+# Concepts
+
+
+The core idea of agents is to use a language model to choose a sequence of actions to take.
+In chains, a sequence of actions is hardcoded (in code).
+In agents, a language model is used as a reasoning engine to determine which actions to take and in which order.
+
+There are several key components here:
+
+## Schema
+
+LangChain has several abstractions to make working with agents easy.
+
+### AgentAction
+
+This is a dataclass that represents the action an agent should take.
+It has a `tool` property (which is the name of the tool that should be invoked) and a `tool_input` property (the input to that tool)
+
+### AgentFinish
+
+This represents the final result from an agent, when it is ready to return to the user.
+It contains a `return_values` key-value mapping, which contains the final agent output.
+Usually, this contains an `output` key containing a string that is the agent's response.
+
+### Intermediate Steps
+
+These represent previous agent actions and corresponding outputs from this CURRENT agent run.
+These are important to pass to future iteration so the agent knows what work it has already done.
+This is typed as a `List[Tuple[AgentAction, Any]]`.
+Note that observation is currently left as type `Any` to be maximally flexible.
+In practice, this is often a string.
+
+## Agent
+
+This is the chain responsible for deciding what step to take next.
+This is usually powered by a language model, a prompt, and an output parser.
+
+Different agents have different prompting styles for reasoning, different ways of encoding inputs, and different ways of parsing the output.
+For a full list of built-in agents see [agent types](/docs/modules/agents/agent_types/).
+You can also **easily build custom agents**, should you need further control.
+
+### Agent Inputs
+
+The inputs to an agent are a key-value mapping.
+There is only one required key: `intermediate_steps`, which corresponds to `Intermediate Steps` as described above.
+
+Generally, the PromptTemplate takes care of transforming these pairs into a format that can best be passed into the LLM.
+
+### Agent Outputs
+
+The output is the next action(s) to take or the final response to send to the user (`AgentAction`s or `AgentFinish`).
+Concretely, this can be typed as `Union[AgentAction, List[AgentAction], AgentFinish]`.
+
+The output parser is responsible for taking the raw LLM output and transforming it into one of these three types.
+
+## AgentExecutor
+
+The agent executor is the runtime for an agent.
+This is what actually calls the agent, executes the actions it chooses, passes the action outputs back to the agent, and repeats.
+In pseudocode, this looks roughly like:
+
+```python
+next_action = agent.get_action(...)
+while next_action != AgentFinish:
+ observation = run(next_action)
+ next_action = agent.get_action(..., next_action, observation)
+return next_action
+```
+
+While this may seem simple, there are several complexities this runtime handles for you, including:
+
+1. Handling cases where the agent selects a non-existent tool
+2. Handling cases where the tool errors
+3. Handling cases where the agent produces output that cannot be parsed into a tool invocation
+4. Logging and observability at all levels (agent decisions, tool calls) to stdout and/or to [LangSmith](/docs/langsmith).
+
+## Tools
+
+Tools are functions that an agent can invoke.
+The `Tool` abstraction consists of two components:
+
+1. The input schema for the tool. This tells the LLM what parameters are needed to call the tool. Without this, it will not know what the correct inputs are. These parameters should be sensibly named and described.
+2. The function to run. This is generally just a Python function that is invoked.
+
+
+### Considerations
+There are two important design considerations around tools:
+
+1. Giving the agent access to the right tools
+2. Describing the tools in a way that is most helpful to the agent
+
+Without thinking through both, you won't be able to build a working agent.
+If you don't give the agent access to a correct set of tools, it will never be able to accomplish the objectives you give it.
+If you don't describe the tools well, the agent won't know how to use them properly.
+
+LangChain provides a wide set of built-in tools, but also makes it easy to define your own (including custom descriptions).
+For a full list of built-in tools, see the [tools integrations section](/docs/integrations/tools/)
+
+## Toolkits
+
+For many common tasks, an agent will need a set of related tools.
+For this LangChain provides the concept of toolkits - groups of around 3-5 tools needed to accomplish specific objectives.
+For example, the GitHub toolkit has a tool for searching through GitHub issues, a tool for reading a file, a tool for commenting, etc.
+
+LangChain provides a wide set of toolkits to get started.
+For a full list of built-in toolkits, see the [toolkits integrations section](/docs/integrations/toolkits/)

-# Custom LLM Agent
-
-This notebook goes through how to create your own custom LLM agent.
-
-An LLM agent consists of three parts:
-
-- `PromptTemplate`: This is the prompt template that can be used to instruct the language model on what to do
-- LLM: This is the language model that powers the agent
-- `stop` sequence: Instructs the LLM to stop generating as soon as this string is found
-- `OutputParser`: This determines how to parse the LLM output into an `AgentAction` or `AgentFinish` object
-
-The LLM Agent is used in an `AgentExecutor`. This `AgentExecutor` can largely be thought of as a loop that:
-1. Passes user input and any previous steps to the Agent (in this case, the LLM Agent)
-2. If the Agent returns an `AgentFinish`, then return that directly to the user
-3. If the Agent returns an `AgentAction`, then use that to call a tool and get an `Observation`
-4. Repeat, passing the `AgentAction` and `Observation` back to the Agent until an `AgentFinish` is emitted.
-
-`AgentAction` is a response that consists of `action` and `action_input`. `action` refers to which tool to use, and `action_input` refers to the input to that tool. `log` can also be provided as more context (that can be used for logging, tracing, etc).
-
-`AgentFinish` is a response that contains the final message to be sent back to the user. This should be used to end an agent run.
-
-In this notebook we walk through how to create a custom LLM agent.
-
-
-
-## Set up environment
-
-Do necessary imports, etc.
-
-
-```python
-from langchain.agents import Tool, AgentExecutor, LLMSingleActionAgent, AgentOutputParser
-from langchain.prompts import StringPromptTemplate
-from langchain.llms import OpenAI
-from langchain.utilities import SerpAPIWrapper
-from langchain.chains import LLMChain
-from typing import List, Union
-from langchain.schema import AgentAction, AgentFinish, OutputParserException
-import re
-```
-
-## Set up tool
-
-Set up any tools the agent may want to use. This may be necessary to put in the prompt (so that the agent knows to use these tools).
-
-
-```python
-# Define which tools the agent can use to answer user queries
-search = SerpAPIWrapper()
-tools = [
- Tool(
- name="Search",
- func=search.run,
- description="useful for when you need to answer questions about current events"
- )
-]
-```
-
-## Prompt template
-
-This instructs the agent on what to do. Generally, the template should incorporate:
-
-- `tools`: which tools the agent has access and how and when to call them.
-- `intermediate_steps`: These are tuples of previous (`AgentAction`, `Observation`) pairs. These are generally not passed directly to the model, but the prompt template formats them in a specific way.
-- `input`: generic user input
-
-
-```python
-# Set up the base template
-template = """Answer the following questions as best you can, but speaking as a pirate might speak. You have access to the following tools:
-
-{tools}
-
-Use the following format:
-
-Question: the input question you must answer
-Thought: you should always think about what to do
-Action: the action to take, should be one of [{tool_names}]
-Action Input: the input to the action
-Observation: the result of the action
-... (this Thought/Action/Action Input/Observation can repeat N times)
-Thought: I now know the final answer
-Final Answer: the final answer to the original input question
-
-Begin! Remember to speak as a pirate when giving your final answer. Use lots of "Arg"s
-
-Question: {input}
-{agent_scratchpad}"""
-```
-
-
-```python
-# Set up a prompt template
-class CustomPromptTemplate(StringPromptTemplate):
- # The template to use
- template: str
- # The list of tools available
- tools: List[Tool]
-
- def format(self, **kwargs) -> str:
- # Get the intermediate steps (AgentAction, Observation tuples)
- # Format them in a particular way
- intermediate_steps = kwargs.pop("intermediate_steps")
- thoughts = ""
- for action, observation in intermediate_steps:
- thoughts += action.log
- thoughts += f"\nObservation: {observation}\nThought: "
- # Set the agent_scratchpad variable to that value
- kwargs["agent_scratchpad"] = thoughts
- # Create a tools variable from the list of tools provided
- kwargs["tools"] = "\n".join([f"{tool.name}: {tool.description}" for tool in self.tools])
- # Create a list of tool names for the tools provided
- kwargs["tool_names"] = ", ".join([tool.name for tool in self.tools])
- return self.template.format(**kwargs)
-```
-
-
-```python
-prompt = CustomPromptTemplate(
- template=template,
- tools=tools,
- # This omits the `agent_scratchpad`, `tools`, and `tool_names` variables because those are generated dynamically
- # This includes the `intermediate_steps` variable because that is needed
- input_variables=["input", "intermediate_steps"]
-)
-```
-
-## Output parser
-
-The output parser is responsible for parsing the LLM output into `AgentAction` and `AgentFinish`. This usually depends heavily on the prompt used.
-
-This is where you can change the parsing to do retries, handle whitespace, etc.
-
-
-```python
-class CustomOutputParser(AgentOutputParser):
-
- def parse(self, llm_output: str) -> Union[AgentAction, AgentFinish]:
- # Check if agent should finish
- if "Final Answer:" in llm_output:
- return AgentFinish(
- # Return values is generally always a dictionary with a single `output` key
- # It is not recommended to try anything else at the moment :)
- return_values={"output": llm_output.split("Final Answer:")[-1].strip()},
- log=llm_output,
- )
- # Parse out the action and action input
- regex = r"Action\s*\d*\s*:(.*?)\nAction\s*\d*\s*Input\s*\d*\s*:[\s]*(.*)"
- match = re.search(regex, llm_output, re.DOTALL)
- if not match:
- raise OutputParserException(f"Could not parse LLM output: `{llm_output}`")
- action = match.group(1).strip()
- action_input = match.group(2)
- # Return the action and action input
- return AgentAction(tool=action, tool_input=action_input.strip(" ").strip('"'), log=llm_output)
-```
-
-
-```python
-output_parser = CustomOutputParser()
-```
-
-## Set up LLM
-
-Choose the LLM you want to use!
-
-
-```python
-llm = OpenAI(temperature=0)
-```
-
-## Define the stop sequence
-
-This is important because it tells the LLM when to stop generation.
-
-This depends heavily on the prompt and model you are using. Generally, you want this to be whatever token you use in the prompt to denote the start of an `Observation` (otherwise, the LLM may hallucinate an observation for you).
-
-## Set up the Agent
-
-We can now combine everything to set up our agent:
-
-
-```python
-# LLM chain consisting of the LLM and a prompt
-llm_chain = LLMChain(llm=llm, prompt=prompt)
-```
-
-
-```python
-tool_names = [tool.name for tool in tools]
-agent = LLMSingleActionAgent(
- llm_chain=llm_chain,
- output_parser=output_parser,
- stop=["\nObservation:"],
- allowed_tools=tool_names
-)
-```
-
-## Use the Agent
-
-Now we can use it!
-
-
-```python
-agent_executor = AgentExecutor.from_agent_and_tools(agent=agent, tools=tools, verbose=True)
-```
-
-
-```python
-agent_executor.run("How many people live in canada as of 2023?")

