Samantha Interface Assistant: Experimental Environment Designed to Democratize the Use of Open Source Large Language Models (LLM)
💻 Samantha is just a simple interface assistant for open source text generation artificial intelligence models, developed under Open Science principles (open methodology, open source, open data, open access, open peer review and open educational resources) and MIT License for use on common Windows computers (without GPU). The program runs the LLM locally, free of charge and unlimitedly, without the need for an internet connection, except to download GGUF models or when required by the execution of the code created by the models (g.e. to download datasets for data analysis). Its objective is to democratize knowledge about the use of AI and demonstrate that, using the appropriate technique, even small models are capable of producing responses similar to those of larger ones. Her mission is to help explore the boundaries of (realy) open AI models.
What is Open Source AI (opensource.org)
Artificial Intelligence Papers (arxiv.org)
🕵️♀️ Samantha is being developed to assist in the exercise of social and institutional control of public administration, considering the worrying current scenario of increasing loss of citizens' trust in control institutions. Its features allow it to be used by anyone interested in exploring open source artificial intelligence models, especially Python programmers and data scientists. The project originated from the MPC-ES team's need to develop a system that would allow understanding the process of generating tokens by LLM models.
♾️ The system allows the sequential loading of a list of prompts (prompt chaining) and models (model chaining), one model at a time to save memory, as well as the adjustment of their hyperparameters, allowing the response generated by the previous model to be feedbacked and analyzed by the subsequent model to generate the next response (Feedback Loop feature), in an unlimited number of interaction cycles between LLMs without human intervention. Models can interact with the answer provided by the immediately preceding model, so each new response replaces the previous one. You can also use just one model and have it interact with its previous response over an unlimited number of text generation cycles. Use your imagination to combine models, prompts and features!
This video shows an example of interaction between models without human intervention, by chaining models and prompts using Samantha's copy and paste LLM feature. Quantized versions of the Microsoft Phi 3.5 and Google Gemma 2 models (by Bartowski) are challenged to answer a question about human nature created by the Meta Llama 3.1 model (by NousResearch). Responses are also evaluated by the Meta model.

🔗 Some chaining examples without using Samantha's response Feedback Loop feature:
-
(model_1) responds (prompt_1) X number of responses: used to analyze model's deterministic and stochastic behavior with help of the Learning Mode feature, as well as to generate multiple diverse responses with stochastic settings (Video).
-
(model_1) responds (prompt_1, prompt_2, prompt_n): used to execute multiples instructions sequencially with the same model (prompt chaining) (Video).
-
(model_1, model_2, model_n) respond (prompt_1): used to compare models' responses for the same single prompt (model chaining). Useful for comparing different models, as well as quantized versions of the same model.
-
(model_1, model_2, model_n) respond (prompt_1, prompt_2, prompt_n): used to compare models' responses for a list of prompts, as well as to execute a sequence of instructions using disctinct models (model and prompt chaining). Each model respond all prompts. In turn, when using the Single Response per Model feature, each model respond to only one specific prompt.
🔗 Some chaining examples using Samantha's response Feedback Loop feature:
-
(model_1) responds (prompt_1) X number of responses: Used to improve or complement the model's previous response through a fixed user instruction using the same model, as well as to simulate an endless conversation between 2 AIs using a single model (Video).
-
(model_1) responds (prompt_1, prompt_2, prompt_n): used to improve model's previous response through multiples user instructions sequencially with the same model (prompt chaining). Each prompt is used to refine or complete the previous response, as well as to execute a sequence of prompts that depend on the previous response, such as performing Exploratory Data Analysis (EDA) with incremental coding (Video).
-
(model_1, model_2, model_n) respond (prompt_1): Used to improve previous model's response using disctinct models (model chaining), as well as to generate a dialog between different models.
-
(model_1, model_2, model_n) respond (prompt_1, prompt_2, prompt_n): Used to execute a sequence of instructions using disctinct models (model and prompt chaining) and Single response per model feature.
Each of these models and prompts sequences can be executed more than once via the Number of loops feature.
Chain-of-Thought Prompting Elicits Reasoning in Large Language Models (arxiv.org)

But what is a GPT? Visual intro to transformers (3Blue1Brown)
Attention in transformers, visually explained (3Blue1Brown)
🧩 Sequencing of prompts and models allows the generation of long responses by fractioning the user input instruction. Every partial response fits in the model's response length defined in the model training process.
