [Embedding models](/docs/modules/data_connection/text_embedding/) +#### [Embedding models](/docs/modules/data_connection/text_embedding/) Models that create a vector representation of a piece of text. Useful for semantic search. Implementations include [`mistral-embed`](/docs/integrations/text_embedding/mistralai/) and OpenAI's [`text-embedding-3-large`](/docs/integrations/text_embedding/openai/). -### [Vectorstores](/docs/modules/data_connection/vectorstores/) +#### [Vectorstores](/docs/modules/data_connection/vectorstores/) A specialized database that stores embedded data and performs semantic search over vector embeddings. Implementations include [PGVector](/docs/integrations/vectorstores/pgvector/) and [LanceDB](/docs/integrations/vectorstores/lancedb/). -### [Retrievers](/docs/modules/data_connection/retrievers/) +#### [Retrievers](/docs/modules/data_connection/retrievers/) An interface that returns documents given an unstructured query. More general than a vector store, since a retriever does not need to be able to store documents, only return (or retrieve) them. Retrievers can be created from vectorstores, but are also broad enough to include [Wikipedia search](/docs/integrations/retrievers/wikipedia/) and [Amazon Kendra](/docs/integrations/retrievers/amazon_kendra_retriever/). -### [Tools](/docs/modules/tools/) +### Composition + +This section contains higher-level components that combine other arbitrary systems (e.g. external APIs and services) and/or LangChain primitives together. +A good primer for this section would be reading the sections on [LangChain Expression Language](/docs/concepts/#langchain-expression-language) and becoming familiar with constructing sequences via piping and the various primitives offered. + +#### [Tools](/docs/modules/tools/) An interface that an agent, chain, or bare language model can use to interact with the world. Tools can fetch data from various sources for the model to use as context, but can also perform actions. Implementations include [web search](/docs/integrations/tools/tavily_search/) and [Twilio SMS](/docs/integrations/tools/twilio/). -### [Agents](/docs/modules/agents/) +#### [Agents](/docs/modules/agents/) Interfaces that allow a language model to choose an action to take at a given step. When run in a loop using an executor, they can autonomously solve abstract, multi-step problems. Implementations can rely on specific model functionality like [tool calling](/docs/modules/agents/agent_types/tool_calling/) for performance or use a more generalized prompt-based approach like [ReAct](/docs/modules/agents/agent_types/react/). -### [Chains](/docs/modules/chains/) +#### [Chains](/docs/modules/chains/) Sequences of calls, whether to an LLM, a tool, or a data preprocessing step. These are primarily composed using LangChain Expression Language, but also include some more opaque object-oriented classes. diff --git a/docs/docs/how_to_guides.md b/docs/docs/how_to_guides.md index 2cba86a54fccc..11e5520e585a7 100644 --- a/docs/docs/how_to_guides.md +++ b/docs/docs/how_to_guides.md @@ -12,29 +12,29 @@ However, these guides will help you quickly accomplish common tasks. - How to see what is going on inside your LLM application - How to test your LLM application - How to deploy your LLM application -- ### LCEL -- [How to chain runnables](expression_language/primitives/sequence.ipynb) -- [How to run two runnables in parallel](expression_language/primitives/parallel.ipynb) -- [How to attach runtime arguments to a runnable](expression_language/primitives/binding.ipynb) +- [How to chain runnables](/docs/expression_language/primitives/sequence) +- [How to run two runnables in parallel](/docs/expression_language/primitives/parallel/) +- [How to attach runtime arguments to a runnable](/docs/expression_language/primitives/binding/) - ## Components + ### Prompts -- [How to use example selectors](modules/model_io/prompts/example_selectors/index.ipynb) -- [How to use few shot examples in chat models](modules/model_io/prompts/few_shot_examples_chat.ipynb) +- [How to use example selectors](/docs/modules/model_io/prompts/example_selectors/) +- [How to use few shot examples in chat models](/docs/modules/model_io/prompts/few_shot_examples_chat/) ## Use Cases ### Q&A with RAG -- [How to add chat history](use_cases/question_answering/chat_history.ipynb) -- [How to stream](use_cases/question_answering/streaming.ipynb) -- [How to return sources](use_cases/question_answering/sources.ipynb) -- [How to return citations](use_cases/question_answering/citations.ipynb) +- [How to add chat history](/docs/use_cases/question_answering/chat_history/) +- [How to stream](/docs/use_cases/question_answering/streaming/) +- [How to return sources](/docs/use_cases/question_answering/sources/) +- [How to return citations](/docs/use_cases/question_answering/citations/) ### Extraction -- [How to use reference examples](use_cases/extraction/how_to/examples.ipynb) -- [How to handle long text](use_cases/extraction/how_to/handle_long_text.ipynb) \ No newline at end of file +- [How to use reference examples](/docs/use_cases/extraction/how_to/examples/) +- [How to handle long text](/docs/use_cases/extraction/how_to/handle_long_text/) diff --git a/docs/docs/tutorials.md b/docs/docs/tutorials.md index 0ba120200e7b3..68395871d8e78 100644 --- a/docs/docs/tutorials.md +++ b/docs/docs/tutorials.md @@ -4,18 +4,18 @@ New to LangChain?

The simplest example is you may want to split a long document into smaller chunks that can fit into your model's context window. LangChain has a number of built-in document transformers that make it easy to split, combine, filter, and otherwise manipulate documents. + +When you want to deal with long pieces of text, it is necessary to split up that text into chunks. As simple as this sounds, there is a lot of potential complexity here. Ideally, you want to keep the semantically related pieces of text together. What "semantically related" means could depend on the type of text. This notebook showcases several ways to do that. + +At a high level, text splitters work as following: + +1. Split the text up into small, semantically meaningful chunks (often sentences). +2. Start combining these small chunks into a larger chunk until you reach a certain size (as measured by some function). +3. Once you reach that size, make that chunk its own piece of text and then start creating a new chunk of text with some overlap (to keep context between chunks). + +That means there are two different axes along which you can customize your text splitter: + +1.

This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space. + +The base Embeddings class in LangChain provides two methods: one for embedding documents and one for embedding a query.

With approximately 366 species and 113 genera, they occur from Alaska to Tierra del Fuego, but most species are found in Central and South America. As of 2024, 21 hummingbird species are listed as endangered or critically endangered, with numerous species declining in population.Hummingbirds have varied specialized characteristics to enable rapid, maneuverable flight: exceptional metabolic capacity, adaptations to high altitude, sensitive visual and communication abilities, and long-distance migration in some species. Among all birds, male hummingbirds have the widest diversity of plumage color, particularly in blues, greens, and purples. Hummingbirds are the smallest mature birds, measuring 7.5–13 cm (3–5 in) in length. The smallest is the 5 cm (2.0 in) bee hummingbird, which weighs less than 2.0 g (0.07 oz), and the largest is the 23 cm (9 in) giant hummingbird, weighing 18–24 grams (0.63–0.85 oz). Noted for long beaks, hummingbirds are specialized for feeding on flower nectar, but all species also consume small insects.\n", + "They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to other birds and humans. They hover at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species to 80 per second in small hummingbirds.\n", + "Hummingbirds have the highest mass-specific metabolic rate of any homeothermic animal. To conserve energy when food is scarce and at night when not foraging, they can enter torpor, a state similar to hibernation, and slow their metabolic rate to 1⁄15 of its normal rate. While most hummingbirds do not migrate, the rufous hummingbird has one of the longest migrations among birds, traveling twice per year between Alaska and Mexico, a distance of about 3,900 miles (6,300 km).\n", + "Hummingbirds split from their sister group, the swifts and treeswifts, around 42 million years ago.