-
- > Finished chain.
-
-
-
-
-
- "Arrr, there be 38,658,314 people livin' in Canada as of 2023!"
-```
-
-
-
-## Adding Memory
-
-If you want to add memory to the agent, you'll need to:
-
-1. Add a place in the custom prompt for the `chat_history`
-2. Add a memory object to the agent executor.
-
-
-```python
-# Set up the base template
-template_with_history = """Answer the following questions as best you can, but speaking as a pirate might speak. You have access to the following tools:

-# Replicating MRKL
-
-This walkthrough demonstrates how to replicate the [MRKL](https://arxiv.org/pdf/2205.00445.pdf) system using agents.
-
-This uses the example Chinook database.
-To set it up, follow the instructions on https://database.guide/2-sample-databases-sqlite/ and place the `.db` file in a "notebooks" folder at the root of this repository.

"In chains, a sequence of actions is hardcoded (in code).\n",
"In agents, a language model is used as a reasoning engine to determine which actions to take and in which order.\n",

- "## Concepts\n",
- "There are several key components here:\n",
+ "## [Quick Start](/docs/modules/agents/quick_start)\n",
"\n",
- "### Agent\n",
+ "For a quick start to working with agents, please check out [this getting started guide](/docs/modules/agents/quick_start). This covers basics like initializing an agent, creating tools, and adding memory.\n",
"\n",
- "This is the chain responsible for deciding what step to take next.\n",
- "This is powered by a language model and a prompt.\n",
- "The inputs to this chain are:\n",
+ "## [Concepts](/docs/modules/agents/concepts)\n",
"\n",
- "1. Tools: Descriptions of available tools\n",
- "2. User input: The high level objective\n",
- "3. Intermediate steps: Any (action, tool output) pairs previously executed in order to achieve the user input\n",
+ "There are several key concepts to understand when building agents: Agents, AgentExecutor, Tools, Toolkits.\n",
+ "For an in depth explanation, please check out [this conceptual guide](/docs/modules/agents/concepts)\n",
"\n",
- "The output is the next action(s) to take or the final response to send to the user (`AgentAction`s or `AgentFinish`). An action specifies a tool and the input to that tool. \n",
"\n",
- "Different agents have different prompting styles for reasoning, different ways of encoding inputs, and different ways of parsing the output.\n",
- "For a full list of built-in agents see [agent types](/docs/modules/agents/agent_types/).\n",
- "You can also **easily build custom agents**, which we show how to do in the Get started section below.\n",
+ "## [Agent Types](/docs/modules/agents/agent_types/)\n",
"\n",
- "### Tools\n",
+ "There are many different types of agents to use. For a overview of the different types and when to use them, please check out [this section](/docs/modules/agents/agent_types/).\n",
"\n",
- "Tools are functions that an agent can invoke.\n",
- "There are two important design considerations around tools:\n",
+ "## [Tools](/docs/modules/agents/tools/)\n",
"\n",
- "1. Giving the agent access to the right tools\n",
- "2. Describing the tools in a way that is most helpful to the agent\n",
+ "Agents are only as good as the tools they have. For a comprehensive guide on tools, please see [this section](/docs/modules/agents/tools/).\n",
"\n",
- "Without thinking through both, you won't be able to build a working agent.\n",
- "If you don't give the agent access to a correct set of tools, it will never be able to accomplish the objectives you give it.\n",
- "If you don't describe the tools well, the agent won't know how to use them properly.\n",
+ "## How To Guides\n",
"\n",
- "LangChain provides a wide set of built-in tools, but also makes it easy to define your own (including custom descriptions).\n",
- "For a full list of built-in tools, see the [tools integrations section](/docs/integrations/tools/)\n",
+ "Agents have a lot of related functionality! Check out comprehensive guides including:\n",
"\n",
- "### Toolkits\n",
- "\n",
- "For many common tasks, an agent will need a set of related tools.\n",
- "For this LangChain provides the concept of toolkits - groups of around 3-5 tools needed to accomplish specific objectives.\n",
- "For example, the GitHub toolkit has a tool for searching through GitHub issues, a tool for reading a file, a tool for commenting, etc.\n",
- "\n",
- "LangChain provides a wide set of toolkits to get started.\n",
- "For a full list of built-in toolkits, see the [toolkits integrations section](/docs/integrations/toolkits/)\n",
- "\n",
- "### AgentExecutor\n",
- "\n",
- "The agent executor is the runtime for an agent.\n",
- "This is what actually calls the agent, executes the actions it chooses, passes the action outputs back to the agent, and repeats.\n",
- "In pseudocode, this looks roughly like:\n",
- "\n",
- "```python\n",
- "next_action = agent.get_action(...)\n",
- "while next_action != AgentFinish:\n",
- " observation = run(next_action)\n",
- " next_action = agent.get_action(..., next_action, observation)\n",
- "return next_action\n",
- "```\n",
- "\n",
- "While this may seem simple, there are several complexities this runtime handles for you, including:\n",
- "\n",
- "1. Handling cases where the agent selects a non-existent tool\n",
- "2. Handling cases where the tool errors\n",
- "3. Handling cases where the agent produces output that cannot be parsed into a tool invocation\n",
- "4. Logging and observability at all levels (agent decisions, tool calls) to stdout and/or to [LangSmith](/docs/langsmith).\n",
- "\n",
- "### Other types of agent runtimes\n",
- "\n",
- "The `AgentExecutor` class is the main agent runtime supported by LangChain.\n",
- "However, there are other, more experimental runtimes we also support.\n",
- "These include:\n",
- "\n",
- "- [Plan-and-execute Agent](/docs/use_cases/more/agents/autonomous_agents/plan_and_execute)\n",
- "- [Baby AGI](/docs/use_cases/more/agents/autonomous_agents/baby_agi)\n",
- "- [Auto GPT](/docs/use_cases/more/agents/autonomous_agents/autogpt)\n",
- "\n",
- "You can also always create your own custom execution logic, which we show how to do below.\n",
- "\n",
- "## Get started\n",
- "\n",
- "To best understand the agent framework, lets build an agent from scratch using LangChain Expression Language (LCEL).\n",
- "We'll need to build the agent itself, define custom tools, and run the agent and tools in a custom loop. At the end we'll show how to use the standard LangChain `AgentExecutor` to make execution easier.\n",
- "\n",
- "Some important terminology (and schema) to know:\n",
- "\n",
- "1. `AgentAction`: This is a dataclass that represents the action an agent should take. It has a `tool` property (which is the name of the tool that should be invoked) and a `tool_input` property (the input to that tool)\n",
- "2. `AgentFinish`: This is a dataclass that signifies that the agent has finished and should return to the user. It has a `return_values` parameter, which is a dictionary to return. It often only has one key - `output` - that is a string, and so often it is just this key that is returned.\n",
- "3. `intermediate_steps`: These represent previous agent actions and corresponding outputs that are passed around. These are important to pass to future iteration so the agent knows what work it has already done. This is typed as a `List[Tuple[AgentAction, Any]]`. Note that observation is currently left as type `Any` to be maximally flexible. In practice, this is often a string.\n",
- "\n",
- "### Setup: LangSmith\n",
- "\n",
- "By definition, agents take a self-determined, input-dependent sequence of steps before returning a user-facing output. This makes debugging these systems particularly tricky, and observability particularly important. [LangSmith](/docs/langsmith) is especially useful for such cases.\n",
- "\n",
- "When building with LangChain, any built-in agent or custom agent built with LCEL will automatically be traced in LangSmith. And if we use the `AgentExecutor`, we'll get full tracing of not only the agent planning steps but also the tool inputs and outputs.\n",
- "\n",
- "To set up LangSmith we just need set the following environment variables:\n",
- "\n",
- "```bash\n",
- "export LANGCHAIN_TRACING_V2=\"true\"\n",
- "export LANGCHAIN_API_KEY=\"\"\n",
- "```\n",
- "\n",
- "### Define the agent\n",
- "\n",
- "We first need to create our agent.\n",
- "This is the chain responsible for determining what action to take next.\n",
- "\n",
- "In this example, we will use OpenAI Function Calling to create this agent.\n",
- "**This is generally the most reliable way to create agents.**\n",
- "\n",
- "For this guide, we will construct a custom agent that has access to a custom tool.\n",
- "We are choosing this example because for most real world use cases you will NEED to customize either the agent or the tools. \n",
- "We'll create a simple tool that computes the length of a word.\n",
- "This is useful because it's actually something LLMs can mess up due to tokenization.\n",
- "We will first create it WITHOUT memory, but we will then show how to add memory in.\n",
- "Memory is needed to enable conversation.\n",
- "\n",
- "First, let's load the language model we're going to use to control the agent."

The most basic approach is to run the chain over the data points and visualize the outputs. Despite technological advancements, there still is no substitute for looking at outputs by eye. Currently, running the chain over the data points needs to be done client-side. The LangSmith client makes it easy to pull down a dataset and then run a chain over them, logging the results to a new project associated with the dataset. From there, you can review them. We've made it easy to assign feedback to runs and mark them as correct or incorrect directly in the web app, displaying aggregate statistics for each test project.We also make it easier to evaluate these runs. To that end, we've added a set of evaluators to the open-source LangChain library. These evaluators can be specified when initiating a test run and will evaluate the results once the test run completes.

-
-Tools are interfaces that an agent can use to interact with the world.
-
-## Getting Started
-
-Tools are functions that agents can use to interact with the world.
-These tools can be generic utilities (e.g. search), other chains, or even other agents.
-
-Currently, tools can be loaded using the following snippet:
-
-```python
-from langchain.agents import load_tools
-tool_names = [...]
-tools = load_tools(tool_names)
-```
-
-Some tools (e.g. chains, agents) may require a base LLM to use to initialize them.
-In that case, you can pass in an LLM as well:
-
-```python
-from langchain.agents import load_tools
-tool_names = [...]
-llm = ...
-tools = load_tools(tool_names, llm=llm)
-```

# Toolkits
-:::info
-For documentation on built-in toolkit integrations, visit [Integrations](/docs/integrations/toolkits/).
-:::
Toolkits are collections of tools that are designed to be used together for specific tasks and have convenient loading methods.
+For a complete list of these, 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)
+```

+# Text Splitters
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.
-## Text splitters
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.
@@ -28,68 +23,35 @@ That means there are two different axes along which you can customize your text
1. How the text is split
2. How the chunk size is measured
-### Get started with text splitters
-
-The default recommended text splitter is the RecursiveCharacterTextSplitter. This text splitter takes a list of characters. It tries to create chunks based on splitting on the first character, but if any chunks are too large it then moves onto the next character, and so forth. By default the characters it tries to split on are `["\n\n", "\n", " ", ""]`
-
-In addition to controlling which characters you can split on, you can also control a few other things:
-
-- `length_function`: how the length of chunks is calculated. Defaults to just counting number of characters, but it's pretty common to pass a token counter here.
-- `chunk_size`: the maximum size of your chunks (as measured by the length function).
-- `chunk_overlap`: the maximum overlap between chunks. It can be nice to have some overlap to maintain some continuity between chunks (e.g. do a sliding window).
-- `add_start_index`: whether to include the starting position of each chunk within the original document in the metadata.
+## Types of Text Splitters
-```python
-# This is a long document we can split up.
-with open('../../state_of_the_union.txt') as f:
- state_of_the_union = f.read()
-```
+LangChain offers many different types of text splitters. Below is a table listing all of them, along with a few characteristics:
+**Name**: Name of the text splitter
-```python
-from langchain.text_splitter import RecursiveCharacterTextSplitter
-```
+**Splits On**: How this text splitter splits text
+**Adds Metadata**: Whether or not this text splitter adds metadata about where each chunk came from.
-```python
-text_splitter = RecursiveCharacterTextSplitter(
- # Set a really small chunk size, just to show.
- chunk_size = 100,
- chunk_overlap = 20,
- length_function = len,
- add_start_index = True,
-)
-```
+**Description**: Description of the splitter, including recommendation on when to use it.
-```python
-texts = text_splitter.create_documents([state_of_the_union])
-print(texts[0])
-print(texts[1])
-```
+| Name | Splits On | Adds Metadata | Description |
+|-----------|---------------------------------------|---------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| Recursive | A list of user defined characters | | Recursively splits text. Splitting text recursively serves the purpose of trying to keep related pieces of text next to each other. This is the recommended way to start splitting text. |
+| HTML | HTML specific characters | ✅ | Splits text based on HTML-specific characters. Notably, this adds in relevant information about where that chunk came from (based on the HTML) |
+| Markdown | Markdown specific characters | ✅ | Splits text based on Markdown-specific characters. Notably, this adds in relevant information about where that chunk came from (based on the Markdown) |
+| Code | Code (Python, JS) specific characters | | Splits text based on characters specific to coding languages. 15 different languages are available to choose from. |
+| Token | Tokens | | Splits text on tokens. There exist a few different ways to measure tokens. |
+| Character | A user defined character | | Splits text based on a user defined character. One of the simpler methods. |