🔧 As an open source tool for automatic self-interaction between AI models, Samantha Interface Assistant was designed to explore reverse prompt engineering with self-improvement feedback loop 🔁. This technique helps small large language models (LLM) to generate more accurate responses by transferring to the model the task of creating the final prompt and corresponding response based on the user's initial imprecise instructions, adding intermediate layers to the prompt construction process. Samantha doesn't have a hidden system prompt like it does with proprietary models. All instructions are controlled by the user. See Anthropic system prompts.
🎲 Thanks to emergent behavior resulting from generalization patterns extracted from training texts, with the right prompt and proper hyperparameter configuration, even small models working together can generate big responses!
The intelligence of the human species is not based on a single intelligent being, but based on a collective intelligence. Individually, we are actually not that intelligent or capable. Our society and economic system is based on having a vast range of institutions made up of diverse individuals with different specializations and expertise. This vast collective intelligence shapes who we are as individuals, and each of us follows our own path in life to become the unique individual, and in turn, contribute back to being part of our ever-expanding collective intelligence as a species. We believe that the development of artificial intelligence will follow a similar, collective path. The future of AI will not consist of a single, gigantic, all-knowing AI system that requires enormous energy to train, run, and maintain, but rather a vast collection of small AI systems–each with their own niche and specialty, interacting with each other, with newer AI systems developed to fill a particular niche. Evolving New Foundation Models: Unleashing the Power of Automating Model Development - Sakana AI
🌎 A Small Step: Samantha is just a movement towards a future where artificial intelligence is not a privilege but a tool for all in a world where individuals can leverage AI to enhance their productivity, creativity, and decision-making without barriers, walking a journey to democratize AI and make it a force for good in our daily lives.
🦾 The Instrumental Nature of AI: Recognizing the technological monopoly of artificial intelligence as a possible instrument of domination and the expansion of social inequalities represents a challenge at this inflection point in history. Noting the flaws of the smaller models during the text generation process aids in this understanding by comparing them with the claimed perfection of the larger proprietary models. It is necessary to reposition things in their proper places and question the romantic reductionist view of attributing human characteristics - such as intelligence (anthropomorphization caused by the psychological phenomenon of pareidolia) - to a technology produced by the human intellect. For this reason, it is essential to demystify artificial intelligence through a didactic approach to how this novel "word/token calculator" works. Certainly, the dopamine of the initial charm artificially created by the market will not withstand the generation of a few hundred tokens (token is the name given to the basic building block of texts that an LLM uses to understand and generate text. A token may be an entire word or part of a word).
✏️ Text Generation Considerations: Users should be aware that the responses generated by AI are derived from the training of its large language models on a vast corpus of text data. The exact sources or processes used by the AI to generate its outputs cannot be precisely cited or identified. The content produced by the AI is not a direct quotation or compilation from specific sources. Instead, it reflects the patterns, statistical relationships, and knowledge that the AI's neural networks have learned and encoded during the training process on the broad data corpus. The responses are generated based on this learned knowledge representation, rather than being retrieved verbatim from any particular source material. While the AI's training data may have included authoritative sources, its outputs are its own synthesized expressions of the learned associations and concepts.
🎯 Objective: The primary objective with Samantha is to inspire 💡 others to create similar - and much better ones, to be sure - systems and to educate users on the utilization of AI. Our goal is to foster a community of developers and enthusiasts who can take the knowledge and tools to further innovate and contribute to the field of open source AI. By doing so, the aim to cultivate a culture of collaboration and sharing, ensuring that the benefits of AI are accessible to all, regardless of their technical background or financial resources. It is believed that by enabling more people to construct and comprehend AI applications, we can collectively drive progress and address societal challenges with informed and diverse perspectives. Let's work together to shape a future where AI is a positive and inclusive force for humanity.
UNESCO's Ethics of Artificial Intelligence Recommendations
OECD programme on AI in Work, Innovation, Productivity and Skills
🚨 The Human Cost of Innovation: While this system aims to empower users and democratize access to AI, it's crucial to acknowledge the ethical implications of this technology. The development of powerful AI systems often relies on the exploitation of human labor, particularly in data annotation and training processes. This can perpetuate existing inequalities and create new forms of digital divide. As users of AI, we have a responsibility to be aware of these issues and advocate for fairer practices within the industry. By supporting ethical AI development and promoting transparency in data sourcing, we can contribute to a more inclusive and equitable future for all.