Used guide a model's response, helping it understand the context and generate relevant and coherent language-based output. + +### [Example Selectors](/docs/modules/model_io/prompts/example_selectors) +Select examples to include in the prompt as few shot examples. There are generally a few ways of doing this, the two main ones being randomly or by semantic similarity. + +### [Chat models](/docs/modules/model_io/chat/) +Language models that uses chat messages as inputs and returns chat messages as outputs (as opposed to using plain text). +Implementations include [GPT-4](/docs/integrations/chat/openai/) and [Claude 3](/docs/integrations/chat/anthropic/). + +### Message types + +Some language models take a list of messages as input and return a message. There are a few different types of messages. All messages have a `role` and a `content` property. The `role` describes WHO is saying the message. LangChain has different message classes for different roles. The `content` property describes the content of the message. This can be a few different things: + +- A string (most models deal this type of content) +- A List of dictionaries (this is used for multi-modal input, where the dictionary contains information about that input type and that input location) + +In addition, messages have an `additional_kwargs` property. This is where additional information about messages can be passed. This is largely used for input parameters that are *provider specific* and not general. The best known example of this is `function_call` from OpenAI. + +#### HumanMessage + +This represents a message from the user. Generally consists only of content. + +#### AIMessage + +This represents a message from the model. This may have `additional_kwargs` in it - for example `tool_calls` if using OpenAI tool calling. + +#### SystemMessage + +This represents a system message, which tells the model how to behave. This generally only consists of content. Not every model supports this. + +#### FunctionMessage + +This represents the result of a function call. In addition to `role` and `content`, this message has a `name` parameter which conveys the name of the function that was called to produce this result. + +#### ToolMessage + +This represents the result of a tool call. This is distinct from a FunctionMessage in order to match OpenAI's `function` and `tool` message types. In addition to `role` and `content`, this message has a `tool_call_id` parameter which conveys the id of the call to the tool that was called to produce this result. + +### [LLMs](/docs/modules/model_io/llms/) +Language models that takes a string as input and returns a string. +Implementations include [GPT-3](/docs/integrations/llms/openai/). + +### [Output parsers](/docs/modules/model_io/output_parsers/) +Responsible for taking the output of a model and transforming it to a more suitable format for downstream tasks. +Useful when you are using LLMs to generate structured data, or to normalize output from chat models and LLMs. +Some implementations can handle streamed output from models and "transform" individual chunks into a different format. + +Many common use-cases in LangChain follow this pattern of formatting inputs with a `prompt template`, calling a `model`, and +formatting outputs with an `output parser`. + +![Flowchart illustrating the Model I/O process with steps Format, Predict, and Parse, showing the transformation from input variables to structured output.](/img/model_io.jpg "Model Input/Output Process Diagram") + +## Retrieval + +Retrieval of data is a key component of providing LLMs with user-specific data that is not part of the model's training set, commonly referred to as **Retrieval-Augmented Generation** (RAG). +In this process, external data is retrieved and then passed to the LLM during the generation step. + +### [Document loaders](/docs/modules/data_connection/document_loaders/) +Load data from a source as text and associated metadata. +Useful for retrieval-augmented generation (RAG). +Implementations include loaders for [PDF file content](/docs/modules/data_connection/document_loaders/pdf/) and [GitHub repos](/docs/integrations/document_loaders/github/#load-github-file-content). + +### [Text splitters](/docs/modules/data_connection/document_transformers/) +Once you've loaded documents, you'll often want to transform them to better suit your application. The simplest example is you may want to split a long document into smaller chunks that can fit into your model's context window. LangChain has a number of built-in document transformers that make it easy to split, combine, filter, and otherwise manipulate documents. + +When you want to deal with long pieces of text, it is necessary to split up that text into chunks. As simple as this sounds, there is a lot of potential complexity here. Ideally, you want to keep the semantically related pieces of text together. What "semantically related" means could depend on the type of text. This notebook showcases several ways to do that. + +At a high level, text splitters work as following: + +1. Split the text up into small, semantically meaningful chunks (often sentences). +2. Start combining these small chunks into a larger chunk until you reach a certain size (as measured by some function). +3. Once you reach that size, make that chunk its own piece of text and then start creating a new chunk of text with some overlap (to keep context between chunks). + +That means there are two different axes along which you can customize your text splitter: + +1. How the text is split +2. How the chunk size is measured + +Implementations include [generic text splitters](/docs/modules/data_connection/document_transformers/recursive_text_splitter/) +and [more specialized ones](/docs/modules/data_connection/document_transformers/code_splitter/) for code in various languages. + +### [Embedding models](/docs/modules/data_connection/text_embedding/) +The Embeddings class is a class designed for interfacing with text embedding models. There are lots of embedding model providers (OpenAI, Cohere, Hugging Face, etc) - this class is designed to provide a standard interface for all of them. + +Embeddings create a vector representation of a piece of text. This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space. + +The base Embeddings class in LangChain provides two methods: one for embedding documents and one for embedding a query. The former takes as input multiple texts, while the latter takes a single text. The reason for having these as two separate methods is that some embedding providers have different embedding methods for documents (to be searched over) vs queries (the search query itself). + +Implementations include [`mistral-embed`](/docs/integrations/text_embedding/mistralai/) and OpenAI's [`text-embedding-3-large`](/docs/integrations/text_embedding/openai/). + +### [Vectorstores](/docs/modules/data_connection/vectorstores/) +One of the most common ways to store and search over unstructured data is to embed it and store the resulting embedding vectors, +and then at query time to embed the unstructured query and retrieve the embedding vectors that are 'most similar' to the embedded query. +A vector store takes care of storing embedded data and performing vector search for you. + + +Implementations include [PGVector](/docs/integrations/vectorstores/pgvector/) and [LanceDB](/docs/integrations/vectorstores/lancedb/). + +### [Retrievers](/docs/modules/data_connection/retrievers/) +A retriever is an interface that returns documents given an unstructured query. +It is more general than a vector store. +A retriever does not need to be able to store documents, only to return (or retrieve) them. +Retrievers can be created from vectorstores, but are also broad enough to include [Wikipedia search](/docs/integrations/retrievers/wikipedia/) and [Amazon Kendra](/docs/integrations/retrievers/amazon_kendra_retriever/). + +Retrievers accept a string query as input and return a list of Document's as output. + +## Composition + +This section contains higher-level components that combine other arbitrary systems (e.g. external APIs and services) and/or LangChain primitives together. +A good primer for this section would be reading the sections on [LangChain Expression Language](/docs/concepts/#langchain-expression-language) and becoming familiar with constructing sequences via piping and the various primitives offered. + +### [Tools](/docs/modules/tools/) +Tools are interfaces that an agent, chain, or LLM can use to interact with the world. +They combine a few things: + +1. The name of the tool +2. A description of what the tool is +3. JSON schema of what the inputs to the tool are +4. The function to call +5. Whether the result of a tool should be returned directly to the user + +It is useful to have all this information because this information can be used to build action-taking systems! The name, description, and JSON schema can be used to prompt the LLM so it knows how to specify what action to take, and then the function to call is equivalent to taking that action. + +The simpler the input to a tool is, the easier it is for an LLM to be able to use it. +Many agents will only work with tools that have a single string input. +For a list of agent types and which ones work with more complicated inputs, please see [this documentation](/docs/modules/agents/agent_types) + +Importantly, the name, description, and JSON schema (if used) are all used in the prompt. Therefore, it is really important that they are clear and describe exactly how the tool should be used. You may need to change the default name, description, or JSON schema if the LLM is not understanding how to use the tool. +Implementations include [web search](/docs/integrations/tools/tavily_search/) and [Twilio SMS](/docs/integrations/tools/twilio/). + +### Toolkits + +Toolkits are collections of tools that are designed to be used together for specific tasks. They have convenient loading methods. +For a complete list of available ready-made toolkits, visit [Integrations](/docs/integrations/toolkits/). + +All Toolkits expose a `get_tools` method which returns a list of tools. +You can therefore do: + +```python +# Initialize a toolkit +toolkit = ExampleTookit(...) + +# Get list of tools +tools = toolkit.get_tools() + +# Create agent +agent = create_agent_method(llm, tools, prompt) +``` + +### [Agents](/docs/modules/agents/) +Interfaces that allow a language model to choose an action to take at a given step. +When run in a loop using an executor, they can autonomously solve abstract, multi-step problems. +Implementations can rely on specific model functionality like [tool calling](/docs/modules/agents/agent_types/tool_calling/) for performance +or use a more generalized prompt-based approach like [ReAct](/docs/modules/agents/agent_types/react/). + +### [Chains](/docs/modules/chains/) +Sequences of calls, whether to an LLM, a tool, or a data preprocessing step. These are primarily composed using LangChain Expression Language, +but also include some more opaque object-oriented classes. + +## LangChain Expression Language + +LangChain Expression Language, or LCEL, is a declarative way to easily compose chains together. +LCEL was designed from day 1 to **support putting prototypes in production, with no code changes**, from the simplest “prompt + LLM” chain to the most complex chains (we’ve seen folks successfully run LCEL chains with 100s of steps in production). To highlight a few of the reasons you might want to use LCEL: + +[**First-class streaming support**](/docs/expression_language/streaming) +When you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens. + +[**Async support**](/docs/expression_language/interface) +Any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](/docs/langsmith) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server. + +[**Optimized parallel execution**](/docs/expression_language/primitives/parallel) +Whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency. + +[**Retries and fallbacks**](/docs/guides/productionization/fallbacks) +Configure retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. We’re currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost. + +[**Access intermediate results**](/docs/expression_language/interface#async-stream-events-beta) +For more complex chains it’s often very useful to access the results of intermediate steps even before the final output is produced. This can be used to let end-users know something is happening, or even just to debug your chain. You can stream intermediate results, and it’s available on every [LangServe](/docs/langserve) server. + +[**Input and output schemas**](/docs/expression_language/interface#input-schema) +Input and output schemas give every LCEL chain Pydantic and JSONSchema schemas inferred from the structure of your chain. This can be used for validation of inputs and outputs, and is an integral part of LangServe. + +[**Seamless LangSmith tracing**](/docs/langsmith) +As your chains get more and more complex, it becomes increasingly important to understand what exactly is happening at every step. +With LCEL, **all** steps are automatically logged to [LangSmith](/docs/langsmith/) for maximum observability and debuggability. + +[**Seamless LangServe deployment**](/docs/langserve) +Any chain created with LCEL can be easily deployed using [LangServe](/docs/langserve). + +### Interface + +To make it as easy as possible to create custom chains, we've implemented a ["Runnable"](https://api.python.langchain.com/en/stable/runnables/langchain_core.runnables.base.Runnable.html#langchain_core.runnables.base.Runnable) protocol. Many LangChain components implement the `Runnable` protocol, including chat models, LLMs, output parsers, retrievers, prompt templates, and more. There are also several useful primitives for working with runnables, which you can read about [in this section](/docs/expression_language/primitives). + +This is a standard interface, which makes it easy to define custom chains as well as invoke them in a standard way. +The standard interface includes: + +- [`stream`](#stream): stream back chunks of the response +- [`invoke`](#invoke): call the chain on an input +- [`batch`](#batch): call the chain on a list of inputs + +These also have corresponding async methods that should be used with [asyncio](https://docs.python.org/3/library/asyncio.html) `await` syntax for concurrency: + +- [`astream`](#async-stream): stream back chunks of the response async +- [`ainvoke`](#async-invoke): call the chain on an input async +- [`abatch`](#async-batch): call the chain on a list of inputs async +- [`astream_log`](#async-stream-intermediate-steps): stream back intermediate steps as they happen, in addition to the final response +- [`astream_events`](#async-stream-events): **beta** stream events as they happen in the chain (introduced in `langchain-core` 0.1.14) + +The **input type** and **output type** varies by component: + +| Component | Input Type | Output Type | +| --- | --- | --- | +| Prompt | Dictionary | PromptValue | +| ChatModel | Single string, list of chat messages or a PromptValue | ChatMessage | +| LLM | Single string, list of chat messages or a PromptValue | String | +| OutputParser | The output of an LLM or ChatModel | Depends on the parser | +| Retriever | Single string | List of Documents | +| Tool | Single string or dictionary, depending on the tool | Depends on the tool | + + +All runnables expose input and output **schemas** to inspect the inputs and outputs: +- [`input_schema`](#input-schema): an input Pydantic model auto-generated from the structure of the Runnable +- [`output_schema`](#output-schema): an output Pydantic model auto-generated from the structure of the Runnable + +### Primitives + +The following are all different build in runnables or runnable methods. + +#### The Pipe Operator + +One key advantage of the `Runnable` interface is that any two runnables can be "chained" together into sequences. The output of the previous runnable's `.invoke()` call is passed as input to the next runnable. This can be done using the pipe operator (`|`), or the more explicit `.pipe()` method, which does the same thing. The resulting `RunnableSequence` is itself a runnable, which means it can be invoked, streamed, or piped just like any other runnable. + +For example: + +```python +from langchain_anthropic import ChatAnthropic +from langchain_core.output_parsers import StrOutputParser +from langchain_core.prompts import ChatPromptTemplate + +prompt = ChatPromptTemplate.from_template("tell me a joke about {topic}") +model = ChatAnthropic(model_name="claude-3-haiku-20240307") + +chain = prompt | model | StrOutputParser() +``` +Prompts and models are both runnable, and the output type from the prompt call is the same as the input type of the chat model, so we can chain them together. We can then invoke the resulting sequence like any other runnable: + +```python +chain.invoke({"topic": "bears"}) +``` + +**Coercion** + +We can even combine this chain with more runnables to create another chain. This may involve some input/output formatting using other types of runnables, depending on the required inputs and outputs of the chain components. + +For example, let's say we wanted to compose the joke generating chain with another chain that evaluates whether or not the generated joke was funny. + +We would need to be careful with how we format the input into the next chain. In the below example, the dict in the chain is automatically parsed and converted into a [`RunnableParallel`](/docs/expression_language/primitives/parallel), which runs all of its values in parallel and returns a dict with the results. + +This happens to be the same format the next prompt template expects. Here it is in action: + +```python +from langchain_core.output_parsers import StrOutputParser + +analysis_prompt = ChatPromptTemplate.from_template("is this a funny joke? {joke}") + +composed_chain = {"joke": chain} | analysis_prompt | model | StrOutputParser() + +composed_chain.invoke({"topic": "bears"}) +``` \ No newline at end of file diff --git a/docs/versioned_docs/version-0.2.x/contributing/code.mdx b/docs/versioned_docs/version-0.2.x/contributing/code.mdx new file mode 100644 index 0000000000000..7825831763563 --- /dev/null +++ b/docs/versioned_docs/version-0.2.x/contributing/code.mdx @@ -0,0 +1,250 @@ +--- +sidebar_position: 1 +--- +# Contribute Code + +To contribute to this project, please follow the ["fork and pull request"](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow. +Please do not try to push directly to this repo unless you are a maintainer. + +Please follow the checked-in pull request template when opening pull requests.