-```
- page_content='Madam Speaker, Madam Vice President, our First Lady and Second Gentleman. Members of Congress and' metadata={'start_index': 0}
- page_content='of Congress and the Cabinet. Justices of the Supreme Court. My fellow Americans.' metadata={'start_index': 82}
-```

-### Evaluate text splitters
+## Evaluate text splitters
You can evaluate text splitters with the [Chunkviz utility](https://www.chunkviz.com/) created by `Greg Kamradt`.
`Chunkviz` is a great tool for visualizing how your text splitter is working. It will show you how your text is
being split up and help in tuning up the splitting parameters.
+## Other Document Transforms
-## Other transformations:
-### Filter redundant docs, translate docs, extract metadata, and more
-
-We can do perform a number of transformations on docs which are not simply splitting the text. With the
-`EmbeddingsRedundantFilter` we can identify similar documents and filter out redundancies. With integrations like
-[doctran](https://github.com/psychic-api/doctran/tree/main) we can do things like translate documents from one language
-to another, extract desired properties and add them to metadata, and convert conversational dialogue into a Q/A format
-set of documents.
+Text splitting is only one example of transformations that you may want to do on documents before passing them to an LLM. Head to [Integrations](/docs/integrations/document_transformers/) for documentation on built-in document transformer integrations with 3rd-party tools.

-# Split by character
-
-This is the simplest method. This splits based on characters (by default "\n\n") and measure chunk length by number of characters.
-
-1. How the text is split: by single character.
-2. How the chunk size is measured: by number of characters.
-
-```python
-# This is a long document we can split up.
-with open('../../../state_of_the_union.txt') as f:
- state_of_the_union = f.read()

-```python
-from langchain.text_splitter import CharacterTextSplitter
-text_splitter = CharacterTextSplitter(
- separator = "\n\n",
- chunk_size = 1000,
- chunk_overlap = 200,
- length_function = len,
- is_separator_regex = False,
-)
-```
-

-Large language models (LLMs) are a type of machine learning model that can be trained on vast amounts of text data to generate human-like language. In recent years, LLMs have made significant advances in a variety of natural language processing tasks, including language translation, text generation, and sentiment analysis.
-
-\subsection{History of LLMs}
-The earliest LLMs were developed in the 1980s and 1990s, but they were limited by the amount of data that could be processed and the computational power available at the time. In the past decade, however, advances in hardware and software have made it possible to train LLMs on massive datasets, leading to significant improvements in performance.
-
-\subsection{Applications of LLMs}
-LLMs have many applications in industry, including chatbots, content creation, and virtual assistants. They can also be used in academia for research in linguistics, psychology, and computational linguistics.

-# Recursively split by character
-
-This text splitter is the recommended one for generic text. It is parameterized by a list of characters. It tries to split on them in order until the chunks are small enough. The default list is `["\n\n", "\n", " ", ""]`. This has the effect of trying to keep all paragraphs (and then sentences, and then words) together as long as possible, as those would generically seem to be the strongest semantically related pieces of text.

-# Contextual compression
-
-One challenge with retrieval is that usually you don't know the specific queries your document storage system will face when you ingest data into the system. This means that the information most relevant to a query may be buried in a document with a lot of irrelevant text. Passing that full document through your application can lead to more expensive LLM calls and poorer responses.
-
-Contextual compression is meant to fix this. The idea is simple: instead of immediately returning retrieved documents as-is, you can compress them using the context of the given query, so that only the relevant information is returned. “Compressing” here refers to both compressing the contents of an individual document and filtering out documents wholesale.
-
-To use the Contextual Compression Retriever, you'll need:
-- a base retriever
-- a Document Compressor
-
-The Contextual Compression Retriever passes queries to the base retriever, takes the initial documents and passes them through the Document Compressor. The Document Compressor takes a list of documents and shortens it by reducing the contents of documents or dropping documents altogether.
-
-
-
-## Get started
-
-```python
-# Helper function for printing docs
-
-def pretty_print_docs(docs):
- print(f"\n{'-' * 100}\n".join([f"Document {i+1}:\n\n" + d.page_content for i, d in enumerate(docs)]))
-```
-
-## Using a vanilla vector store retriever
-Let's start by initializing a simple vector store retriever and storing the 2023 State of the Union speech (in chunks). We can see that given an example question our retriever returns one or two relevant docs and a few irrelevant docs. And even the relevant docs have a lot of irrelevant information in them.
-
-
-```python
-from langchain.text_splitter import CharacterTextSplitter
-from langchain.embeddings import OpenAIEmbeddings
-from langchain.document_loaders import TextLoader
-from langchain.vectorstores import FAISS
-
-documents = TextLoader('../../../state_of_the_union.txt').load()
-text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
-texts = text_splitter.split_documents(documents)
-retriever = FAISS.from_documents(texts, OpenAIEmbeddings()).as_retriever()
-
-docs = retriever.get_relevant_documents("What did the president say about Ketanji Brown Jackson")
-pretty_print_docs(docs)
-```

-
- And as Wall Street firms take over more nursing homes, quality in those homes has gone down and costs have gone up.
-
- That ends on my watch.
-
- Medicare is going to set higher standards for nursing homes and make sure your loved ones get the care they deserve and expect.
-
- We’ll also cut costs and keep the economy going strong by giving workers a fair shot, provide more training and apprenticeships, hire them based on their skills not degrees.
-
- Let’s pass the Paycheck Fairness Act and paid leave.
-
- Raise the minimum wage to $15 an hour and extend the Child Tax Credit, so no one has to raise a family in poverty.
-
- Let’s increase Pell Grants and increase our historic support of HBCUs, and invest in what Jill—our First Lady who teaches full-time—calls America’s best-kept secret: community colleges.

-## Adding contextual compression with an `LLMChainExtractor`
-Now let's wrap our base retriever with a `ContextualCompressionRetriever`. We'll add an `LLMChainExtractor`, which will iterate over the initially returned documents and extract from each only the content that is relevant to the query.
-
-
-```python
-from langchain.llms import OpenAI
-from langchain.retrievers import ContextualCompressionRetriever
-from langchain.retrievers.document_compressors import LLMChainExtractor
-
-llm = OpenAI(temperature=0)
-compressor = LLMChainExtractor.from_llm(llm)
-compression_retriever = ContextualCompressionRetriever(base_compressor=compressor, base_retriever=retriever)
-
-compressed_docs = compression_retriever.get_relevant_documents("What did the president say about Ketanji Jackson Brown")
-pretty_print_docs(compressed_docs)
-```
-
-

-```

-## More built-in compressors: filters
-### `LLMChainFilter`
-The `LLMChainFilter` is slightly simpler but more robust compressor that uses an LLM chain to decide which of the initially retrieved documents to filter out and which ones to return, without manipulating the document contents.
-
-

-
-_filter = LLMChainFilter.from_llm(llm)
-compression_retriever = ContextualCompressionRetriever(base_compressor=_filter, base_retriever=retriever)

-
-### `EmbeddingsFilter`
-
-Making an extra LLM call over each retrieved document is expensive and slow. The `EmbeddingsFilter` provides a cheaper and faster option by embedding the documents and query and only returning those documents which have sufficiently similar embeddings to the query.
-
-
-```python
-from langchain.embeddings import OpenAIEmbeddings
-from langchain.retrievers.document_compressors import EmbeddingsFilter
-
-embeddings = OpenAIEmbeddings()
-embeddings_filter = EmbeddingsFilter(embeddings=embeddings, similarity_threshold=0.76)
-compression_retriever = ContextualCompressionRetriever(base_compressor=embeddings_filter, base_retriever=retriever)
-
-compressed_docs = compression_retriever.get_relevant_documents("What did the president say about Ketanji Jackson Brown")
-pretty_print_docs(compressed_docs)

-# Stringing compressors and document transformers together
-Using the `DocumentCompressorPipeline` we can also easily combine multiple compressors in sequence. Along with compressors we can add `BaseDocumentTransformer`s to our pipeline, which don't perform any contextual compression but simply perform some transformation on a set of documents. For example `TextSplitter`s can be used as document transformers to split documents into smaller pieces, and the `EmbeddingsRedundantFilter` can be used to filter out redundant documents based on embedding similarity between documents.
-
-Below we create a compressor pipeline by first splitting our docs into smaller chunks, then removing redundant documents, and then filtering based on relevance to the query.
-
-
-```python
-from langchain.document_transformers import EmbeddingsRedundantFilter
-from langchain.retrievers.document_compressors import DocumentCompressorPipeline
-from langchain.text_splitter import CharacterTextSplitter
-
-splitter = CharacterTextSplitter(chunk_size=300, chunk_overlap=0, separator=". ")
-redundant_filter = EmbeddingsRedundantFilter(embeddings=embeddings)
-relevant_filter = EmbeddingsFilter(embeddings=embeddings, similarity_threshold=0.76)
-pipeline_compressor = DocumentCompressorPipeline(
- transformers=[splitter, redundant_filter, relevant_filter]
-)
-```
-
-
-```python
-compression_retriever = ContextualCompressionRetriever(base_compressor=pipeline_compressor, base_retriever=retriever)
-
-compressed_docs = compression_retriever.get_relevant_documents("What did the president say about Ketanji Jackson Brown")
-pretty_print_docs(compressed_docs)
-```
-
-
-
-```
- Document 1:
-
- One of the most serious constitutional responsibilities a President has is nominating someone to serve on the United States Supreme Court.
-
- And I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson
- ----------------------------------------------------------------------------------------------------
- Document 2:
-
- As I said last year, especially to our younger transgender Americans, I will always have your back as your President, so you can be yourself and reach your God-given potential.
-
- While it often appears that we never agree, that isn’t true. I signed 80 bipartisan bills into law last year
- ----------------------------------------------------------------------------------------------------
- Document 3:
-
- A former top litigator in private practice. A former federal public defender. And from a family of public school educators and police officers. A consensus builder