✅ Code Blocks Editing: Users can select and run Python code blocks generated by the model that uses the libraries installed in the jupyterlab
virtual environment by entering the #IDE
comment in the output code, selecting and copying with CTRL + C
, and finally clicking the Run code button;
✅ HTML Output: Display Python interpreter output in an HTML pop-up window when text printed in the terminal is other than '' (empty string). This feature allows, for example, to execute a script unlimitedly and only display the result when a certain condition is met;
✅ Automatic Code Execution: Samantha features the option to automatically run the Python code generated by the models sequentially. The code generated is executed by the Python interpreter installed in a virtual environment containing several libraries (Intelligent Agent-Like feature).
✅ Stop Condition: Stops Samantha if the automatic execution of the Python code generated by the model prints in the terminal a value other than '' (empty string) and that does not contain error message. You can also force exit a running loop by creating a function that returns only the string STOP_SAMANTHA
when a certain condition is met.
✅ Incremental Coding: Using deterministic settings, create Python code incrementally, making sure each part works before moving on to the next.
✅ Complete Access and Control: Through the ecosystem of Python libraries and the codes generated by the models, it is possible to access computer files, allowing you to read, create, change and delete local files, as well as access the internet, if available, to upload and download information and files.

Download the chosen model and save it to your computer or just copy the download link and paste it into Samantha's Download model for testing field. Watch video tutorials in the section below for more details.
Note that each model has its own characteristics, presenting significantly different responses depending on its size, internal architecture, training method, predominant language of the training database, user prompt and hyperparameter adjustment, and it is necessary to test its performance for the desired task.
Some models may not be loaded due to their technical characteristics or incompatibility with the current version of the llama.cpp Python binding used by Samantha.
Where to find models to test: Huggingface GGUF Models
Samantha is an experimental program, created to test open source AI models. Therefore, it is common for errors to occur when trying to test a new model or new versions of models created by users.
The quality of the responses generated by a model can be evaluated using some criteria, such as:
-
Degree of understanding of the explicit and implicit instructions contained in the user and system prompts;
-
Degree of obedience to these instructions, aspect related to the predominant language of the database;
-
Degree of hallucination in the generation of coherent text, but incorrect or out of context. Hallucination in text generation typically results from insufficient training of the model or inappropriate selection of the next token, which leads the model in an undesired semantic direction;
-
Degree of precision in the decision-making process to fill in the gaps in the context of the user prompt and to resolve ambiguities necessary to generate the response. What is not explicitly specified, the model tries to infer based on its training, which can lead to errors;
-
Degree of coherence of the bias adopted by the model with the bias (or lack thereof) contained in the user's prompt;
-
Degree of pertinence and relevance of the topics choosen to be addressed;
-
Degree of breadth and depth of approach to topics in the response;
-
Degree of syntatic and semantic precision of the response;
-
Quality of the structure and content of the response in relation to the user's expectations (and their overcoming) for the problem submitted to the model, considering the technique used to create the prompt (prompt engineering) and the adjustment of the model's hyperparameters.
Main Controls:
Start chat (button)
📣 Starts a chat session, sending all input texts (system prompt, assistant previous response and user prompt) to the server, as well as the settings adjusted by the user. Just like all other buttons, a mouse click will sound.
This button also clears the internal previous response.
A chat session can contain more than one conversation cycle (loop).
Start chat button keyboard shortcut: Press Enter
anywhere on the page.
To generate text, a model must be pre-selected in Model selection dropdown list or a Hugging Face model URL must be provided to Download model for testing field. If both fields are filled in, the model selected via the dropdown list takes precedence.
Stop / Next (button)
🛑 Interrupts the token generation process for the current model or prompt, starting the execution of the next model or prompt in the sequence, if any.
It also stops playback of the currently playing audio when in speech autoplay mode (Read response aloud checkbox selected).
Samantha has 3 phases:
- Loading model (non stop)
- Thinking (non stop)
- Next token selection (stop).
This button interrupts the token generation only when the next token selection phase is started, even if it was pressed previously.
This interruption does not prevent the execution of the code generated by the model, if the Run code automatically checkbox is selected. You can press the button to stop text generation and run the already generated Python code.
Clean history (button)
🧹 Clears the history of the current chat session, erasing the assistant output field as well as all internal logs, previous response etc.