Add the dependency to the main group as an optional dependency + ```bash + poetry add --optional [package_name] + ``` +2. Open pyproject.toml and add the dependency to the `extended_testing` extra +3. Relock the poetry file to update the extra. + ```bash + poetry lock --no-update + ``` +4. Add a unit test that the very least attempts to import the new code. Ideally, the unit +test makes use of lightweight fixtures to test the logic of the code. +5.

It is helpful to think in these terms +when contributing new documentation: + +### Getting started + +The [getting started section](/docs/get_started/introduction) includes a high-level introduction to LangChain, a quickstart that +tours LangChain's various features, and logistical instructions around installation and project setup. + +It contains elements of **How-to guides** and **Explanations**. + +### Use cases + +[Use cases](/docs/use_cases/) are guides that are meant to show how to use LangChain to accomplish a specific task (RAG, information extraction, etc.). +The quickstarts should be good entrypoints for first-time LangChain developers who prefer to learn by getting something practical prototyped, +then taking the pieces apart retrospectively. These should mirror what LangChain is good at. + +The quickstart pages here should fit the **How-to guide** category, with the other pages intended to be **Explanations** of more +in-depth concepts and strategies that accompany the main happy paths. + +:::note +The below sections are listed roughly in order of increasing level of abstraction. +::: + +### Expression Language + +[LangChain Expression Language (LCEL)](/docs/expression_language/) is the fundamental way that most LangChain components fit together, and this section is designed to teach +developers how to use it to build with LangChain's primitives effectively. + +This section should contains **Tutorials** that teach how to stream and use LCEL primitives for more abstract tasks, **Explanations** of specific behaviors, +and some **References** for how to use different methods in the Runnable interface. + +### Components + +The [components section](/docs/modules) covers concepts one level of abstraction higher than LCEL. +Abstract base classes like `BaseChatModel` and `BaseRetriever` should be covered here, as well as core implementations of these base classes, +such as `ChatPromptTemplate` and `RecursiveCharacterTextSplitter`. Customization guides belong here too. + +This section should contain mostly conceptual **Tutorials**, **References**, and **Explanations** of the components they cover. + +:::note +As a general rule of thumb, everything covered in the `Expression Language` and `Components` sections (with the exception of the `Composition` section of components) should +cover only components that exist in `langchain_core`. +::: + +### Integrations + +The [integrations](/docs/integrations/platforms/) are specific implementations of components. These often involve third-party APIs and services. +If this is the case, as a general rule, these are maintained by the third-party partner. + +This section should contain mostly **Explanations** and **References**, though the actual content here is more flexible than other sections and more at the +discretion of the third-party provider. + +:::note +Concepts covered in `Integrations` should generally exist in `langchain_community` or specific partner packages. +::: + +### Guides and Ecosystem + +The [Guides](/docs/guides) and [Ecosystem](/docs/langsmith/) sections should contain guides that address higher-level problems than the sections above. +This includes, but is not limited to, considerations around productionization and development workflows. + +These should contain mostly **How-to guides**, **Explanations**, and **Tutorials**. + +### API references + +LangChain's API references.

Let's walk through the intended path: + +- The developer lands on https://python.langchain.com, and reads through the introduction and the diagram. +- If they are just curious, they may be drawn to the [Quickstart](/docs/get_started/quickstart) to get a high-level tour of what LangChain contains. +- If they have a specific task in mind that they want to accomplish, they will be drawn to the Use-Case section. The use-case should provide a good, concrete hook that shows the value LangChain can provide them and be a good entrypoint to the framework. +- They can then move to learn more about the fundamentals of LangChain through the Expression Language sections. +- Next, they can learn about LangChain's various components and integrations. +- Finally, they can get additional knowledge through the Guides. + +This is only an ideal of course - sections will inevitably reference lower or higher-level concepts that are documented in other sections. + +## Guidelines + +Here are some other guidelines you should think about when writing and organizing documentation. + +### Linking to other sections + +Because sections of the docs do not exist in a vacuum, it is important to link to other sections as often as possible +to allow a developer to learn more about an unfamiliar topic inline. + +This includes linking to the API references as well as conceptual sections! + +### Conciseness + +In general, take a less-is-more approach. If a section with a good explanation of a concept already exists, you should link to it rather than +re-explain it, unless the concept you are documenting presents some new wrinkle. + +Be concise, including in code samples. + +### General style + +- Use active voice and present tense whenever possible. +- Use examples and code snippets to illustrate concepts and usage. +- Use appropriate header levels (`#`, `##`, `###`, etc.) to organize the content hierarchically. +- Use bullet points and numbered lists to break down information into easily digestible chunks. +- Use tables (especially for **Reference** sections) and diagrams often to present information visually. +- Include the table of contents for longer documentation pages to help readers navigate the content, but hide it for shorter pages. diff --git a/docs/versioned_docs/version-0.2.x/contributing/documentation/technical_logistics.mdx b/docs/versioned_docs/version-0.2.x/contributing/documentation/technical_logistics.mdx new file mode 100644 index 0000000000000..4dbb0204df1a9 --- /dev/null +++ b/docs/versioned_docs/version-0.2.x/contributing/documentation/technical_logistics.mdx @@ -0,0 +1,171 @@ +# Technical logistics + +LangChain documentation consists of two components: + +1.

This means that all functions, classes, and methods should have a docstring that explains what they do, what the arguments are, and what the return value is.

The cons mentioned above can be mitigated or overcome with proper training, support, and a commitment to continuous improvement. It is also important to note that not all cons may be applicable to every organization or project.\\n\\nFor example, while Scrum may be complex initially, with proper training and guidance, teams can quickly grasp the concepts and practices. The lack of predictability can be mitigated by implementing techniques such as velocity tracking and release planning. The limited documentation can be addressed by maintaining a balance between lightweight documentation and clear communication among team members. The dependency on team collaboration can be improved through effective communication channels and regular team-building activities.\\n\\nScrum can be scaled and adapted to larger projects by using frameworks like Scrum of Scrums or LeSS (Large Scale Scrum). Concerns about speed versus quality can be addressed by incorporating quality assurance practices, such as continuous integration and automated testing, into the Scrum process. Scope creep can be managed by having a well-defined and prioritized product backlog, and a strong product owner can be developed through training and mentorship.\\n\\nResistance to change can be overcome by providing proper education and communication to stakeholders and involving them in the decision-making process. Ultimately, the cons of Scrum can be seen as opportunities for growth and improvement, and with the right mindset and support, they can be effectively managed.\\n\\nIn conclusion, while Scrum may have its challenges and potential cons, the benefits and advantages it offers in terms of collaboration, flexibility, adaptability, transparency, and customer satisfaction make it a widely adopted and successful project management framework.

The officeholder leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the number of presidencies and the number of individuals who have served as president. The incumbent president is Joe Biden.The presidency of William Henry Harrison, who died 31 days after taking office in 1841, was the shortest in American history. Franklin D. Roosevelt served the longest, over twelve years, before dying early in his fourth term in 1945. He is the only U.S. president to have served more than two terms. Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once.Four presidents died in office of natural causes (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy), and one resigned (Richard Nixon, facing impeachment and removal from office). John Tyler was the first vice president to assume the presidency during a presidential term, and set the precedent that a vice president who does so becomes the fully functioning president with his presidency.Throughout most of its history, American politics has been dominated by political parties. The Constitution is silent on the issue of political parties, and at the time it came into force in 1789, no organized parties existed. Soon after the 1st Congress convened, political factions began rallying around dominant Washington administration officials, such as Alexander Hamilton and Thomas Jefferson. Concerned about the capacity of political parties to destroy the fragile unity holding the nation together, Washington remained unaffiliated with any political faction or party throughout his eight-year presidency. He was, and remains, the only U.S. president never affiliated with a political party.\n", + "\n", + "Page: List of presidents of the United States by age\n", + "Summary: In this list of presidents of the United States by age, the first table charts the age of each president of the United States at the time of presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Where the president is still living, their lifespan and post-presidency timespan are calculated up to January 25, 2024.\n", + "\n", + "Page: List of vice presidents of the United States\n", + "Summary: There have been 49 vice presidents of the United States since the office was created in 1789. Originally, the vice president was the person who received the second-most votes for president in the Electoral College. But after the election of 1800 produced a tie between Thomas Jefferson and Aaron Burr, requiring the House of Representatives to choose between them, lawmakers acted to prevent such a situation from recurring. The Twelfth Amendment was added to the Constitution in 1804, creating the current system where electors cast a separate ballot for the vice presidency.The vice president is the first person in the presidential line of succession—that is, they assume the presidency if the president dies, resigns, or is impeached and removed from office. Nine vice presidents have ascended to the presidency in this way: eight (John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, and Lyndon B. Johnson) through the president's death and one (Gerald Ford) through the president's resignation. The vice president also serves as the president of the Senate and may choose to cast a tie-breaking vote on decisions made by the Senate. Vice presidents have exercised this latter power to varying extents over the years.Before adoption of the Twenty-fifth Amendment in 1967, an intra-term vacancy in the office of the vice president could not be filled until the next post-election inauguration. Several such vacancies occurred: seven vice presidents died, one resigned and eight succeeded to the presidency. This amendment allowed for a vacancy to be filled through appointment by the president and confirmation by both chambers of the Congress. Since its ratification, the vice presidency has been vacant twice (both in the context of scandals surrounding the Nixon administration) and was filled both times through this process, namely in 1973 following Spiro Agnew's resignation, and again in 1974 after Gerald Ford succeeded to the presidency. The amendment also established a procedure whereby a vice president may, if the president is unable to discharge the powers and duties of the office, temporarily assume the powers and duties of the office as acting president. Three vice presidents have briefly acted as president under the 25th Amendment: George H. W. Bush on July 13, 1985; Dick Cheney on June 29, 2002, and on July 21, 2007; and Kamala Harris on November 19, 2021.\n", + "The persons who have served as vice president were born in or primarily affiliated with 27 states plus the District of Columbia. New York has produced the most of any state as eight have been born there and three others considered it their home state. Most vice presidents have been in their 50s or 60s and had political experience before assuming the office. Two vice presidents—George Clinton and John C. Calhoun—served under more than one president. Ill with tuberculosis and recovering in Cuba on Inauguration Day in 1853, William R. King, by an Act of Congress, was allowed to take the oath outside the United States. He is the only vice president to take his oath of office in a foreign country.\n", + "\n", + "Page: List of presidents of the United States by net worth\n", + "Summary: The list of presidents of the United States by net worth at peak varies greatly. Debt and depreciation often means that presidents' net worth is less than $0 at the time of death. Most presidents before 1845 were extremely wealthy, especially Andrew Jackson and George Washington. \t \n", + "Presidents since 1929, when Herbert Hoover took office, have generally been wealthier than presidents of the late nineteenth and early twentieth centuries; with the exception of Harry S. Truman, all presidents since this time have been millionaires. These presidents have often received income from autobiographies and other writing. Except for Franklin D. Roosevelt and John F. Kennedy (both of whom died while in office), all presidents beginning with Calvin Coolidge have written autobiographies. In addition, many presidents—including Bill Clinton—have earned considerable income from public speaking after leaving office.The richest president in history may be Donald Trump. However, his net worth is not precisely known because the Trump Organization is privately held.Truman was among the poorest U.S. presidents, with a net worth considerably less than $1 million. His financial situation contributed to the doubling of the presidential salary to $100,000 in 1949. In addition, the presidential pension was created in 1958 when Truman was again experiencing financial difficulties. Harry and Bess Truman received the first Medicare cards in 1966 via the Social Security Act of 1965.\n", + "\n", + "Page: List of presidents of the United States by home state\n", + "Summary: These lists give the states of primary affiliation and of birth for each president of the United States.\u001b[0m\u001b[32;1m\u001b[1;3m\n", + "Invoking: `Wikipedia` with `Joe Biden`\n", + "\n", + "\n", + "\u001b[0m\u001b[36;1m\u001b[1;3mPage: Joe Biden\n", + "Summary: Joseph Robinette Biden Jr. ( BY-dən; born November 20, 1942) is an American politician who is the 46th and current president of the United States.