+# 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. Vector stores can be used
+as the backbone of a retriever, but there are other types of retrievers as well.
+
+Retrievers accept a string query as input and return a list of `Document`'s as output.
+
+## Advanced Retrieval Types
+
+LangChain provides several advanced retrieval types. A full list is below, along with the following information:
+
+**Name**: Name of the retrieval algorithm.
+
+**Index Type**: Which index type (if any) this relies on.
+
+**Uses an LLM**: Whether this retrieval method uses an LLM.
+
+**When to Use**: Our commentary on when you should considering using this retrieval method.
+
+**Description**: Description of what this retrieval algorithm is doing.
+
+| Name | Index Type | Uses an LLM | When to Use | Description |
+|---------------------------|------------------------------|---------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| [Vectorstore](./vectorstore) | Vectorstore | No | If you are just getting started and looking for something quick and easy. | This is the simplest method and the one that is easiest to get started with. It involves creating embeddings for each piece of text. |
+| [ParentDocument](./parent_document_retriever) | Vectorstore + Document Store | No | If your pages have lots of smaller pieces of distinct information that are best indexed by themselves, but best retrieved all together. | This involves indexing multiple chunks for each document. Then you find the chunks that are most similar in embedding space, but you retrieve the whole parent document and return that (rather than individual chunks). |
+| [Multi Vector](multi_vector) | Vectorstore + Document Store | Sometimes during indexing | If you are able to extract information from documents that you think is more relevant to index than the text itself. | This involves creating multiple vectors for each document. Each vector could be created in a myriad of ways - examples include summaries of the text and hypothetical questions. |
+| [Self Query](./self_query) | Vectorstore | Yes | If users are asking questions that are better answered by fetching documents based on metadata rather than similarity with the text. | This uses an LLM to transform user input into two things: (1) a string to look up semantically, (2) a metadata filer to go along with it. This is useful because oftentimes questions are about the METADATA of documents (not the content itself). |
+| [Contextual Compression](./contextual_compression) | Any | Sometimes | If you are finding that your retrieved documents contain too much irrelevant information and are distracting the LLM. | This puts a post-processing step on top of another retriever and extracts only the most relevant information from retrieved documents. This can be done with embeddings or an LLM. |
+| [Time-Weighted Vectorstore](./time_weighted_vectorstore) | Vectorstore | No | If you have timestamps associated with your documents, and you want to retrieve the most recent ones | This fetches documents based on a combination of semantic similarity (as in normal vector retrieval) and recency (looking at timestamps of indexed documents) |
+| [Multi-Query Retriever](./MultiQueryRetriever) | Any | Yes | If users are asking questions that are complex and require multiple pieces of distinct information to respond | This uses an LLM to generate multiple queries from the original one. This is useful when the original query needs pieces of information about multiple topics to be properly answered. By generating multiple queries, we can then fetch documents for each of them. |
+| [Ensemble](./ensemble) | Any | No | If you have multiple retrieval methods and want to try combining them. | This fetches documents from multiple retrievers and then combines them. |
+| [Long-Context Reorder](./long_context_reorder) | Any | No | If you are working with a long-context model and noticing that it's not paying attention to information in the middle of retrieved documents. | This fetches documents from an underlying retriever, and then reorders them so that the most similar are near the beginning and end. This is useful because it's been shown that for longer context models they sometimes don't pay attention to information in the middle of the context window. |
+
+
+## [Third Party Integrations](/docs/integrations/retrievers/)
+
+LangChain also integrates with many third-party retrieval services. For a full list of these, check out [this list](/docs/integrations/retrievers/) of all integrations.
+
+## Using Retrievers in LCEL
+
+Since retrievers are `Runnable`'s, we can easily compose them with other `Runnable` objects:
+
+```python
+from langchain.chat_models import ChatOpenAI
+from langchain.prompts import ChatPromptTemplate
+from langchain.schema import StrOutputParser
+from langchain_core.runnables import RunnablePassthrough
+
+template = """Answer the question based only on the following context:
+
+{context}
+
+Question: {question}
+"""
+prompt = ChatPromptTemplate.from_template(template)
+model = ChatOpenAI()
+
+
+def format_docs(docs):
+ return "\n\n".join([d.page_content for d in docs])
+
+
+chain = (
+ {"context": retriever | format_docs, "question": RunnablePassthrough()}
+ | prompt
+ | model
+ | StrOutputParser()
+)
+
+chain.invoke("What did the president say about technology?")
+
+```
+
+## Custom Retriever
+
+Since the retriever interface is so simple, it's pretty easy to write a custom one.
+
+```python
+from langchain_core.retrievers import BaseRetriever
+from langchain_core.callbacks import CallbackManagerForRetrieverRun
+from langchain_core.documents import Document
+from typing import List
+
+
+class CustomRetriever(BaseRetriever):
+
+ def _get_relevant_documents(
+ self, query: str, *, run_manager: CallbackManagerForRetrieverRun
+ ) -> List[Document]:
+ return [Document(page_content=query)]
+
+retriever = CustomRetriever()
+
+retriever.get_relevant_documents("bar")
+```

-# Time-weighted vector store retriever
-
-This retriever uses a combination of semantic similarity and a time decay.
-
-The algorithm for scoring them is:
-
-```
-semantic_similarity + (1.0 - decay_rate) ^ hours_passed
-```
-
-Notably, `hours_passed` refers to the hours passed since the object in the retriever **was last accessed**, not since it was created. This means that frequently accessed objects remain "fresh".
-
-```python
-import faiss
-
-from datetime import datetime, timedelta
-from langchain.docstore import InMemoryDocstore
-from langchain.embeddings import OpenAIEmbeddings
-from langchain.retrievers import TimeWeightedVectorStoreRetriever
-from langchain.schema import Document
-from langchain.vectorstores import FAISS
-```
-
-## Low decay rate
-
-A low `decay rate` (in this, to be extreme, we will set it close to 0) means memories will be "remembered" for longer. A `decay rate` of 0 means memories never be forgotten, making this retriever equivalent to the vector lookup.
-
-
-```python
-# Define your embedding model
-embeddings_model = OpenAIEmbeddings()
-# Initialize the vectorstore as empty
-embedding_size = 1536
-index = faiss.IndexFlatL2(embedding_size)
-vectorstore = FAISS(embeddings_model.embed_query, index, InMemoryDocstore({}), {})
-retriever = TimeWeightedVectorStoreRetriever(vectorstore=vectorstore, decay_rate=.0000000000000000000000001, k=1)
-```
-
-
-```python
-yesterday = datetime.now() - timedelta(days=1)
-retriever.add_documents([Document(page_content="hello world", metadata={"last_accessed_at": yesterday})])
-retriever.add_documents([Document(page_content="hello foo")])
-```
-
-
-
-```
- ['d7f85756-2371-4bdf-9140-052780a0f9b3']
-```
-
-
-
-
-```python
-# "Hello World" is returned first because it is most salient, and the decay rate is close to 0., meaning it's still recent enough
-retriever.get_relevant_documents("hello world")
-```
-
-
-
-```
- [Document(page_content='hello world', metadata={'last_accessed_at': datetime.datetime(2023, 5, 13, 21, 0, 27, 678341), 'created_at': datetime.datetime(2023, 5, 13, 21, 0, 27, 279596), 'buffer_idx': 0})]
-```
-
-
-
-## High decay rate
-
-With a high `decay rate` (e.g., several 9's), the `recency score` quickly goes to 0! If you set this all the way to 1, `recency` is 0 for all objects, once again making this equivalent to a vector lookup.
-
-
-
-```python
-# Define your embedding model
-embeddings_model = OpenAIEmbeddings()
-# Initialize the vectorstore as empty
-embedding_size = 1536
-index = faiss.IndexFlatL2(embedding_size)
-vectorstore = FAISS(embeddings_model.embed_query, index, InMemoryDocstore({}), {})

-retriever.add_documents([Document(page_content="hello foo")])

-retriever.get_relevant_documents("hello world")
-```

- [Document(page_content='hello foo', metadata={'last_accessed_at': datetime.datetime(2023, 4, 16, 22, 9, 2, 494798), 'created_at': datetime.datetime(2023, 4, 16, 22, 9, 2, 178722), 'buffer_idx': 1})]
-```
-
-
-
-## Virtual time
-
-Using some utils in LangChain, you can mock out the time component.
-
-
-```python
-from langchain.utils import mock_now
-import datetime
-```
-
-
-```python
-# Notice the last access time is that date time
-with mock_now(datetime.datetime(2011, 2, 3, 10, 11)):
- print(retriever.get_relevant_documents("hello world"))
-```
-
-
-
-```

-# Vector store-backed retriever
-
-A vector store retriever is a retriever that uses a vector store to retrieve documents. It is a lightweight wrapper around the vector store class to make it conform to the retriever interface.
-It uses the search methods implemented by a vector store, like similarity search and MMR, to query the texts in the vector store.
-
-Once you construct a vector store, it's very easy to construct a retriever. Let's walk through an example.
-
-```python
-from langchain.document_loaders import TextLoader
-loader = TextLoader('../../../state_of_the_union.txt')
-```
-
-
-```python
-from langchain.text_splitter import CharacterTextSplitter
-from langchain.vectorstores import FAISS
-from langchain.embeddings import OpenAIEmbeddings
-
-documents = loader.load()
-text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
-texts = text_splitter.split_documents(documents)
-embeddings = OpenAIEmbeddings()
-db = FAISS.from_documents(texts, embeddings)
-```

-
-```python
-retriever = db.as_retriever()
-```
-
-
-```python
-docs = retriever.get_relevant_documents("what did he say about ketanji brown jackson")
-```
-
-## Maximum marginal relevance retrieval
-By default, the vector store retriever uses similarity search. If the underlying vector store supports maximum marginal relevance search, you can specify that as the search type.
-
-
-```python
-retriever = db.as_retriever(search_type="mmr")
-```
-
-
-```python
-docs = retriever.get_relevant_documents("what did he say about ketanji brown jackson")
-```
-
-## Similarity score threshold retrieval
-
-You can also set a retrieval method that sets a similarity score threshold and only returns documents with a score above that threshold.
-
-
-```python
-retriever = db.as_retriever(search_type="similarity_score_threshold", search_kwargs={"score_threshold": .5})
-```
-
-
-```python
-docs = retriever.get_relevant_documents("what did he say about ketanji brown jackson")
-```

+# Chat Models
+
+ChatModels are a core component of LangChain.
+LangChain does not serve its own ChatModels, but rather provides a standard interface for interacting with many different models. To be specific, this interface is one that takes as input a list of messages and returns a message.
+
+
+There are lots of model providers (OpenAI, Cohere, Hugging Face, etc) - the `ChatModel` class is designed to provide a standard interface for all of them.
+
+## [Quick Start](./quick_start)
+
+Check out [this quick start](./quick_start) to get an overview of working with ChatModels, including all the different methods they expose
+
+## [Integrations](/docs/integrations/chat/)
+
+For a full list of all LLM integrations that LangChain provides, please go to the [Integrations page](/docs/integrations/chat/)
+
+## How-To Guides
+
+We have several how-to guides for more advanced usage of LLMs.
+This includes:
+
+- [How to cache ChatModel responses](./chat_model_caching)
+- [How to stream responses from a ChatModel](./streaming)
+- [How to track token usage in a ChatModel call)(./token_usage_tracking)