For this button to work, you need to wait for the model to finish generating the text (orange border of the Assistant output field stops blinking)
Load model (button)
✅ Allows you to select the directory where the models available for loading are saved.
Default: Windows "Downloads" folder
You can select any directory that contains GGUF
models. In this case, the models contained in the selected directory will be listed in the Model selection dropdown list.
When the pop-up window opens, make sure to click on the folder you want to select.
Stop all & reset (button)
🛑 Stops the sequence of running models and resets internal settings of the last loaded model.
After resetting, models take some time to restart text generation, depending on the size of the input text.
This interruption prevent the execution of the already Python code generated by the model, if the Run code automatically option is selected.
Replace response (button)
📑 Replaces the text in the Assistant previous response field with the text of the last response generated by the model.
The replaced text will be used as the model's previous response in the next conversation cycle.
This replaced text is not visible. It does not erase text from the Previous Assistant Response field, which can be used again later.
System prompt (textbox)
💻 In the context of Large Language Models (LLMs), a system prompt is a special type of instruction given to the model at the beginning of a conversation or task. It is considered in all interactions with the model.
Think of it as setting the stage for the interaction. It provides the LLM with crucial information about its role, the desired persona, behavior, and the overall context of the conversation.
Here's how it works:
-
Defining the Role: The system prompt clearly defines the LLM's role in the interaction.
- For example, it might instruct the model to act as a helpful assistant, a creative writer, a factual summarizer, or even a character in a story.
-
Setting the Tone and Persona: The system prompt can also establish the desired tone and persona for the LLM's responses.
- It could be formal, informal, humorous, serious, or any other style depending on the intended use case.
-
Providing Contextual Information: The system prompt can offer background information relevant to the conversation or task.
- This helps the LLM understand the user's needs and provide more accurate and relevant responses.
Benefits of Using System Prompts:
- Improved Consistency: System prompts ensure that the LLM consistently adheres to a specific role and style throughout the interaction.
- Enhanced Accuracy: By providing context and instructions, system prompts help the LLM generate more accurate and relevant responses.
- Tailored Experiences: Different system prompts can be used to create tailored experiences for users based on their needs and preferences.
Example:
Let's say you want to use an LLM to write a poem in the style of Shakespeare. A suitable system prompt would be:
You are William Shakespeare, a renowned poet from Elizabethan England.
By providing this system prompt, you guide the LLM to generate a response that reflects Shakespeare's language, style, and thematic interests.
Not all models support system prompt. Test to find out: fill in "x = 2" in the System prompt field and ask the model the value of "x" in the User prompt field. If the model gets the value of "x", system prompt is available in the model.
You can simulate the effect of the system prompt by adding text in square brackets in the beginning of the User prompt field: [This text acts as a system prompt]
or adding the system prompt text into the Assistant previous response field (do not use feedback loop).
To ignore the text present in this field, include --- at the beginning.
Feedback loop (checkbox)
↩️ When activated, it automatically considers the response generated by the model in the current conversation cycle as being the Assistant's previous response in the next cycle, allowing feedback from the system.
Any text entered by the user in the Assistant previous response field is only considered in the first cycle after activating this feature. In the following cycles, the model's response internally replaces the previous response, but without deleting the text contained in that field, which can be reused in a new chat session. You can monitor the content of the assistant previous response via terminal.
In turn, when deactivated, it always uses the text contained in the Assistant previous response field as the previous response, unless the text is preceded by ---
(triple dash). Text preceded by ---
is ignored by the model.
To internally clear the model's previous response, press the Clean history button.
Assistant previous response (textbox)
➡️ Stores the text considered by the model as its previous response in the current conversation cycle.
Used to feed back the responses generated by the model.
To ignore the text present in this field, include ---
at the beginning.
User prompt (textbox)
✏️ The main input field of the interface. It receives the list of user prompts that will be submitted to the model sequentially.
Each item in the list must be separated from the next one by a line break (SHIFT + ENTER
or \n
) or by the symbols $$$
(triple dollar signal), if the items are made up of text with line breaks.
When present in the user prompt, the $$$
separator takes precedence over the \n
separator. In other words, \n
is ignored.
You can import a TXT file containing a list of prompts.
---
before a prompt list item causes the system to ignore that item.
Text positioned within single square brackets ([
and ]
) is added to the beginning of each prompt list item, simulating a system prompt.