He graduated from the University of Delaware before earning his law degree from Syracuse University. He was elected to the New Castle County Council in 1970 and to the U.S. Senate in 1972. As a senator, Biden drafted and led the effort to pass the Violent Crime Control and Law Enforcement Act and the Violence Against Women Act. He also oversaw six U.S. Supreme Court confirmation hearings, including the contentious hearings for Robert Bork and Clarence Thomas. Biden ran unsuccessfully for the Democratic presidential nomination in 1988 and 2008. In 2008, Obama chose Biden as his running mate, and he was a close counselor to Obama during his two terms as vice president. In the 2020 presidential election, Biden and his running mate, Kamala Harris, defeated incumbents Donald Trump and Mike Pence. He became the oldest president in U.S. history, and the first to have a female vice president.\n", + "As president, Biden signed the American Rescue Plan Act in response to the COVID-19 pandemic and subsequent recession. He signed bipartisan bills on infrastructure and manufacturing. He proposed the Build Back Better Act, which failed in Congress, but aspects of which were incorporated into the Inflation Reduction Act that he signed into law in 2022. Biden appointed Ketanji Brown Jackson to the Supreme Court. He worked with congressional Republicans to resolve the 2023 United States debt-ceiling crisis by negotiating a deal to raise the debt ceiling. In foreign policy, Biden restored America's membership in the Paris Agreement. He oversaw the complete withdrawal of U.S. troops from Afghanistan that ended the war in Afghanistan, during which the Afghan government collapsed and the Taliban seized control. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia and authorizing civilian and military aid to Ukraine. During the Israel–Hamas war, Biden announced military support for Israel, and condemned the actions of Hamas and other Palestinian militants as terrorism. In April 2023, Biden announced his candidacy for the Democratic nomination in the 2024 presidential election.\n", + "\n", + "Page: Presidency of Joe Biden\n", + "Summary: Joe Biden's tenure as the 46th president of the United States began with his inauguration on January 20, 2021. Biden, a Democrat from Delaware who previously served as vice president for two terms under president Barack Obama, took office following his victory in the 2020 presidential election over Republican incumbent president Donald Trump. Biden won the presidency with a popular vote of over 81 million, the highest number of votes cast for a single United States presidential candidate. Upon his inauguration, he became the oldest president in American history, breaking the record set by his predecessor Trump. Biden entered office amid the COVID-19 pandemic, an economic crisis, and increased political polarization.On the first day of his presidency, Biden made an effort to revert President Trump's energy policy by restoring U.S. participation in the Paris Agreement and revoking the permit for the Keystone XL pipeline. He also halted funding for Trump's border wall, an expansion of the Mexican border wall. On his second day, he issued a series of executive orders to reduce the impact of COVID-19, including invoking the Defense Production Act of 1950, and set an early goal of achieving one hundred million COVID-19 vaccinations in the United States in his first 100 days.Biden signed into law the American Rescue Plan Act of 2021; a $1.9 trillion stimulus bill that temporarily established expanded unemployment insurance and sent $1,400 stimulus checks to most Americans in response to continued economic pressure from COVID-19. He signed the bipartisan Infrastructure Investment and Jobs Act; a ten-year plan brokered by Biden alongside Democrats and Republicans in Congress, to invest in American roads, bridges, public transit, ports and broadband access. Biden signed the Juneteenth National Independence Day Act, making Juneteenth a federal holiday in the United States. He appointed Ketanji Brown Jackson to the U.S. Supreme Court—the first Black woman to serve on the court. After The Supreme Court overturned Roe v. Wade, Biden took executive actions, such as the signing of Executive Order 14076, to preserve and protect women's health rights nationwide, against abortion bans in Republican led states. Biden proposed a significant expansion of the U.S. social safety net through the Build Back Better Act, but those efforts, along with voting rights legislation, failed in Congress. However, in August 2022, Biden signed the Inflation Reduction Act of 2022, a domestic appropriations bill that included some of the provisions of the Build Back Better Act after the entire bill failed to pass. It included significant federal investment in climate and domestic clean energy production, tax credits for solar panels, electric cars and other home energy programs as well as a three-year extension of Affordable Care Act subsidies. The administration's economic policies, known as \"Bidenomics\", were inspired and designed by Trickle-up economics. Described as growing the economy from the middle out and bottom up and growing the middle class. Biden signed the CHIPS and Science Act, bolstering the semiconductor and manufacturing industry, the Honoring our PACT Act, expanding health care for US veterans, the Bipartisan Safer Communities Act and the Electoral Count Reform and Presidential Transition Improvement Act. In late 2022, Biden signed the Respect for Marriage Act, which repealed the Defense of Marriage Act and codified same-sex and interracial marriage in the United States. In response to the debt-ceiling crisis of 2023, Biden negotiated and signed the Fiscal Responsibility Act of 2023, which restrains federal spending for fiscal years 2024 and 2025, implements minor changes to SNAP and TANF, includes energy permitting reform, claws back some IRS funding and unspent money for COVID-19, and suspends the debt ceiling to January 1, 2025. Biden established the American Climate Corps and created the first ever White House Office of Gun Violence Prevention. On September 26, 2023, Joe Biden visited a United Auto Workers picket line during the 2023 United Auto Workers strike, making him the first US president to visit one.\n", + "The foreign policy goal of the Biden administration is to restore the US to a \"position of trusted leadership\" among global democracies in order to address the challenges posed by Russia and China. In foreign policy, Biden completed the withdrawal of U.S. military forces from Afghanistan, declaring an end to nation-building efforts and shifting U.S. foreign policy toward strategic competition with China and, to a lesser extent, Russia. However, during the withdrawal, the Afghan government collapsed and the Taliban seized control, leading to Biden receiving bipartisan criticism. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia as well as providing Ukraine with over $100 billion in combined military, economic, and humanitarian aid. Biden also approved a raid which led to the death of Abu Ibrahim al-Hashimi al-Qurashi, the leader of the Islamic State, and approved a drone strike which killed Ayman Al Zawahiri, leader of Al-Qaeda. Biden signed and created AUKUS, an international security alliance, together with Australia and the United Kingdom. Biden called for the expansion of NATO with the addition of Finland and Sweden, and rallied NATO allies in support of Ukraine. During the 2023 Israel–Hamas war, Biden condemned Hamas and other Palestinian militants as terrorism and announced American military support for Israel; Biden also showed his support and sympathy towards Palestinians affected by the war, sent humanitarian aid, and brokered a four-day temporary pause and hostage exchange.\n", + "\n", + "Page: Family of Joe Biden\n", + "Summary: Joe Biden, the 46th and current president of the United States, has family members who are prominent in law, education, activism and politics.