-# Prompts
-
-Prompts for chat models are built around messages, instead of just plain text.
-
-You can make use of templating by using a `MessagePromptTemplate`. You can build a `ChatPromptTemplate` from one or more `MessagePromptTemplates`. You can use `ChatPromptTemplate`'s `format_prompt` -- this returns a `PromptValue`, which you can convert to a string or Message object, depending on whether you want to use the formatted value as input to an llm or chat model.
-
-For convenience, there is a `from_template` method defined on the template. If you were to use this template, this is what it would look like:
-
-
-```python
-from langchain.prompts import PromptTemplate
-from langchain.prompts.chat import (
- ChatPromptTemplate,
- SystemMessagePromptTemplate,
- AIMessagePromptTemplate,
- HumanMessagePromptTemplate,
-)
-
-template="You are a helpful assistant that translates {input_language} to {output_language}."
-system_message_prompt = SystemMessagePromptTemplate.from_template(template)
-human_template="{text}"
-human_message_prompt = HumanMessagePromptTemplate.from_template(human_template)
-```
-
-
-```python
-chat_prompt = ChatPromptTemplate.from_messages([system_message_prompt, human_message_prompt])
-
-# get a chat completion from the formatted messages
-chat(chat_prompt.format_prompt(input_language="English", output_language="French", text="I love programming.").to_messages())
-```
-
-
-
-```
- AIMessage(content="J'adore la programmation.", additional_kwargs={})
-```
-
-
-
-If you wanted to construct the MessagePromptTemplate more directly, you could create a PromptTemplate outside and then pass it in, e.g.:
-
-
-```python
-prompt=PromptTemplate(
- template="You are a helpful assistant that translates {input_language} to {output_language}.",
- input_variables=["input_language", "output_language"],
-)
-system_message_prompt = SystemMessagePromptTemplate(prompt=prompt)
-```

+# Concepts
+
+The core element of any language model application is...the model. LangChain gives you the building blocks to interface with any language model. Everything in this section is about making it easier to work with models. This largely involves a clear interface for what a model is, helper utils for constructing inputs to models, and helper utils for working with the outputs of models.
+
+## Models
+
+There are two main types of models that LangChain integrates with: LLMs and Chat Models. These are defined by their input and output types.
+
+### LLMs
+
+LLMs in LangChain refer to pure text completion models.
+The APIs they wrap take a string prompt as input and output a string completion. OpenAI's GPT-3 is implemented as an LLM.
+
+### Chat Models
+Chat models are often backed by LLMs but tuned specifically for having conversations.
+Crucially, their provider APIs use a different interface than pure text completion models. Instead of a single string,
+they take a list of chat messages as input and they return an AI message as output. See the section below for more details on what exactly a message consists of. GPT-4 and Anthropic's Claude-2 are both implemented as chat models.
+
+### Considerations
+
+These two API types have pretty different input and output schemas. This means that best way to interact with them may be quite different. Although LangChain makes it possible to treat them interchangeably, that doesn't mean you **should**. In particular, the prompting strategies for LLMs vs ChatModels may be quite different. This means that you will want to make sure the prompt you are using is designed for the model type you are working with.
+
+Additionally, not all models are the same. Different models have different prompting strategies that work best for them. For example, Anthropic's models work best with XML while OpenAI's work best with JSON. This means that the prompt you use for one model may not transfer to other ones. LangChain provides a lot of default prompts, however these are not guaranteed to work well with the model are you using. Historically speaking, most prompts work well with OpenAI but are not heavily tested on other models. This is something we are working to address, but it is something you should keep in mind.
+
+
+## Messages
+
+ChatModels 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 are this way)
+- 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 `functional_call` if using OpenAI Function calling.
+
+
+### SystemMessage
+
+This represents a system message. Only some models support this. This tells the model how to behave. This generally only consists of content.
+
+### 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.
+
+## Prompts
+
+The inputs to language models are often called prompts. Oftentimes, the user input from your app is not the direct input to the model. Rather, their input is transformed in some way to produce the string or list of messages that does go into the model. The objects that take user input and transform it into the final string or messages are known as "Prompt Templates". LangChain provides several abstractions to make working with prompts easier.
+
+### PromptValue
+
+ChatModels and LLMs take different input types. PromptValue is a class designed to be interoperable between the two. It exposes a method to be cast to a string (to work with LLMs) and another to be cast to a list of messages (to work with ChatModels).
+
+### PromptTemplate
+
+This is an example of a prompt template. This consists of a template string. This string is then formatted with user inputs to produce a final string.
+
+### MessagePromptTemplate
+
+This is an example of a prompt template. This consists of a template **message** - meaning a specific role and a PromptTemplate. This PromptTemplate is then formatted with user inputs to produce a final string that becomes the `content` of this message.
+
+#### HumanMessagePromptTemplate
+
+This is MessagePromptTemplate that produces a HumanMessage.
+
+#### AIMessagePromptTemplate
+
+This is MessagePromptTemplate that produces an AIMessage.
+
+#### SystemMessagePromptTemplate
+
+This is MessagePromptTemplate that produces a SystemMessage.
+
+### MessagesPlaceholder
+
+Oftentimes inputs to prompts can be a list of messages. This is when you would use a MessagesPlaceholder. These objects are parameterized by a `variable_name` argument. The input with the same value as this `variable_name` value should be a list of messages.
+
+### ChatPromptTemplate
+
+This is an example of a prompt template. This consists of a list of MessagePromptTemplates or MessagePlaceholders. These are then formatted with user inputs to produce a final list of messages.
+
+## Output Parsers
+
+The output of models are either strings or a message. Oftentimes, the string or messages contains information formatted in a specific format to be used downstream (e.g. a comma separated list, or JSON blob). Output parsers are responsible for taking in the output of a model and transforming it into a more usable form. These generally work on the `content` of the output message, but occasionally work on values in the `additional_kwargs` field.
+
+### StrOutputParser
+
+This is a simple output parser that just converts the output of a language model (LLM or ChatModel) into a string. If the model is an LLM (and therefore outputs a string) it just passes that string through. If the output is a ChatModel (and therefore outputs a message) it passes through the `.content` attribute of the message.
+
+### OpenAI Functions Parsers
+
+There are a few parsers dedicated to working with OpenAI function calling. They take the output of the `function_call` and `arguments` parameters (which are inside `additional_kwargs`) and work with those, largely ignoring content.
+
+### Agent Output Parsers
+
+[Agents](../agents) are systems that use language models to determine what steps to take. The output of a language model therefore needs to be parsed into some schema that can represent what actions (if any) are to be taken. AgentOutputParsers are responsible for taking raw LLM or ChatModel output and converting it to that schema. The logic inside these output parsers can differ depending on the model and prompting strategy being used.

+# LLMs
+
+Large Language Models (LLMs) are a core component of LangChain.
+LangChain does not serve its own LLMs, but rather provides a standard interface for interacting with many different LLMs. To be specific, this interface is one that takes as input a string and returns a string.
+
+
+There are lots of LLM providers (OpenAI, Cohere, Hugging Face, etc) - the `LLM` class is designed to provide a standard interface for all of them.
+
+## [Quick Start](./quick_start)
+
+Check out [this quick start](./quick_start) to get an overview of working with LLMs, including all the different methods they expose
+
+## [Integrations](/docs/integrations/llms/)
+
+For a full list of all LLM integrations that LangChain provides, please go to the [Integrations page](/docs/integrations/llms/)
+
+## How-To Guides
+
+We have several how-to guides for more advanced usage of LLMs.
+This includes:
+
+- [How to write a custom LLM class](./custom_llm)
+- [How to cache LLM responses](./llm_caching)
+- [How to stream responses from an LLM](./streaming_llm)
+- [How to track token usage in an LLM call)(./token_usage_tracking)

-
-
-
-## Optional caching in chains
-You can also turn off caching for particular nodes in chains. Note that because of certain interfaces, it's often easier to construct the chain first, and then edit the LLM afterwards.
-
-As an example, we will load a summarizer map-reduce chain. We will cache results for the map-step, but then not freeze it for the combine step.
-
-
-```python
-llm = OpenAI(model_name="gpt-3.5-turbo-instruct")
-no_cache_llm = OpenAI(model_name="gpt-3.5-turbo-instruct", cache=False)
-```
-
-
-```python
-from langchain.text_splitter import CharacterTextSplitter
-from langchain.chains.mapreduce import MapReduceChain
-
-text_splitter = CharacterTextSplitter()
-```
-
-
-```python
-with open('../../../state_of_the_union.txt') as f:
- state_of_the_union = f.read()
-texts = text_splitter.split_text(state_of_the_union)
-```
-
-
-```python
-from langchain.docstore.document import Document
-docs = [Document(page_content=t) for t in texts[:3]]
-from langchain.chains.summarize import load_summarize_chain
-```
-
-
-```python
-chain = load_summarize_chain(llm, chain_type="map_reduce", reduce_llm=no_cache_llm)
-```
-
-
-```python
-chain.run(docs)
-```
-
-
-
-```
- CPU times: user 452 ms, sys: 60.3 ms, total: 512 ms
- Wall time: 5.09 s

- '\n\nPresident Biden is discussing the American Rescue Plan and the Bipartisan Infrastructure Law, which will create jobs and help Americans. He also talks about his vision for America, which includes investing in education and infrastructure. In response to Russian aggression in Ukraine, the United States is joining with European allies to impose sanctions and isolate Russia. American forces are being mobilized to protect NATO countries in the event that Putin decides to keep moving west. The Ukrainians are bravely fighting back, but the next few weeks will be hard for them. Putin will pay a high price for his actions in the long run. Americans should not be alarmed, as the United States is taking action to protect its interests and allies.'
-```
-
-
-
-When we run it again, we see that it runs substantially faster but the final answer is different. This is due to caching at the map steps, but not at the reduce step.

-This output parser can be used when you want to return a list of comma-separated items.
-
-```python
-from langchain.output_parsers import CommaSeparatedListOutputParser
-from langchain.prompts import PromptTemplate
-from langchain.llms import OpenAI
-
-output_parser = CommaSeparatedListOutputParser()
-
-format_instructions = output_parser.get_format_instructions()
-prompt = PromptTemplate(
- template="List five {subject}.\n{format_instructions}",
- input_variables=["subject"],
- partial_variables={"format_instructions": format_instructions}
-)
-
-model = OpenAI(temperature=0)
-
-_input = prompt.format(subject="ice cream flavors")
-output = model(_input)
-
-output_parser.parse(output)
-```
-
-The resulting output will be:
-
-

-```
- ['Vanilla',

+Output parsers are responsible for taking the output of an LLM and transforming it to a more suitable format. This is very useful when you are asing LLMs to generate any form of structured data.
+
+Besides having a large collection of different types of output parsers, one distinguishing benefit of LangChain OutputParsers is that many of them support streaming.
+
+## [Quick Start](./quick_start)
+
+See [this quick-start guide](./quick_start) for an introduction to output parsers and how to work with them.
+
+## [Output Parser Types](./types)
+
+LangChain has lots of different types of output parsers. See [this table](./types) for a breakdown of what types exist and when to use them.