It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the 2nd smallest and 6th least populous state, but also the 6th most densely populated. Delaware's most populous city is Wilmington, and the state's capital is Dover, the 2nd most populous city in Delaware. The state is divided into three counties, the fewest number of counties of any of the 50 U.S. states; from north to south, the three counties are: New Castle County, Kent County, and Sussex County.\n", + "The southern two counties, Kent and Sussex counties, historically have been predominantly agrarian economies. New Castle is more urbanized and is considered part of the Delaware Valley metropolitan statistical area that surrounds and includes Philadelphia, the nation's 6th most populous city. Delaware is considered part of the Southern United States by the U.S. Census Bureau, but the state's geography, culture, and history are a hybrid of the Mid-Atlantic and Northeastern regions of the country.Before Delaware coastline was explored and developed by Europeans in the 16th century, the state was inhabited by several Native Americans tribes, including the Lenape in the north and Nanticoke in the south. The state was first colonized by Dutch traders at Zwaanendael, near present-day Lewes, Delaware, in 1631.\n", + "Delaware was one of the Thirteen Colonies that participated in the American Revolution and American Revolutionary War, in which the American Continental Army, led by George Washington, defeated the British, ended British colonization and establishing the United States as a sovereign and independent nation.\n", + "On December 7, 1787, Delaware was the first state to ratify the Constitution of the United States, earning it the nickname \"The First State\".Since the turn of the 20th century, Delaware has become an onshore corporate haven whose corporate laws are deemed appealing to corporations; over half of all New York Stock Exchange-listed corporations and over three-fifths of the Fortune 500 is legally incorporated in the state.\n", + "\n", + "Page: Delaware City, Delaware\n", + "Summary: Delaware City is a city in New Castle County, Delaware, United States. The population was 1,885 as of 2020. It is a small port town on the eastern terminus of the Chesapeake and Delaware Canal and is the location of the Forts Ferry Crossing to Fort Delaware on Pea Patch Island.\n", + "\n", + "Page: Delaware River\n", + "Summary: The Delaware River is a major river in the Mid-Atlantic region of the United States and is the longest free-flowing (undammed) river in the Eastern United States. From the meeting of its branches in Hancock, New York, the river flows for 282 miles (454 km) along the borders of New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay.\n", + "The river has been recognized by the National Wildlife Federation as one of the country's Great Waters and has been called the \"Lifeblood of the Northeast\" by American Rivers. Its watershed drains an area of 13,539 square miles (35,070 km2) and provides drinking water for 17 million people, including half of New York City via the Delaware Aqueduct.\n", + "The Delaware River has two branches that rise in the Catskill Mountains of New York: the West Branch at Mount Jefferson in Jefferson, Schoharie County, and the East Branch at Grand Gorge, Delaware County. The branches merge to form the main Delaware River at Hancock, New York. Flowing south, the river remains relatively undeveloped, with 152 miles (245 km) protected as the Upper, Middle, and Lower Delaware National Scenic Rivers. At Trenton, New Jersey, the Delaware becomes tidal, navigable, and significantly more industrial. This section forms the backbone of the Delaware Valley metropolitan area, serving the port cities of Philadelphia, Camden, New Jersey, and Wilmington, Delaware. The river flows into Delaware Bay at Liston Point, 48 miles (77 km) upstream of the bay's outlet to the Atlantic Ocean between Cape May and Cape Henlopen.\n", + "Before the arrival of European settlers, the river was the homeland of the Lenape native people. They called the river Lenapewihittuk, or Lenape River, and Kithanne, meaning the largest river in this part of the country.In 1609, the river was visited by a Dutch East India Company expedition led by Henry Hudson. Hudson, an English navigator, was hired to find a western route to Cathay (China), but his encounters set the stage for Dutch colonization of North America in the 17th century. Early Dutch and Swedish settlements were established along the lower section of the river and Delaware Bay. Both colonial powers called the river the South River (Zuidrivier), compared to the Hudson River, which was known as the North River. After the English expelled the Dutch and took control of the New Netherland colony in 1664, the river was renamed Delaware after Sir Thomas West, 3rd Baron De La Warr, an English nobleman and the Virginia colony's first royal governor, who defended the colony during the First Anglo-Powhatan War.\n", + "\n", + "Page: University of Delaware\n", + "Summary: The University of Delaware (colloquially known as UD or Delaware) is a privately governed, state-assisted land-grant research university located in Newark, Delaware. UD is the largest university in Delaware. It offers three associate's programs, 148 bachelor's programs, 121 master's programs (with 13 joint degrees), and 55 doctoral programs across its eight colleges. The main campus is in Newark, with satellite campuses in Dover, Wilmington, Lewes, and Georgetown. It is considered a large institution with approximately 18,200 undergraduate and 4,200 graduate students. It is a privately governed university which receives public funding for being a land-grant, sea-grant, and space-grant state-supported research institution.UD is classified among \"R1: Doctoral Universities – Very high research activity\". According to the National Science Foundation, UD spent $186 million on research and development in 2018, ranking it 119th in the nation. It is recognized with the Community Engagement Classification by the Carnegie Foundation for the Advancement of Teaching.UD students, alumni, and sports teams are known as the \"Fightin' Blue Hens\", more commonly shortened to \"Blue Hens\", and the school colors are Delaware blue and gold. UD sponsors 21 men's and women's NCAA Division-I sports teams and have competed in the Colonial Athletic Association (CAA) since 2001.\n", + "\n", + "\n", + "\n", + "Page: Lenape\n", + "Summary: The Lenape (English: , , ; Lenape languages: [lənaːpe]), also called the Lenni Lenape and Delaware people, are an Indigenous people of the Northeastern Woodlands, who live in the United States and Canada.The Lenape's historical territory includes present-day northeastern Delaware, all of New Jersey, the eastern Pennsylvania regions of the Lehigh Valley and Northeastern Pennsylvania, and New York Bay, western Long Island, and the lower Hudson Valley in New York state. Today they are based in Oklahoma, Wisconsin, and Ontario.\n", + "During the last decades of the 18th century, European settlers and the effects of the American Revolutionary War displaced most Lenape from their homelands and pushed them north and west. In the 1860s, under the Indian removal policy, the U.S. federal government relocated most Lenape remaining in the Eastern United States to the Indian Territory and surrounding regions. Lenape people currently belong to the Delaware Nation and Delaware Tribe of Indians in Oklahoma, the Stockbridge–Munsee Community in Wisconsin, and the Munsee-Delaware Nation, Moravian of the Thames First Nation, and Delaware of Six Nations in Ontario.\n", + "\n", + "\u001b[0m" + ] + }, + { + "ename": "BadRequestError", + "evalue": "Error code: 400 - {'error': {'message': \"This model's maximum context length is 4097 tokens.

The officeholder leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the number of presidencies and the number of individuals who have served as president. The incumbent president is Joe Biden.The presidency of William Henry Harrison, who died 31 days after taking office in 1841, was the shortest in American history. Franklin D. Roosevelt served the longest, over twelve years, before dying early in his fourth term in 1945. He is the only U.S. president to have served more than two terms. Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once.Four presidents died in office of natural causes (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy), and one resigned (Richard Nixon, facing impeachment and removal from office). John Tyler was the first vice president to assume the presidency during a presidential term, and set the precedent that a vice president who does so becomes the fully functioning president with his presidency.Throughout most of its history, American politics has been dominated by political parties. The Constitution is silent on the issue of political parties, and at the time it came into force in 1789, no organized parties existed. Soon after the 1st Congress convened, political factions began rallying around dominant Washington administration officials, such as Alexander Hamilton and Thomas Jefferson. Concerned about the capacity of political parties to destroy the fragile unity holding the nation together, Washington remained unaffiliated with any political faction or party throughout his eight-year presidency. He was, and remains, the only U.S. president never affiliated with a political party.\n", + "\n", + "Page: List of presidents of the United States by age\n", + "Summary: In this list of presidents of the United States by age, the first table charts the age of each president of the United States at the time of presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Where the president is still living, their lifespan and post-presidency timespan are calculated up to January 25, 2024.\n", + "\n", + "Page: List of vice presidents of the United States\n", + "Summary: There have been 49 vice presidents of the United States since the office was created in 1789. Originally, the vice president was the person who received the second-most votes for president in the Electoral College. But after the election of 1800 produced a tie between Thomas Jefferson and Aaron Burr, requiring the House of Representatives to choose between them, lawmakers acted to prevent such a situation from recurring. The Twelfth Amendment was added to the Constitution in 1804, creating the current system where electors cast a separate ballot for the vice presidency.The vice president is the first person in the presidential line of succession—that is, they assume the presidency if the president dies, resigns, or is impeached and removed from office. Nine vice presidents have ascended to the presidency in this way: eight (John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, and Lyndon B. Johnson) through the president's death and one (Gerald Ford) through the president's resignation. The vice president also serves as the president of the Senate and may choose to cast a tie-breaking vote on decisions made by the Senate. Vice presidents have exercised this latter power to varying extents over the years.Before adoption of the Twenty-fifth Amendment in 1967, an intra-term vacancy in the office of the vice president could not be filled until the next post-election inauguration. Several such vacancies occurred: seven vice presidents died, one resigned and eight succeeded to the presidency. This amendment allowed for a vacancy to be filled through appointment by the president and confirmation by both chambers of the Congress. Since its ratification, the vice presidency has been vacant twice (both in the context of scandals surrounding the Nixon administration) and was filled both times through this process, namely in 1973 following Spiro Agnew's resignation, and again in 1974 after Gerald Ford succeeded to the presidency. The amendment also established a procedure whereby a vice president may, if the president is unable to discharge the powers and duties of the office, temporarily assume the powers and duties of the office as acting president. Three vice presidents have briefly acted as president under the 25th Amendment: George H. W. Bush on July 13, 1985; Dick Cheney on June 29, 2002, and on July 21, 2007; and Kamala Harris on November 19, 2021.\n", + "The persons who have served as vice president were born in or primarily affiliated with 27 states plus the District of Columbia. New York has produced the most of any state as eight have been born there and three others considered it their home state. Most vice presidents have been in their 50s or 60s and had political experience before assuming the office. Two vice presidents—George Clinton and John C. Calhoun—served under more than one president. Ill with tuberculosis and recovering in Cuba on Inauguration Day in 1853, William R. King, by an Act of Congress, was allowed to take the oath outside the United States. He is the only vice president to take his oath of office in a foreign country.\n", + "\n", + "Page: List of presidents of the United States by net worth\n", + "Summary: The list of presidents of the United States by net worth at peak varies greatly. Debt and depreciation often means that presidents' net worth is less than $0 at the time of death. Most presidents before 1845 were extremely wealthy, especially Andrew Jackson and George Washington. \t \n", + "Presidents since 1929, when Herbert Hoover took office, have generally been wealthier than presidents of the late nineteenth and early twentieth centuries; with the exception of Harry S. Truman, all presidents since this time have been millionaires. These presidents have often received income from autobiographies and other writing. Except for Franklin D. Roosevelt and John F. Kennedy (both of whom died while in office), all presidents beginning with Calvin Coolidge have written autobiographies. In addition, many presidents—including Bill Clinton—have earned considerable income from public speaking after leaving office.The richest president in history may be Donald Trump. However, his net worth is not precisely known because the Trump Organization is privately held.Truman was among the poorest U.S. presidents, with a net worth considerably less than $1 million. His financial situation contributed to the doubling of the presidential salary to $100,000 in 1949. In addition, the presidential pension was created in 1958 when Truman was again experiencing financial difficulties. Harry and Bess Truman received the first Medicare cards in 1966 via the Social Security Act of 1965.\n", + "\n", + "Page: List of presidents of the United States by home state\n", + "Summary: These lists give the states of primary affiliation and of birth for each president of the United States.\u001b[0m\u001b[32;1m\u001b[1;3m\n", + "Invoking: `Wikipedia` with `Joe Biden`\n", + "\n", + "\n", + "\u001b[0m\u001b[36;1m\u001b[1;3mPage: Joe Biden\n", + "Summary: Joseph Robinette Biden Jr. ( BY-dən; born November 20, 1942) is an American politician who is the 46th and current president of the United States.

As a senator, Biden drafted and led the effort to pass the Violent Crime Control and Law Enforcement Act and the Violence Against Women Act. He also oversaw six U.S. Supreme Court confirmation hearings, including the contentious hearings for Robert Bork and Clarence Thomas. Biden ran unsuccessfully for the Democratic presidential nomination in 1988 and 2008. In 2008, Obama chose Biden as his running mate, and he was a close counselor to Obama during his two terms as vice president.