-# Auto-fixing parser
-
-This output parser wraps another output parser, and in the event that the first one fails it calls out to another LLM to fix any errors.
-
-But we can do other things besides throw errors. Specifically, we can pass the misformatted output, along with the formatted instructions, to the model and ask it to fix it.
-
-For this example, we'll use the above Pydantic output parser. Here's what happens if we pass it a result that does not comply with the schema:
-
-```python
-from langchain.chat_models import ChatOpenAI
-from langchain.output_parsers import PydanticOutputParser
-from langchain_core.pydantic_v1 import BaseModel, Field
-from typing import List
-```
-
-
-```python
-class Actor(BaseModel):
- name: str = Field(description="name of an actor")
- film_names: List[str] = Field(description="list of names of films they starred in")
-
-actor_query = "Generate the filmography for a random actor."
-
-parser = PydanticOutputParser(pydantic_object=Actor)
-```
-
-
-```python
-misformatted = "{'name': 'Tom Hanks', 'film_names': ['Forrest Gump']}"
-```
-
-
-```python
-parser.parse(misformatted)
-```

-# Structured output parser
-
-This output parser can be used when you want to return multiple fields. While the Pydantic/JSON parser is more powerful, we initially experimented with data structures having text fields only.
-
-```python
-from langchain.output_parsers import StructuredOutputParser, ResponseSchema
-from langchain.prompts import PromptTemplate, ChatPromptTemplate, HumanMessagePromptTemplate
-from langchain.llms import OpenAI
-from langchain.chat_models import ChatOpenAI
-```
-
-Here we define the response schema we want to receive.
-
-
-```python
-response_schemas = [
- ResponseSchema(name="answer", description="answer to the user's question"),
- ResponseSchema(name="source", description="source used to answer the user's question, should be a website.")
-]
-output_parser = StructuredOutputParser.from_response_schemas(response_schemas)
-```
-
-We now get a string that contains instructions for how the response should be formatted, and we then insert that into our prompt.
-
-
-```python
-format_instructions = output_parser.get_format_instructions()
-prompt = PromptTemplate(
- template="answer the users question as best as possible.\n{format_instructions}\n{question}",
- input_variables=["question"],
- partial_variables={"format_instructions": format_instructions}
-)
-```
-
-We can now use this to format a prompt to send to the language model, and then parse the returned result.
-
-
-```python
-model = OpenAI(temperature=0)
-```
-
-
-```python
-_input = prompt.format_prompt(question="what's the capital of france?")
-output = model(_input.to_string())
-```
-
-
-```python
-output_parser.parse(output)
-```
-
-
-
-```
- {'answer': 'Paris',
- 'source': 'https://www.worldatlas.com/articles/what-is-the-capital-of-france.html'}
-```
-
-
-
-And here's an example of using this in a chat model
-
-
-```python
-chat_model = ChatOpenAI(temperature=0)
-```
-
-
-```python
-prompt = ChatPromptTemplate(
- messages=[
- HumanMessagePromptTemplate.from_template("answer the users question as best as possible.\n{format_instructions}\n{question}")
- ],
- input_variables=["question"],
- partial_variables={"format_instructions": format_instructions}
-)
-```
-
-
-```python
-_input = prompt.format_prompt(question="what's the capital of france?")
-output = chat_model(_input.to_messages())
-```
-
-
-```python
-output_parser.parse(output.content)
-```
-
-
-
-```
- {'answer': 'Paris', 'source': 'https://en.wikipedia.org/wiki/Paris'}
-```

+# Output Parser Types
+
+This is a list of output parsers LangChain supports. The table below has various pieces of information:
+
+**Name**: The name of the output parser
+
+**Supports Streaming**: Whether the output parser supports streaming.
+
+**Has Format Instructions**: Whether the output parser has format instructions. This is generally available except when (a) the desired schema is not specified in the prompt but rather in other parameters (like OpenAI function calling), or (b) when the OutputParser wraps another OutputParser.
+
+**Calls LLM**: Whether this output parser itself calls an LLM. This is usually only done by output parsers that attempt to correct misformatted output.
+
+**Input Type**: Expected input type. Most output parsers work on both strings and messages, but some (like OpenAI Functions) need a message with specific kwargs.
+
+**Output Type**: The output type of the object returned by the parser.
+
+**Description**: Our commentary on this output parser and when to use it.
+
+| Name | Supports Streaming | Has Format Instructions | Calls LLM | Input Type | Output Type | Description | | |
+|-----------------|--------------------|-------------------------------|-----------|----------------------------------|----------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---|---|
+| [OpenAIFunctions](./openai_functions) | ✅ | (Passes `functions` to model) | | `Message` (with `function_call`) | JSON object | Uses OpenAI function calling to structure the return output. If you are using a model that supports function calling, this is generally the most reliable method. | | |
+| [JSON](./json) | ✅ | ✅ | | `str \| Message` | JSON object | Returns a JSON object as specified. You can specify a Pydantic model and it will return JSON for that model. Probably the most reliable output parser for getting structured data that does NOT use function calling. | | |
+| [XML](./xml) | ✅ | ✅ | | `str \| Message` | `dict` | Returns a dictionary of tags. Use when XML output is needed. Use with models that are good at writing XML (like Anthropic's). | | |
+| [CSV](./csv) | ✅ | ✅ | | `str \| Message` | `List[str]` | Returns a list of comma separated values. | | |
+| [OutputFixing](./output_fixing) | | | ✅ | `str \| Message` | | Wraps another output parser. If that output parser errors, then this will pass the error message and the bad output to an LLM and ask it to fix the output. | | |
+| [RetryWithError](./retry) | | | ✅ | `str \| Message` | | Wraps another output parser. If that output parser errors, then this will pass the original inputs, the bad output, and the error message to an LLM and ask it to fix it. Compared to OutputFixingParser, this one also sends the original instructions. | | |
+| [Pydantic](./pydantic) | | ✅ | | `str \| Message` | `pydantic.BaseModel` | Takes a user defined Pydantic model and returns data in that format. | | |
+| [YAML](./yaml) | | ✅ | | `str \| Message` | `pydantic.BaseModel` | Takes a user defined Pydantic model and returns data in that format. Uses YAML to encode it. | | |
+| [PandasDataFrame](./pandas_dataframe) | | ✅ | | `str \| Message` | `dict` | Useful for doing operations with pandas DataFrames. | | |
+| [Enum](./enum) | | ✅ | | `str \| Message` | `Enum` | Parses response into one of the provided enum values. | | |
+| [Datetime](./datetime) | | ✅ | | `str \| Message` | `datetime.datetime` | Parses response into a datetime string. | | |
+| [Structured](./structured) | | ✅ | | `str \| Message` | `Dict[str, str]` | An output parser that returns structured information. It is less powerful than other output parsers since it only allows for fields to be strings. This can be useful when you are working with smaller LLMs. | | |

-# Custom example selector
-
-In this tutorial, we'll create a custom example selector that selects examples randomly from a given list of examples.
-
-An `ExampleSelector` must implement two methods:
-
-1. An `add_example` method which takes in an example and adds it into the ExampleSelector
-2. A `select_examples` method which takes in input variables (which are meant to be user input) and returns a list of examples to use in the few-shot prompt.
-
-Let's implement a custom `ExampleSelector` that just selects two examples at random.
-
-**Note:**
-Take a look at the current set of example selector implementations supported in LangChain [here](/docs/modules/model_io/prompts/example_selectors/).
-
-
-
-## Implement custom example selector
-
-```python
-from langchain.prompts.example_selector.base import BaseExampleSelector
-from typing import Dict, List
-import numpy as np
-
-
-class CustomExampleSelector(BaseExampleSelector):
-
- def __init__(self, examples: List[Dict[str, str]]):
- self.examples = examples
-
- def add_example(self, example: Dict[str, str]) -> None:
- """Add new example to store for a key."""
- self.examples.append(example)
-
- def select_examples(self, input_variables: Dict[str, str]) -> List[dict]:
- """Select which examples to use based on the inputs."""
- return np.random.choice(self.examples, size=2, replace=False)
-
-```
-
-
-## Use custom example selector
-
-```python
-
-examples = [
- {"foo": "1"},
- {"foo": "2"},
- {"foo": "3"}
-]
-
-# Initialize example selector.
-example_selector = CustomExampleSelector(examples)
-
-# Select examples
-example_selector.select_examples({"foo": "foo"})
-# -> array([{'foo': '2'}, {'foo': '3'}], dtype=object)
-
-# Add new example to the set of examples
-example_selector.add_example({"foo": "4"})
-example_selector.examples
-# -> [{'foo': '1'}, {'foo': '2'}, {'foo': '3'}, {'foo': '4'}]
-
-# Select examples
-example_selector.select_examples({"foo": "foo"})
-# -> array([{'foo': '1'}, {'foo': '4'}], dtype=object)

-# Example selectors
-
-If you have a large number of examples, you may need to select which ones to include in the prompt. The Example Selector is the class responsible for doing so.
-
-The base interface is defined as below:
-
-```python
-class BaseExampleSelector(ABC):
- """Interface for selecting examples to include in prompts."""
-
- @abstractmethod
- def select_examples(self, input_variables: Dict[str, str]) -> List[dict]:
- """Select which examples to use based on the inputs."""
-```
-
-The only method it needs to define is a ``select_examples`` method. This takes in the input variables and then returns a list of examples. It is up to each specific implementation as to how those examples are selected.

-LangChain provides several classes and functions to help construct and work with prompts.
+## [Quick Start](./quick_start)
-- [Prompt templates](/docs/modules/model_io/prompts/prompt_templates/): Parametrized model inputs
-- [Example selectors](/docs/modules/model_io/prompts/example_selectors/): Dynamically select examples to include in prompts
\ No newline at end of file
+This [quick start](./quick_start) provides a basic overview of how to work with prompts.
+
+## How-To Guides
+
+We have many how-to guides for working with prompts. These include:
+
+- [How to use few-shot examples with LLMs](./few_shot_examples)
+- [How to use few-shot examples with chat models](./few_shot_examples_chat)
+- [How to use example selectors](./example_selectors)
+- [How to partial prompts](./partial)
+- [How to work with message prompts](./message_prompts)
+- [How to compose prompts together](./composition)
+- [How to create a pipeline prompt](./pipeline)
+
+## [Example Selector Types](./example_selector_types)
+
+LangChain has a few different types of example selectors you can use off the shelf. You can explore those types [here](./example_selector_types)

If you get the `foo` value early on in the chain, but the `baz` value later, it can be annoying to wait until you have both variables in the same place to pass them to the prompt template.

- "# Connecting to a Feature Store\n",
- "\n",
- "Feature stores are a concept from traditional machine learning that make sure data fed into models is up-to-date and relevant. For more on this, see [here](https://www.tecton.ai/blog/what-is-a-feature-store/).\n",
- "\n",
- "This concept is extremely relevant when considering putting LLM applications in production. In order to personalize LLM applications, you may want to combine LLMs with up-to-date information about particular users. Feature stores can be a great way to keep that data fresh, and LangChain provides an easy way to combine that data with LLMs.\n",
- "\n",
- "In this notebook we will show how to connect prompt templates to feature stores. The basic idea is to call a feature store from inside a prompt template to retrieve values that are then formatted into the prompt."

-# Few-shot prompt templates
-
-In this tutorial, we'll learn how to create a prompt template that uses few-shot examples. A few-shot prompt template can be constructed from either a set of examples, or from an Example Selector object.
-
-### Use Case
-
-In this tutorial, we'll configure few-shot examples for self-ask with search.
-
-
-## Using an example set
-
-### Create the example set
-
-To get started, create a list of few-shot examples. Each example should be a dictionary with the keys being the input variables and the values being the values for those input variables.
-
-```python
-from langchain.prompts.few_shot import FewShotPromptTemplate
-from langchain.prompts.prompt import PromptTemplate
-
-examples = [
- {
- "question": "Who lived longer, Muhammad Ali or Alan Turing?",
- "answer":
-"""
-Are follow up questions needed here: Yes.
-Follow up: How old was Muhammad Ali when he died?
-Intermediate answer: Muhammad Ali was 74 years old when he died.
-Follow up: How old was Alan Turing when he died?
-Intermediate answer: Alan Turing was 41 years old when he died.
-So the final answer is: Muhammad Ali
-"""
- },
- {
- "question": "When was the founder of craigslist born?",
- "answer":
-"""
-Are follow up questions needed here: Yes.
-Follow up: Who was the founder of craigslist?
-Intermediate answer: Craigslist was founded by Craig Newmark.
-Follow up: When was Craig Newmark born?
-Intermediate answer: Craig Newmark was born on December 6, 1952.
-So the final answer is: December 6, 1952
-"""
- },
- {
- "question": "Who was the maternal grandfather of George Washington?",
- "answer":
-"""
-Are follow up questions needed here: Yes.
-Follow up: Who was the mother of George Washington?
-Intermediate answer: The mother of George Washington was Mary Ball Washington.
-Follow up: Who was the father of Mary Ball Washington?
-Intermediate answer: The father of Mary Ball Washington was Joseph Ball.
-So the final answer is: Joseph Ball
-"""
- },
- {
- "question": "Are both the directors of Jaws and Casino Royale from the same country?",
- "answer":
-"""
-Are follow up questions needed here: Yes.
-Follow up: Who is the director of Jaws?
-Intermediate Answer: The director of Jaws is Steven Spielberg.
-Follow up: Where is Steven Spielberg from?
-Intermediate Answer: The United States.
-Follow up: Who is the director of Casino Royale?
-Intermediate Answer: The director of Casino Royale is Martin Campbell.
-Follow up: Where is Martin Campbell from?
-Intermediate Answer: New Zealand.
-So the final answer is: No
-"""
- }
-]
-```
-
-### Create a formatter for the few-shot examples
-
-Configure a formatter that will format the few-shot examples into a string. This formatter should be a `PromptTemplate` object.
-
-
-```python
-example_prompt = PromptTemplate(input_variables=["question", "answer"], template="Question: {question}\n{answer}")
-
-print(example_prompt.format(**examples[0]))
-```
-
-
-
-```
- Question: Who lived longer, Muhammad Ali or Alan Turing?
-
- Are follow up questions needed here: Yes.
- Follow up: How old was Muhammad Ali when he died?
- Intermediate answer: Muhammad Ali was 74 years old when he died.
- Follow up: How old was Alan Turing when he died?
- Intermediate answer: Alan Turing was 41 years old when he died.
- So the final answer is: Muhammad Ali
-
-```
-
-
-
-### Feed examples and formatter to `FewShotPromptTemplate`
-
-Finally, create a `FewShotPromptTemplate` object. This object takes in the few-shot examples and the formatter for the few-shot examples.
-
-
-```python
-prompt = FewShotPromptTemplate(
- examples=examples,
- example_prompt=example_prompt,
- suffix="Question: {input}",
- input_variables=["input"]
-)
-
-print(prompt.format(input="Who was the father of Mary Ball Washington?"))
-```
-
-
-
-```
- Question: Who lived longer, Muhammad Ali or Alan Turing?
-
- Are follow up questions needed here: Yes.
- Follow up: How old was Muhammad Ali when he died?
- Intermediate answer: Muhammad Ali was 74 years old when he died.
- Follow up: How old was Alan Turing when he died?
- Intermediate answer: Alan Turing was 41 years old when he died.

-
- Are follow up questions needed here: Yes.
- Follow up: Who was the founder of craigslist?
- Intermediate answer: Craigslist was founded by Craig Newmark.
- Follow up: When was Craig Newmark born?
- Intermediate answer: Craig Newmark was born on December 6, 1952.
- So the final answer is: December 6, 1952
-
-
- Question: Who was the maternal grandfather of George Washington?
-
- Are follow up questions needed here: Yes.
- Follow up: Who was the mother of George Washington?
- Intermediate answer: The mother of George Washington was Mary Ball Washington.
- Follow up: Who was the father of Mary Ball Washington?
- Intermediate answer: The father of Mary Ball Washington was Joseph Ball.
- So the final answer is: Joseph Ball
-
-
- Question: Are both the directors of Jaws and Casino Royale from the same country?
-
- Are follow up questions needed here: Yes.
- Follow up: Who is the director of Jaws?
- Intermediate Answer: The director of Jaws is Steven Spielberg.
- Follow up: Where is Steven Spielberg from?
- Intermediate Answer: The United States.
- Follow up: Who is the director of Casino Royale?
- Intermediate Answer: The director of Casino Royale is Martin Campbell.
- Follow up: Where is Martin Campbell from?

-
-
- Question: Who was the father of Mary Ball Washington?

-
-## Using an example selector
-
-### Feed examples into `ExampleSelector`
-
-We will reuse the example set and the formatter from the previous section. However, instead of feeding the examples directly into the `FewShotPromptTemplate` object, we will feed them into an `ExampleSelector` object.
-
-
-In this tutorial, we will use the `SemanticSimilarityExampleSelector` class. This class selects few-shot examples based on their similarity to the input. It uses an embedding model to compute the similarity between the input and the few-shot examples, as well as a vector store to perform the nearest neighbor search.
-
-
-```python
-from langchain.prompts.example_selector import SemanticSimilarityExampleSelector
-from langchain.vectorstores import Chroma
-from langchain.embeddings import OpenAIEmbeddings
-
-
-example_selector = SemanticSimilarityExampleSelector.from_examples(
- # This is the list of examples available to select from.
- examples,
- # This is the embedding class used to produce embeddings which are used to measure semantic similarity.
- OpenAIEmbeddings(),
- # This is the VectorStore class that is used to store the embeddings and do a similarity search over.
- Chroma,
- # This is the number of examples to produce.
- k=1
-)
-
-# Select the most similar example to the input.
-question = "Who was the father of Mary Ball Washington?"
-selected_examples = example_selector.select_examples({"question": question})
-print(f"Examples most similar to the input: {question}")
-for example in selected_examples:
- print("\n")
- for k, v in example.items():
- print(f"{k}: {v}")
-```
-
-
-
-```
- Running Chroma using direct local API.
- Using DuckDB in-memory for database. Data will be transient.
- Examples most similar to the input: Who was the father of Mary Ball Washington?
-
-
- question: Who was the maternal grandfather of George Washington?
- answer:
- Are follow up questions needed here: Yes.
- Follow up: Who was the mother of George Washington?
- Intermediate answer: The mother of George Washington was Mary Ball Washington.
- Follow up: Who was the father of Mary Ball Washington?
- Intermediate answer: The father of Mary Ball Washington was Joseph Ball.
- So the final answer is: Joseph Ball
-
-```
-
-
-
-### Feed example selector into `FewShotPromptTemplate`
-
-Finally, create a `FewShotPromptTemplate` object. This object takes in the example selector and the formatter for the few-shot examples.
-
-
-```python
-prompt = FewShotPromptTemplate(
- example_selector=example_selector,
- example_prompt=example_prompt,

- input_variables=["input"]
-)
-
-print(prompt.format(input="Who was the father of Mary Ball Washington?"))
-```
-
-
-
-```
- Question: Who was the maternal grandfather of George Washington?
-
- Are follow up questions needed here: Yes.
- Follow up: Who was the mother of George Washington?

-# Template formats
-
-`PromptTemplate` by default uses Python f-string as its template format. However, it can also use other formats like `jinja2`, specified through the `template_format` argument.
-
-To use the `jinja2` template:
-
-```python
-from langchain.prompts import PromptTemplate
-
-jinja2_template = "Tell me a {{ adjective }} joke about {{ content }}"
-prompt = PromptTemplate.from_template(jinja2_template, template_format="jinja2")
-
-prompt.format(adjective="funny", content="chickens")
-# Output: Tell me a funny joke about chickens.
-```
-
-To use the Python f-string template:
-
-```python
-from langchain.prompts import PromptTemplate
-
-fstring_template = """Tell me a {adjective} joke about {content}"""
-prompt = PromptTemplate.from_template(fstring_template)
-
-prompt.format(adjective="funny", content="chickens")
-# Output: Tell me a funny joke about chickens.
-```
-
-Currently, only `jinja2` and `f-string` are supported. For other formats, kindly raise an issue on the [Github page](https://github.com/langchain-ai/langchain/issues).

-# Types of `MessagePromptTemplate`
-
-LangChain provides different types of `MessagePromptTemplate`. The most commonly used are `AIMessagePromptTemplate`, `SystemMessagePromptTemplate` and `HumanMessagePromptTemplate`, which create an AI message, system message and human message respectively.
-
-However, in cases where the chat model supports taking chat message with arbitrary role, you can use `ChatMessagePromptTemplate`, which allows user to specify the role name.
-
-
-```python
-from langchain.prompts import ChatMessagePromptTemplate
-
-prompt = "May the {subject} be with you"

-LangChain also provides `MessagesPlaceholder`, which gives you full control of what messages to be rendered during formatting.

-# Partial prompt templates
-
-Like other methods, it can make sense to "partial" a prompt template - e.g. pass in a subset of the required values, as to create a new prompt template which expects only the remaining subset of values.
-
-LangChain supports this in two ways:
-1. Partial formatting with string values.
-2. Partial formatting with functions that return string values.
-
-These two different ways support different use cases. In the examples below, we go over the motivations for both use cases as well as how to do it in LangChain.
-
-## Partial with strings
-
-One common use case for wanting to partial a prompt template is if you get some of the variables before others. For example, suppose you have a prompt template that requires two variables, `foo` and `baz`. If you get the `foo` value early on in the chain, but the `baz` value later, it can be annoying to wait until you have both variables in the same place to pass them to the prompt template. Instead, you can partial the prompt template with the `foo` value, and then pass the partialed prompt template along and just use that. Below is an example of doing this:
-
-
-
-
-```python
-from langchain.prompts import PromptTemplate
-```
-
-
-```python
-prompt = PromptTemplate(template="{foo}{bar}", input_variables=["foo", "bar"])
-partial_prompt = prompt.partial(foo="foo");
-print(partial_prompt.format(bar="baz"))
-```
-
-
-
-```
- foobaz
-```
-
-
-
-You can also just initialize the prompt with the partialed variables.
-
-
-```python
-prompt = PromptTemplate(template="{foo}{bar}", input_variables=["bar"], partial_variables={"foo": "foo"})
-print(prompt.format(bar="baz"))
-```
-
-
-
-```
- foobaz
-```
-
-
-
-## Partial with functions
-
-The other common use is to partial with a function. The use case for this is when you have a variable you know that you always want to fetch in a common way. A prime example of this is with date or time. Imagine you have a prompt which you always want to have the current date. You can't hard code it in the prompt, and passing it along with the other input variables is a bit annoying. In this case, it's very handy to be able to partial the prompt with a function that always returns the current date.
-
-
-```python
-from datetime import datetime
-
-def _get_datetime():
- now = datetime.now()
- return now.strftime("%m/%d/%Y, %H:%M:%S")
-```
-
-
-```python
-prompt = PromptTemplate(
- template="Tell me a {adjective} joke about the day {date}",
- input_variables=["adjective", "date"]
-);
-partial_prompt = prompt.partial(date=_get_datetime)
-print(partial_prompt.format(adjective="funny"))
-```
-
-
-
-```
- Tell me a funny joke about the day 02/27/2023, 22:15:16
-```
-
-
-
-You can also just initialize the prompt with the partialed variables, which often makes more sense in this workflow.
-
-
-```python
-prompt = PromptTemplate(
- template="Tell me a {adjective} joke about the day {date}",
- input_variables=["adjective"],
- partial_variables={"date": _get_datetime}
-);
-print(prompt.format(adjective="funny"))
-```
-
-
-
-```
- Tell me a funny joke about the day 02/27/2023, 22:15:16
-```