Biden, a Democrat from Delaware who previously served as vice president for two terms under president Barack Obama, took office following his victory in the 2020 presidential election over Republican incumbent president Donald Trump. Biden won the presidency with a popular vote of over 81 million, the highest number of votes cast for a single United States presidential candidate. Upon his inauguration, he became the oldest president in American history, breaking the record set by his predecessor Trump. Biden entered office amid the COVID-19 pandemic, an economic crisis, and increased political polarization.On the first day of his presidency, Biden made an effort to revert President Trump's energy policy by restoring U.S. participation in the Paris Agreement and revoking the permit for the Keystone XL pipeline. He also halted funding for Trump's border wall, an expansion of the Mexican border wall. On his second day, he issued a series of executive orders to reduce the impact of COVID-19, including invoking the Defense Production Act of 1950, and set an early goal of achieving one hundred million COVID-19 vaccinations in the United States in his first 100 days.Biden signed into law the American Rescue Plan Act of 2021; a $1.9 trillion stimulus bill that temporarily established expanded unemployment insurance and sent $1,400 stimulus checks to most Americans in response to continued economic pressure from COVID-19. He signed the bipartisan Infrastructure Investment and Jobs Act; a ten-year plan brokered by Biden alongside Democrats and Republicans in Congress, to invest in American roads, bridges, public transit, ports and broadband access. Biden signed the Juneteenth National Independence Day Act, making Juneteenth a federal holiday in the United States. He appointed Ketanji Brown Jackson to the U.S. Supreme Court—the first Black woman to serve on the court. After The Supreme Court overturned Roe v. Wade, Biden took executive actions, such as the signing of Executive Order 14076, to preserve and protect women's health rights nationwide, against abortion bans in Republican led states. Biden proposed a significant expansion of the U.S. social safety net through the Build Back Better Act, but those efforts, along with voting rights legislation, failed in Congress. However, in August 2022, Biden signed the Inflation Reduction Act of 2022, a domestic appropriations bill that included some of the provisions of the Build Back Better Act after the entire bill failed to pass. It included significant federal investment in climate and domestic clean energy production, tax credits for solar panels, electric cars and other home energy programs as well as a three-year extension of Affordable Care Act subsidies. The administration's economic policies, known as \"Bidenomics\", were inspired and designed by Trickle-up economics. Described as growing the economy from the middle out and bottom up and growing the middle class. Biden signed the CHIPS and Science Act, bolstering the semiconductor and manufacturing industry, the Honoring our PACT Act, expanding health care for US veterans, the Bipartisan Safer Communities Act and the Electoral Count Reform and Presidential Transition Improvement Act. In late 2022, Biden signed the Respect for Marriage Act, which repealed the Defense of Marriage Act and codified same-sex and interracial marriage in the United States. In response to the debt-ceiling crisis of 2023, Biden negotiated and signed the Fiscal Responsibility Act of 2023, which restrains federal spending for fiscal years 2024 and 2025, implements minor changes to SNAP and TANF, includes energy permitting reform, claws back some IRS funding and unspent money for COVID-19, and suspends the debt ceiling to January 1, 2025.

In foreign policy, Biden completed the withdrawal of U.S. military forces from Afghanistan, declaring an end to nation-building efforts and shifting U.S. foreign policy toward strategic competition with China and, to a lesser extent, Russia. However, during the withdrawal, the Afghan government collapsed and the Taliban seized control, leading to Biden receiving bipartisan criticism. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia as well as providing Ukraine with over $100 billion in combined military, economic, and humanitarian aid. Biden also approved a raid which led to the death of Abu Ibrahim al-Hashimi al-Qurashi, the leader of the Islamic State, and approved a drone strike which killed Ayman Al Zawahiri, leader of Al-Qaeda. Biden signed and created AUKUS, an international security alliance, together with Australia and the United Kingdom. Biden called for the expansion of NATO with the addition of Finland and Sweden, and rallied NATO allies in support of Ukraine.

It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the 2nd smallest and 6th least populous state, but also the 6th most densely populated. Delaware's most populous city is Wilmington, and the state's capital is Dover, the 2nd most populous city in Delaware. The state is divided into three counties, the fewest number of counties of any of the 50 U.S. states; from north to south, the three counties are: New Castle County, Kent County, and Sussex County.\n", + "The southern two counties, Kent and Sussex counties, historically have been predominantly agrarian economies. New Castle is more urbanized and is considered part of the Delaware Valley metropolitan statistical area that surrounds and includes Philadelphia, the nation's 6th most populous city. Delaware is considered part of the Southern United States by the U.S. Census Bureau, but the state's geography, culture, and history are a hybrid of the Mid-Atlantic and Northeastern regions of the country.Before Delaware coastline was explored and developed by Europeans in the 16th century, the state was inhabited by several Native Americans tribes, including the Lenape in the north and Nanticoke in the south. The state was first colonized by Dutch traders at Zwaanendael, near present-day Lewes, Delaware, in 1631.\n", + "Delaware was one of the Thirteen Colonies that participated in the American Revolution and American Revolutionary War, in which the American Continental Army, led by George Washington, defeated the British, ended British colonization and establishing the United States as a sovereign and independent nation.\n", + "On December 7, 1787, Delaware was the first state to ratify the Constitution of the United States, earning it the nickname \"The First State\".Since the turn of the 20th century, Delaware has become an onshore corporate haven whose corporate laws are deemed appealing to corporations; over half of all New York Stock Exchange-listed corporations and over three-fifths of the Fortune 500 is legally incorporated in the state.\n", + "\n", + "Page: Delaware City, Delaware\n", + "Summary: Delaware City is a city in New Castle County, Delaware, United States.

The branches merge to form the main Delaware River at Hancock, New York. Flowing south, the river remains relatively undeveloped, with 152 miles (245 km) protected as the Upper, Middle, and Lower Delaware National Scenic Rivers. At Trenton, New Jersey, the Delaware becomes tidal, navigable, and significantly more industrial. This section forms the backbone of the Delaware Valley metropolitan area, serving the port cities of Philadelphia, Camden, New Jersey, and Wilmington, Delaware. The river flows into Delaware Bay at Liston Point, 48 miles (77 km) upstream of the bay's outlet to the Atlantic Ocean between Cape May and Cape Henlopen.\n", + "Before the arrival of European settlers, the river was the homeland of the Lenape native people. They called the river Lenapewihittuk, or Lenape River, and Kithanne, meaning the largest river in this part of the country.In 1609, the river was visited by a Dutch East India Company expedition led by Henry Hudson. Hudson, an English navigator, was hired to find a western route to Cathay (China), but his encounters set the stage for Dutch colonization of North America in the 17th century. Early Dutch and Swedish settlements were established along the lower section of the river and Delaware Bay. Both colonial powers called the river the South River (Zuidrivier), compared to the Hudson River, which was known as the North River. After the English expelled the Dutch and took control of the New Netherland colony in 1664, the river was renamed Delaware after Sir Thomas West, 3rd Baron De La Warr, an English nobleman and the Virginia colony's first royal governor, who defended the colony during the First Anglo-Powhatan War.\n", + "\n", + "Page: University of Delaware\n", + "Summary: The University of Delaware (colloquially known as UD or Delaware) is a privately governed, state-assisted land-grant research university located in Newark, Delaware.

UD will continue to compete in both sides of the CAA in 2024–25; it will be ineligible for the FCS playoffs due to NCAA rules for transitioning programs, but will be eligible for all non-football CAA championships. Upon joining CUSA, UD will be eligible for all conference championship events except the football championship game; it will become eligible for that event upon completing the FBS transition in 2026. At the same time, UD also announced it would add one women's sport due to Title IX considerations, and would also be seeking conference homes for the seven sports that UD sponsors but CUSA does not. The new women's sport would later be announced as ice hockey; UD will join College Hockey America for its first season of varsity play in 2025–26.\n", + "\n", + "Page: Brahma chicken\n", + "Summary: The Brahma is an American breed of chicken.

The breed has several other unusual qualities, such as black skin and bones, blue earlobes, and five toes on each foot, whereas most chickens have only four. They are often exhibited in poultry shows, and also appear in various colors. In addition to their distinctive physical characteristics, Silkies are well known for their calm and friendly temperament. It is among the most docile of poultry. Hens are also exceptionally broody, and care for young well. Although they are fair layers themselves, laying only about three eggs a week, they are commonly used to hatch eggs from other breeds and bird species due to their broody nature. Silkie chickens have been bred to have a wide variety of colors which include but are not limited to: Black, Blue, Buff, Partridge, Splash, White, Lavender, Paint and Porcelain.\n", + "\n", + "Page: Silverudd Blue\n", + "Summary: The Silverudd Blue, Swedish: Silverudds Blå, is a Swedish breed of chicken.

This allows you to interact in a chat manner with this LLM, so it remembers previous questions. +Finally, we will build an agent - which utilizes an LLM to determine whether or not it needs to fetch data to answer questions. +We will cover these at a high level, but there are lot of details to all of these! +We will link to relevant docs. + +## LLM Chain + +We'll show how to use models available via API, like OpenAI, and local open source models, using integrations like Ollama. + + + + +First we'll need to import the LangChain x OpenAI integration package. + +```shell +pip install langchain-openai +``` + +Accessing the API requires an API key, which you can get by creating an account and heading [here](https://platform.openai.com/account/api-keys). Once we have a key we'll want to set it as an environment variable by running: + +```shell +export OPENAI_API_KEY="..." +``` + +We can then initialize the model: + +```python +from langchain_openai import ChatOpenAI + +llm = ChatOpenAI() +``` + +If you'd prefer not to set an environment variable you can pass the key in directly via the `api_key` named parameter when initiating the OpenAI LLM class: + +```python +from langchain_openai import ChatOpenAI + +llm = ChatOpenAI(api_key="...") +``` + + + + +[Ollama](https://ollama.ai/) allows you to run open-source large language models, such as Llama 2, locally. + +First, follow [these instructions](https://github.com/jmorganca/ollama) to set up and run a local Ollama instance: + +* [Download](https://ollama.ai/download) +* Fetch a model via `ollama pull llama2` + +Then, make sure the Ollama server is running. After that, you can do: +```python +from langchain_community.llms import Ollama +llm = Ollama(model="llama2") +``` + + + + +First we'll need to import the LangChain x Anthropic package. + +```shell +pip install langchain-anthropic +``` + +Accessing the API requires an API key, which you can get by creating an account [here](https://claude.ai/login). Once we have a key we'll want to set it as an environment variable by running: + +```shell +export ANTHROPIC_API_KEY="..." +``` + +We can then initialize the model: + +```python +from langchain_anthropic import ChatAnthropic + +llm = ChatAnthropic(model="claude-3-sonnet-20240229", temperature=0.2, max_tokens=1024) +``` + +If you'd prefer not to set an environment variable you can pass the key in directly via the `api_key` named parameter when initiating the Anthropic Chat Model class: + +```python +llm = ChatAnthropic(api_key="...") +``` + + + + +First we'll need to import the Cohere SDK package. + +```shell +pip install langchain-cohere +``` + +Accessing the API requires an API key, which you can get by creating an account and heading [here](https://dashboard.cohere.com/api-keys).

It still won't know the answer, but it should respond in a more proper tone for a technical writer! + +```python +chain.invoke({"input": "how can langsmith help with testing?"}) +``` + +The output of a ChatModel (and therefore, of this chain) is a message. However, it's often much more convenient to work with strings. Let's add a simple output parser to convert the chat message to a string. + +```python +from langchain_core.output_parsers import StrOutputParser + +output_parser = StrOutputParser() +``` + +We can now add this to the previous chain: + +```python +chain = prompt | llm | output_parser +``` + +We can now invoke it and ask the same question. The answer will now be a string (rather than a ChatMessage). + +```python +chain.invoke({"input": "how can langsmith help with testing?"}) +``` + +### Diving Deeper + +We've now successfully set up a basic LLM chain. We only touched on the basics of prompts, models, and output parsers - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/model_io). + + +## Retrieval Chain + +To properly answer the original question ("how can langsmith help with testing?"), we need to provide additional context to the LLM. +We can do this via *retrieval*. +Retrieval is useful when you have **too much data** to pass to the LLM directly. +You can then use a retriever to fetch only the most relevant pieces and pass those in. + +In this process, we will look up relevant documents from a *Retriever* and then pass them into the prompt. +A Retriever can be backed by anything - a SQL table, the internet, etc - but in this instance we will populate a vector store and use that as a retriever. For more information on vectorstores, see [this documentation](/docs/modules/data_connection/vectorstores). + +First, we need to load the data that we want to index. To do this, we will use the WebBaseLoader. This requires installing [BeautifulSoup](https://beautiful-soup-4.readthedocs.io/en/latest/): + +```shell +pip install beautifulsoup4 +``` + +After that, we can import and use WebBaseLoader. + + +```python +from langchain_community.document_loaders import WebBaseLoader +loader = WebBaseLoader("https://docs.smith.langchain.com/user_guide") + +docs = loader.load() +``` + +Next, we need to index it into a vectorstore. This requires a few components, namely an [embedding model](/docs/modules/data_connection/text_embedding) and a [vectorstore](/docs/modules/data_connection/vectorstores). + +For embedding models, we once again provide examples for accessing via API or by running local models. + + + + +Make sure you have the `langchain_openai` package installed an the appropriate environment variables set (these are the same as needed for the LLM). + +```python +from langchain_openai import OpenAIEmbeddings + +embeddings = OpenAIEmbeddings() +``` + + + + +Make sure you have Ollama running (same set up as with the LLM). + +```python +from langchain_community.embeddings import OllamaEmbeddings + +embeddings = OllamaEmbeddings() +``` + + + +Make sure you have the `cohere` package installed and the appropriate environment variables set (these are the same as needed for the LLM). + +```python +from langchain_cohere.embeddings import CohereEmbeddings + +embeddings = CohereEmbeddings() +``` + + + + +Now, we can use this embedding model to ingest documents into a vectorstore. +We will use a simple local vectorstore, [FAISS](/docs/integrations/vectorstores/faiss), for simplicity's sake. + +First we need to install the required packages for that: + +```shell +pip install faiss-cpu +``` + +Then we can build our index: + +```python +from langchain_community.vectorstores import FAISS +from langchain_text_splitters import RecursiveCharacterTextSplitter + + +text_splitter = RecursiveCharacterTextSplitter() +documents = text_splitter.split_documents(docs) +vector = FAISS.from_documents(documents, embeddings) +``` + +Now that we have this data indexed in a vectorstore, we will create a retrieval chain. +This chain will take an incoming question, look up relevant documents, then pass those documents along with the original question into an LLM and ask it to answer the original question. + +First, let's set up the chain that takes a question and the retrieved documents and generates an answer. + +```python +from langchain.chains.combine_documents import create_stuff_documents_chain + +prompt = ChatPromptTemplate.from_template("""Answer the following question based only on the provided context: + + +{context} + + +Question: {input}""") + +document_chain = create_stuff_documents_chain(llm, prompt) +``` + +If we wanted to, we could run this ourselves by passing in documents directly: + +```python +from langchain_core.documents import Document + +document_chain.invoke({ + "input": "how can langsmith help with testing?", + "context": [Document(page_content="langsmith can let you visualize test results")] +}) +``` + +However, we want the documents to first come from the retriever we just set up. +That way, we can use the retriever to dynamically select the most relevant documents and pass those in for a given question. + +```python +from langchain.chains import create_retrieval_chain + +retriever = vector.as_retriever() +retrieval_chain = create_retrieval_chain(retriever, document_chain) +``` + +We can now invoke this chain. This returns a dictionary - the response from the LLM is in the `answer` key + +```python +response = retrieval_chain.invoke({"input": "how can langsmith help with testing?"}) +print(response["answer"]) + +# LangSmith offers several features that can help with testing:... +``` + +This answer should be much more accurate! + +### Diving Deeper + +We've now successfully set up a basic retrieval chain. We only touched on the basics of retrieval - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/data_connection). + +## Conversation Retrieval Chain + +The chain we've created so far can only answer single questions. One of the main types of LLM applications that people are building are chat bots. So how do we turn this chain into one that can answer follow up questions? + +We can still use the `create_retrieval_chain` function, but we need to change two things: + +1. The retrieval method should now not just work on the most recent input, but rather should take the whole history into account. +2. The final LLM chain should likewise take the whole history into account + +**Updating Retrieval** + +In order to update retrieval, we will create a new chain. This chain will take in the most recent input (`input`) and the conversation history (`chat_history`) and use an LLM to generate a search query. + +```python +from langchain.chains import create_history_aware_retriever +from langchain_core.prompts import MessagesPlaceholder + +# First we need a prompt that we can pass into an LLM to generate this search query + +prompt = ChatPromptTemplate.from_messages([ + MessagesPlaceholder(variable_name="chat_history"), + ("user", "{input}"), + ("user", "Given the above conversation, generate a search query to look up to get information relevant to the conversation") +]) +retriever_chain = create_history_aware_retriever(llm, retriever, prompt) +``` + +We can test this out by passing in an instance where the user asks a follow-up question. + +```python +from langchain_core.messages import HumanMessage, AIMessage + +chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")] +retriever_chain.invoke({ + "chat_history": chat_history, + "input": "Tell me how" +}) +``` +You should see that this returns documents about testing in LangSmith. This is because the LLM generated a new query, combining the chat history with the follow-up question. + +Now that we have this new retriever, we can create a new chain to continue the conversation with these retrieved documents in mind. + +```python +prompt = ChatPromptTemplate.from_messages([ + ("system", "Answer the user's questions based on the below context:\n\n{context}"), + MessagesPlaceholder(variable_name="chat_history"), + ("user", "{input}"), +]) +document_chain = create_stuff_documents_chain(llm, prompt) + +retrieval_chain = create_retrieval_chain(retriever_chain, document_chain) +``` + +We can now test this out end-to-end: + +```python +chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")] +retrieval_chain.invoke({ + "chat_history": chat_history, + "input": "Tell me how" +}) +``` +We can see that this gives a coherent answer - we've successfully turned our retrieval chain into a chatbot! + +## Agent + +We've so far created examples of chains - where each step is known ahead of time. +The final thing we will create is an agent - where the LLM decides what steps to take. + +**NOTE: for this example we will only show how to create an agent using OpenAI models, as local models are not reliable enough yet.** + +One of the first things to do when building an agent is to decide what tools it should have access to. +For this example, we will give the agent access to two tools: + +1. The retriever we just created. This will let it easily answer questions about LangSmith +2. A search tool. This will let it easily answer questions that require up-to-date information. + +First, let's set up a tool for the retriever we just created: + +```python +from langchain.tools.retriever import create_retriever_tool + +retriever_tool = create_retriever_tool( + retriever, + "langsmith_search", + "Search for information about LangSmith. For any questions about LangSmith, you must use this tool!", +) +``` + + +The search tool that we will use is [Tavily](/docs/integrations/retrievers/tavily). This will require an API key (they have generous free tier). After creating it on their platform, you need to set it as an environment variable: + +```shell +export TAVILY_API_KEY=... +``` +If you do not want to set up an API key, you can skip creating this tool. + +```python +from langchain_community.tools.tavily_search import TavilySearchResults + +search = TavilySearchResults() +``` + +We can now create a list of the tools we want to work with: + +```python +tools = [retriever_tool, search] +``` + +Now that we have the tools, we can create an agent to use them. We will go over this pretty quickly - for a deeper dive into what exactly is going on, check out the [Agent's Getting Started documentation](/docs/modules/agents) + +Install langchain hub first +```bash +pip install langchainhub +``` +Install the langchain-openai package +To interact with OpenAI we need to use langchain-openai which connects with OpenAI SDK[https://github.com/langchain-ai/langchain/tree/master/libs/partners/openai]. +```bash +pip install langchain-openai +``` + +Now we can use it to get a predefined prompt + +```python +from langchain_openai import ChatOpenAI +from langchain import hub +from langchain.agents import create_openai_functions_agent +from langchain.agents import AgentExecutor + +# Get the prompt to use - you can modify this! +prompt = hub.pull("hwchase17/openai-functions-agent") + +# You need to set OPENAI_API_KEY environment variable or pass it as argument `api_key`. +llm = ChatOpenAI(model="gpt-3.5-turbo", temperature=0) +agent = create_openai_functions_agent(llm, tools, prompt) +agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True) +``` + +We can now invoke the agent and see how it responds! We can ask it questions about LangSmith: + +```python +agent_executor.invoke({"input": "how can langsmith help with testing?"}) +``` + +We can ask it about the weather: + +```python +agent_executor.invoke({"input": "what is the weather in SF?"}) +``` + +We can have conversations with it: + +```python +chat_history = [HumanMessage(content="Can LangSmith help test my LLM applications?"), AIMessage(content="Yes!")] +agent_executor.invoke({ + "chat_history": chat_history, + "input": "Tell me how" +}) +``` + +### Diving Deeper + +We've now successfully set up a basic agent. We only touched on the basics of agents - for a deeper dive into everything mentioned here, see [this section of documentation](/docs/modules/agents). + + +## Serving with LangServe + +Now that we've built an application, we need to serve it. That's where LangServe comes in. +LangServe helps developers deploy LangChain chains as a REST API. You do not need to use LangServe to use LangChain, but in this guide we'll show how you can deploy your app with LangServe. + +While the first part of this guide was intended to be run in a Jupyter Notebook, we will now move out of that. We will be creating a Python file and then interacting with it from the command line. + +Install with: +```bash +pip install "langserve[all]" +``` + +### Server + +To create a server for our application we'll make a `serve.py` file. This will contain our logic for serving our application. It consists of three things: +1. The definition of our chain that we just built above +2. Our FastAPI app +3. A definition of a route from which to serve the chain, which is done with `langserve.add_routes` + +```python +#!/usr/bin/env python +from typing import List + +from fastapi import FastAPI +from langchain_core.prompts import ChatPromptTemplate +from langchain_openai import ChatOpenAI +from langchain_community.document_loaders import WebBaseLoader +from langchain_openai import OpenAIEmbeddings +from langchain_community.vectorstores import FAISS +from langchain_text_splitters import RecursiveCharacterTextSplitter +from langchain.tools.retriever import create_retriever_tool +from langchain_community.tools.tavily_search import TavilySearchResults +from langchain import hub +from langchain.agents import create_openai_functions_agent +from langchain.agents import AgentExecutor +from langchain.pydantic_v1 import BaseModel, Field +from langchain_core.messages import BaseMessage +from langserve import add_routes + +# 1.

If we execute this file: +```bash +python serve.py +``` +we should see our chain being served at localhost:8000. + +### Playground + +Every LangServe service comes with a simple built-in UI for configuring and invoking the application with streaming output and visibility into intermediate steps. +Head to http://localhost:8000/agent/playground/ to try it out!