-# Composition
-
-This notebook goes over how to compose multiple prompts together. This can be useful when you want to reuse parts of prompts. This can be done with a PipelinePrompt. A PipelinePrompt consists of two main parts:
-
-- Final prompt: The final prompt that is returned
-- Pipeline prompts: A list of tuples, consisting of a string name and a prompt template. Each prompt template will be formatted and then passed to future prompt templates as a variable with the same name.
-
-```python
-from langchain.prompts.pipeline import PipelinePromptTemplate
-from langchain.prompts.prompt import PromptTemplate
-```
-
-
-```python
-full_template = """{introduction}
-
-{example}
-
-{start}"""
-full_prompt = PromptTemplate.from_template(full_template)
-```
-
-
-```python
-introduction_template = """You are impersonating {person}."""
-introduction_prompt = PromptTemplate.from_template(introduction_template)
-```
-
-
-```python
-example_template = """Here's an example of an interaction:
-
-Q: {example_q}
-A: {example_a}"""
-example_prompt = PromptTemplate.from_template(example_template)
-```
-
-
-```python
-start_template = """Now, do this for real!
-
-Q: {input}
-A:"""
-start_prompt = PromptTemplate.from_template(start_template)
-```
-
-
-```python
-input_prompts = [
- ("introduction", introduction_prompt),
- ("example", example_prompt),
- ("start", start_prompt)
-]
-pipeline_prompt = PipelinePromptTemplate(final_prompt=full_prompt, pipeline_prompts=input_prompts)
-```
-
-
-```python
-pipeline_prompt.input_variables
-```
-
-
-
-```
- ['example_a', 'person', 'example_q', 'input']
-```
-
-
-
-
-```python
-print(pipeline_prompt.format(
- person="Elon Musk",
- example_q="What's your favorite car?",
- example_a="Tesla",
- input="What's your favorite social media site?"
-))
-```
-
-
-
-```
- You are impersonating Elon Musk.
- Here's an example of an interaction:
-
- Q: What's your favorite car?
- A: Tesla
- Now, do this for real!
-
- Q: What's your favorite social media site?
- A:

-# Validate template
-
-By default, `PromptTemplate` will validate the `template` string by checking whether the `input_variables` match the variables defined in `template`. You can disable this behavior by setting `validate_template` to `False`.
-
-```python
-template = "I am learning langchain because {reason}."
-
-prompt_template = PromptTemplate(template=template,
- input_variables=["reason", "foo"]) # ValueError due to extra variables
-prompt_template = PromptTemplate(template=template,
- input_variables=["reason", "foo"],
- validate_template=False) # No error

+# Quickstart
+
+The quick start will cover the basics of working with language models. It will introduce the two different types of models - LLMs and ChatModels. It will then cover how to use PromptTemplates to format the inputs to these models, and how to use Output Parsers to work with the outputs. For a deeper conceptual guide into these topics - please see [this documentation](./concepts)
+
+## Models
+For this getting started guide, we will provide two options: using OpenAI (a popular model available via API) or using a local open source model.
+
+import Tabs from '@theme/Tabs';
+import TabItem from '@theme/TabItem';
+import CodeBlock from "@theme/CodeBlock";
+
+
+
+
+First we'll need to install their Python package:
+
+```shell
+pip install 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.chat_models import ChatOpenAI
+from langchain.llms import OpenAI
+
+llm = OpenAI()
+chat_model = ChatOpenAI()
+```
+
+If you'd prefer not to set an environment variable you can pass the key in directly via the `openai_api_key` named parameter when initiating the OpenAI LLM class:
+
+```python
+from langchain.chat_models import ChatOpenAI
+llm = ChatOpenAI(openai_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.llms import Ollama
+from langchain.chat_models import ChatOllama
+
+llm = Ollama(model="llama2")
+chat_model = ChatOllama()
+```
+
+
+
+
+Both `llm` and `chat_model` are objects that represent configuration for a particular model.
+You can initialize them with parameters like `temperature` and others, and pass them around.
+The main difference between them is their input and output schemas.
+The LLM objects take string as input and output string.
+The ChatModel objects take a list of messages as input and output a message.
+For a deeper conceptual explanation of this difference please see [this documentation](./concepts)
+
+We can see the difference between an LLM and a ChatModel when we invoke it.
+
+```python
+from langchain.schema import HumanMessage
+
+text = "What would be a good company name for a company that makes colorful socks?"
+messages = [HumanMessage(content=text)]
+
+llm.invoke(text)
+# >> Feetful of Fun
+
+chat_model.invoke(messages)
+# >> AIMessage(content="Socks O'Color")
+```
+
+The LLM returns a string, while the ChatModel returns a message.
+
+## Prompt Templates
+
+Most LLM applications do not pass user input directly into an LLM. Usually they will add the user input to a larger piece of text, called a prompt template, that provides additional context on the specific task at hand.
+
+In the previous example, the text we passed to the model contained instructions to generate a company name. For our application, it would be great if the user only had to provide the description of a company/product without worrying about giving the model instructions.
+
+PromptTemplates help with exactly this!
+They bundle up all the logic for going from user input into a fully formatted prompt.
+This can start off very simple - for example, a prompt to produce the above string would just be:
+
+```python
+from langchain.prompts import PromptTemplate
+
+prompt = PromptTemplate.from_template("What is a good name for a company that makes {product}?")
+prompt.format(product="colorful socks")
+```
+
+```python
+What is a good name for a company that makes colorful socks?
+```
+
+However, the advantages of using these over raw string formatting are several.
+You can "partial" out variables - e.g. you can format only some of the variables at a time.
+You can compose them together, easily combining different templates into a single prompt.
+For explanations of these functionalities, see the [section on prompts](/docs/modules/model_io/prompts) for more detail.
+
+`PromptTemplate`s can also be used to produce a list of messages.
+In this case, the prompt not only contains information about the content, but also each message (its role, its position in the list, etc.).
+Here, what happens most often is a `ChatPromptTemplate` is a list of `ChatMessageTemplates`.
+Each `ChatMessageTemplate` contains instructions for how to format that `ChatMessage` - its role, and then also its content.
+Let's take a look at this below:
+
+```python
+from langchain.prompts.chat import ChatPromptTemplate
+
+template = "You are a helpful assistant that translates {input_language} to {output_language}."
+human_template = "{text}"
+
+chat_prompt = ChatPromptTemplate.from_messages([
+ ("system", template),
+ ("human", human_template),
+])
+
+chat_prompt.format_messages(input_language="English", output_language="French", text="I love programming.")
+```
+
+```pycon
+[
+ SystemMessage(content="You are a helpful assistant that translates English to French.", additional_kwargs={}),
+ HumanMessage(content="I love programming.")
+]
+```
+
+
+ChatPromptTemplates can also be constructed in other ways - see the [section on prompts](/docs/modules/model_io/prompts) for more detail.
+
+## Output parsers
+
+`OutputParser`s convert the raw output of a language model into a format that can be used downstream.
+There are a few main types of `OutputParser`s, including:
+
+- Convert text from `LLM` into structured information (e.g. JSON)
+- Convert a `ChatMessage` into just a string
+- Convert the extra information returned from a call besides the message (like OpenAI function invocation) into a string.
+
+For full information on this, see the [section on output parsers](/docs/modules/model_io/output_parsers).
+
+In this getting started guide, we use a simple one that parses a list of comma separated values.
+
+```python
+from langchain.output_parsers import CommaSeparatedListOutputParser
+
+output_parser = CommaSeparatedListOutputParser()
+output_parser.parse("hi, bye")
+# >> ['hi', 'bye']
+```
+
+## Composing with LCEL
+
+We can now combine all these into one chain.
+This chain will take input variables, pass those to a prompt template to create a prompt, pass the prompt to a language model, and then pass the output through an (optional) output parser.
+This is a convenient way to bundle up a modular piece of logic.
+Let's see it in action!
+
+```python
+template = "Generate a list of 5 {text}.\n\n{format_instructions}"
+
+chat_prompt = ChatPromptTemplate.from_template(template)
+chat_prompt = chat_prompt.partial(format_instructions=output_parser.get_format_instructions())
+chain = chat_prompt | chat_model | output_parser
+chain.invoke({"text": "colors"})
+# >> ['red', 'blue', 'green', 'yellow', 'orange']
+```
+
+Note that we are using the `|` syntax to join these components together.
+This `|` syntax is powered by the LangChain Expression Language (LCEL) and relies on the universal `Runnable` interface that all of these objects implement.
+To learn more about LCEL, read the documentation [here](/docs/expression_language).
+

It utilizes more test-time computation and sheds light on the model\\'s thinking process.\\n\\n2. Prompting with LLM: Language Model (LLM) can be used to prompt the model with simple instructions like \"Steps for XYZ\" or \"What are the subgoals for achieving XYZ?\" This allows the model to generate a sequence of subtasks or thought steps.\\n\\n3. Task-specific instructions: For certain tasks, task-specific instructions can be provided to guide the model in decomposing the task. For example, for writing a novel, the instruction \"Write a story outline\" can be given to break down the task into manageable steps.\\n\\n4.

+# python-lint
+
+This agent specializes in generating high-quality Python code with a focus on proper formatting and linting. It uses `black`, `ruff`, and `mypy` to ensure the code meets standard quality checks.
+
+This streamlines the coding process by integrating and responding to these checks, resulting in reliable and consistent code output.
+
+It cannot actually execute the code it writes, as code execution may introduce additional dependencies and potential security vulnerabilities.
+This makes the agent both a secure and efficient solution for code generation tasks.
+
+You can use it to generate Python code directly, or network it with planning and execution agents.
+
+## Environment Setup
+
+- Install `black`, `ruff`, and `mypy`: `pip install -U black ruff mypy`
+- Set `OPENAI_API_KEY` environment variable.
+
+## Usage
+
+To use this package, you should first have the LangChain CLI installed:
+
+```shell
+pip install -U langchain-cli
+```
+
+To create a new LangChain project and install this as the only package, you can do:
+
+```shell
+langchain app new my-app --package python-lint
+```
+
+If you want to add this to an existing project, you can just run:
+
+```shell
+langchain app add python-lint
+```
+
+And add the following code to your `server.py` file:
+```python
+from python_lint import agent_executor as python_lint_agent
+
+add_routes(app, python_lint_agent, path="/python-lint")
+```
+
+(Optional) Let's now configure LangSmith.
+LangSmith will help us trace, monitor and debug LangChain applications.
+LangSmith is currently in private beta, you can sign up [here](https://smith.langchain.com/).
+If you don't have access, you can skip this section
+
+
+```shell
+export LANGCHAIN_TRACING_V2=true
+export LANGCHAIN_API_KEY=
+export LANGCHAIN_PROJECT= # if not specified, defaults to "default"
+```
+
+If you are inside this directory, then you can spin up a LangServe instance directly by:
+
+```shell
+langchain serve
+```
+
+This will start the FastAPI app with a server is running locally at
+[http://localhost:8000](http://localhost:8000)
+
+We can see all templates at [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)
+We can access the playground at [http://127.0.0.1:8000/python-lint/playground](http://127.0.0.1:8000/python-lint/playground)
+
+We can access the template from code with:
+
+```python
+from langserve.client import RemoteRunnable
+
+runnable = RemoteRunnable("http://localhost:8000/python-lint")
+```