Here are some key examples: + +- Query per second (QPS): This measures the number of queries your model processes in a second, offering insights into its utilization. +- Latency: This metric quantifies the delay from when your client sends a request to when they receive a response. +- Tokens Per Second (TPS): This represents the number of tokens your model can generate in a second. + +**Quality Metrics:** These metrics are typically customized according to the business use-case. For instance, how does the output of your system compare to a baseline, such as a previous version? Although these metrics can be calculated offline, you need to log the necessary data to use them later. + +### Fault tolerance + +Your application may encounter errors such as exceptions in your model inference or business logic code, causing failures and disrupting traffic. Other potential issues could arise from the machine running your application, such as unexpected hardware breakdowns or loss of spot-instances during high-demand periods. One way to mitigate these risks is by increasing redundancy through replica scaling and implementing recovery mechanisms for failed replicas. However, model replicas aren't the only potential points of failure. It's essential to build resilience against various failures that could occur at any point in your stack. + + +### Zero down time upgrade + +System upgrades are often necessary but can result in service disruptions if not handled correctly. One way to prevent downtime during upgrades is by implementing a smooth transition process from the old version to the new one. Ideally, the new version of your LLM service is deployed, and traffic gradually shifts from the old to the new version, maintaining a constant QPS throughout the process. + + +### Load balancing + +Load balancing, in simple terms, is a technique to distribute work evenly across multiple computers, servers, or other resources to optimize the utilization of the system, maximize throughput, minimize response time, and avoid overload of any single resource. Think of it as a traffic officer directing cars (requests) to different roads (servers) so that no single road becomes too congested. + +There are several strategies for load balancing. For example, one common method is the *Round Robin* strategy, where each request is sent to the next server in line, cycling back to the first when all servers have received a request. This works well when all servers are equally capable. However, if some servers are more powerful than others, you might use a *Weighted Round Robin* or *Least Connections* strategy, where more requests are sent to the more powerful servers, or to those currently handling the fewest active requests. Let's imagine you're running a LLM chain. If your application becomes popular, you could have hundreds or even thousands of users asking questions at the same time. If one server gets too busy (high load), the load balancer would direct new requests to another server that is less busy. This way, all your users get a timely response and the system remains stable. + + + +## Maintaining Cost-Efficiency and Scalability + +Deploying LLM services can be costly, especially when you're handling a large volume of user interactions. Charges by LLM providers are usually based on tokens used, making a chat system inference on these models potentially expensive. However, several strategies can help manage these costs without compromising the quality of the service. + + +### Self-hosting models + +Several smaller and open-source LLMs are emerging to tackle the issue of reliance on LLM providers. Self-hosting allows you to maintain similar quality to LLM provider models while managing costs. The challenge lies in building a reliable, high-performing LLM serving system on your own machines. + +### Resource Management and Auto-Scaling + +Computational logic within your application requires precise resource allocation. For instance, if part of your traffic is served by an OpenAI endpoint and another part by a self-hosted model, it's crucial to allocate suitable resources for each. Auto-scaling—adjusting resource allocation based on traffic—can significantly impact the cost of running your application. This strategy requires a balance between cost and responsiveness, ensuring neither resource over-provisioning nor compromised application responsiveness. + +### Utilizing Spot Instances + +On platforms like AWS, spot instances offer substantial cost savings, typically priced at about a third of on-demand instances. The trade-off is a higher crash rate, necessitating a robust fault-tolerance mechanism for effective use. + +### Independent Scaling + +When self-hosting your models, you should consider independent scaling. For example, if you have two translation models, one fine-tuned for French and another for Spanish, incoming requests might necessitate different scaling requirements for each. + +### Batching requests + +In the context of Large Language Models, batching requests can enhance efficiency by better utilizing your GPU resources. GPUs are inherently parallel processors, designed to handle multiple tasks simultaneously. If you send individual requests to the model, the GPU might not be fully utilized as it's only working on a single task at a time. On the other hand, by batching requests together, you're allowing the GPU to work on multiple tasks at once, maximizing its utilization and improving inference speed. This not only leads to cost savings but can also improve the overall latency of your LLM service. + + +In summary, managing costs while scaling your LLM services requires a strategic approach. Utilizing self-hosting models, managing resources effectively, employing auto-scaling, using spot instances, independently scaling models, and batching requests are key strategies to consider. Open-source libraries such as Ray Serve and BentoML are designed to deal with these complexities. + + + +## Ensuring Rapid Iteration + +The LLM landscape is evolving at an unprecedented pace, with new libraries and model architectures being introduced constantly. Consequently, it's crucial to avoid tying yourself to a solution specific to one particular framework. This is especially relevant in serving, where changes to your infrastructure can be time-consuming, expensive, and risky. Strive for infrastructure that is not locked into any specific machine learning library or framework, but instead offers a general-purpose, scalable serving layer. Here are some aspects where flexibility plays a key role: + +### Model composition + +Deploying systems like LangChain demands the ability to piece together different models and connect them via logic. Take the example of building a natural language input SQL query engine. Querying an LLM and obtaining the SQL command is only part of the system. You need to extract metadata from the connected database, construct a prompt for the LLM, run the SQL query on an engine, collect and feedback the response to the LLM as the query runs, and present the results to the user. This demonstrates the need to seamlessly integrate various complex components built in Python into a dynamic chain of logical blocks that can be served together. + +## Cloud providers + +Many hosted solutions are restricted to a single cloud provider, which can limit your options in today's multi-cloud world. Depending on where your other infrastructure components are built, you might prefer to stick with your chosen cloud provider. + + +## Infrastructure as Code (IaC) + +Rapid iteration also involves the ability to recreate your infrastructure quickly and reliably. This is where Infrastructure as Code (IaC) tools like Terraform, CloudFormation, or Kubernetes YAML files come into play. They allow you to define your infrastructure in code files, which can be version controlled and quickly deployed, enabling faster and more reliable iterations. + + +## CI/CD + +In a fast-paced environment, implementing CI/CD pipelines can significantly speed up the iteration process. They help automate the testing and deployment of your LLM applications, reducing the risk of errors and enabling faster feedback and iteration. diff --git a/docs/versioned_docs/version-0.2.x/guides/productionization/deployments/template_repos.mdx b/docs/versioned_docs/version-0.2.x/guides/productionization/deployments/template_repos.mdx new file mode 100644 index 0000000000000..4a8082864ee44 --- /dev/null +++ b/docs/versioned_docs/version-0.2.x/guides/productionization/deployments/template_repos.mdx @@ -0,0 +1,7 @@ +# LangChain Templates + +For more information on LangChain Templates, visit + +- [LangChain Templates Quickstart](https://github.com/langchain-ai/langchain/blob/master/templates/README.md) +- [LangChain Templates Index](https://github.com/langchain-ai/langchain/blob/master/templates/docs/INDEX.md) +- [Full List of Templates](https://github.com/langchain-ai/langchain/blob/master/templates/) \ No newline at end of file diff --git a/docs/versioned_docs/version-0.2.x/guides/productionization/evaluation/comparison/custom.ipynb b/docs/versioned_docs/version-0.2.x/guides/productionization/evaluation/comparison/custom.ipynb new file mode 100644 index 0000000000000..3b10f833e86b5 --- /dev/null +++ b/docs/versioned_docs/version-0.2.x/guides/productionization/evaluation/comparison/custom.ipynb @@ -0,0 +1,293 @@ +{ + "cells": [ + { + "cell_type": "raw", + "id": "5046d96f-d578-4d5b-9a7e-43b28cafe61d", + "metadata": {}, + "source": [ + "---\n", + "sidebar_position: 2\n", + "title: Custom pairwise evaluator\n", + "---" + ] + }, + { + "cell_type": "markdown", + "id": "657d2c8c-54b4-42a3-9f02-bdefa0ed6728", + "metadata": {}, + "source": [ + "[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/langchain-ai/langchain/blob/master/docs/docs/guides/evaluation/comparison/custom.ipynb)\n", + "\n", + "You can make your own pairwise string evaluators by inheriting from `PairwiseStringEvaluator` class and overwriting the `_evaluate_string_pairs` method (and the `_aevaluate_string_pairs` method if you want to use the evaluator asynchronously).\n", + "\n", + "In this example, you will make a simple custom evaluator that just returns whether the first prediction has more whitespace tokenized 'words' than the second.\n", + "\n", + "You can check out the reference docs for the [PairwiseStringEvaluator interface](https://api.python.langchain.com/en/latest/evaluation/langchain.evaluation.schema.PairwiseStringEvaluator.html#langchain.evaluation.schema.PairwiseStringEvaluator) for more info.\n" + ] + }, + { + "cell_type": "code", + "execution_count": 1, + "id": "93f3a653-d198-4291-973c-8d1adba338b2", + "metadata": { + "tags": [] + }, + "outputs": [], + "source": [ + "from typing import Any, Optional\n", + "\n", + "from langchain.evaluation import PairwiseStringEvaluator\n", + "\n", + "\n", + "class LengthComparisonPairwiseEvaluator(PairwiseStringEvaluator):\n", + " \"\"\"\n", + " Custom evaluator to compare two strings.\n", + " \"\"\"\n", + "\n", + " def _evaluate_string_pairs(\n", + " self,\n", + " *,\n", + " prediction: str,\n", + " prediction_b: str,\n", + " reference: Optional[str] = None,\n", + " input: Optional[str] = None,\n", + " **kwargs: Any,\n", + " ) -> dict:\n", + " score = int(len(prediction.split()) > len(prediction_b.split()))\n", + " return {\"score\": score}" + ] + }, + { + "cell_type": "code", + "execution_count": 2, + "id": "7d4a77c3-07a7-4076-8e7f-f9bca0d6c290", + "metadata": { + "tags": [] + }, + "outputs": [ + { + "data": { + "text/plain": [ + "{'score': 1}" + ] + }, + "execution_count": 2, + "metadata": {}, + "output_type": "execute_result" + } + ], + "source": [ + "evaluator = LengthComparisonPairwiseEvaluator()\n", + "\n", + "evaluator.evaluate_string_pairs(\n", + " prediction=\"The quick brown fox jumped over the lazy dog.\",\n", + " prediction_b=\"The quick brown fox jumped over the dog.\",\n", + ")" + ] + }, + { + "cell_type": "markdown", + "id": "d90f128f-6f49-42a1-b05a-3aea568ee03b", + "metadata": {}, + "source": [ + "## LLM-Based Example\n", + "\n", + "That example was simple to illustrate the API, but it wasn't very useful in practice.

However, +optimizing for metrics alone does not guarantee logically sound reasoning. + +Language models can learn to exploit flaws in reasoning to generate plausible-sounding but logically invalid arguments. When models rely on fallacies, their outputs become unreliable and untrustworthy, even if they achieve high scores on metrics. Users cannot depend on such outputs. Propagating logical fallacies can spread misinformation, confuse users, and lead to harmful real-world consequences when models are deployed in products or services. + +Monitoring and testing specifically for logical flaws is challenging unlike other quality issues. It requires reasoning about arguments rather than pattern matching. + +Therefore, it is crucial that model developers proactively address logical fallacies after optimizing metrics. Specialized techniques like causal modeling, robustness testing, and bias mitigation can help avoid flawed reasoning. Overall, allowing logical flaws to persist makes models less safe and ethical.