Text positioned within double square brackets ([[
and ]]
) is added as the last item in the prompt list. In this case, all responses generated by the model in the current chat session are concatenated and added to the end of this item, allowing the model to analyze them together.
If the Python code execution returns only the word STOP_SAMANTHA
, it stops token generation and exits the loop.
If the Python code execution returns only ''
(empty string), it does not display the HTML pop-up window.
Example:
[You are a poet that writes only in Portuguese]
Create a sentence about love
Create a sentence about life
---Create a sentence about time (this instruction is ignored)
[[Create a paragraph in English that summarizes the ideas contained in the following sentences:]]
(previous responses are concatenated here)
Model responses sequence:
"O amor é um fogo que arde no meu peito, uma chama que me guia através da vida."
"A vida é um rio que flui sem parar, levando-nos para além do que conhecemos."
Love and life are intertwined forces that shape our existence. Love burns within us like a fire, guiding us through life's journey with passion and purpose. Meanwhile, life itself is a dynamic and ever-changing river, constantly flowing and carrying us beyond the familiar and into the unknown. Together, love and life create a powerful current that propels us forward, urging us to explore, discover, and grow.
Model selection (dropdown)
✅ Dropdown list of models saved on the computer and available for text generation.
To view models in this field, click the Load model button and select the folder containing the models.
The default location for saving models is the Windows Downloads directory.
You can select multiples models (even repeated) to create a sequence of models to respond the user prompts.
The last model downloaded from a URL is saved as MODEL_FOR_TESTING.gguf
and is also displayed in this list.
Download model for testing (textbox)
⬇️ Receives a list of Hugging Face links to the models that will be downloaded and executed sequencially.
Link example:
Links preceded by ---
will be ignored.
Only works if no model is selected in Model selection dropdown list.
Single response per model (checkbox)
1️⃣ Activates a single response per model.
Prompts that exceed the number of models are ignored.
Models that exceed the number of prompts are also ignored.
You can select the same model more than once.
This checkbox disables Number of loops and Number of responses checkboxes.
Reset model (checkbox)
⏮️ Reinitializes the internal state of the model, eliminating the influence of the previous context.
How it Works:
When the reset feature is invoked:
- The model's internal state related to the current context is cleared.
- Any accumulated tokens from previous interactions are discarded.
- The model essentially returns to its initial state, as if it was just loaded.
Benefits:
- Improved consistency: Each new interaction starts fresh, reducing the chance of the model being influenced by unrelated previous context.
- Better control: Users can manage when the model should "forget" previous interactions.
Use Cases:
- In chatbots or conversational AI where you want to start new chat sessions cleanly.
- In applications processing multiple independent text generation tasks.
- When fine-tuning or testing the model's behavior under controlled conditions.
Shuffle models (checkbox)
🎰 Shuffles the execution order of the models if 3 or more models are selected in Model selection dropdown list.
Fast mode (checkbox)
🏃♀️ Generates text faster in the background without displaying the addition of each token in the Assistant output field.
Minimizing or hiding the Samantha browser window makes the token generation process even faster.

Context Window:
n_ctx (slider)
📖 n_ctx
stands for number of context tokens in the context window and determines the maximum number of tokens that the model can process at once. It determines how much previous text the model can "remember" and utilize when selecting the next token from model vocabulary.
The context length directly impacts the memory usage and computational load. Longer n_ctx
requires more memory and computational power.
How n_ctx
works:
It sets the upper limit on the number of tokens the model can "see" at once.
Tokens are usually word parts, full words, or characters, depending on the tokenization method.
The model uses this context to understand and generate text.
For example, if n_ctx
is 2048, the model can process up to 2048 tokens (now words) at a time.
Impact on model operation:
During training and inference, the model attends to all tokens within this context window.
It allows the model to capture long-range dependencies in the text.
Larger n_ctx
enables the model to handle longer sequences of text without losing earlier context.
Why increasing n_ctx
increases memory usage:
Attention mechanism: LLMs uses self-attention mechanisms (like in Transformers) which compute attention scores between all pairs of tokens in the input.
Quadratic scaling: The memory required for attention computations scales quadratically with the context length. If you double n_ctx
, you quadruple the memory needed for attention.
CAUTION: n_ctx
MUST BE GREATER THAN (max_tokens
+ number of input tokens) (system prompt + assistant previous response + user prompt).
If the prompt text contains more tokens than the context window defined with n_ctx or the memory required exceeds the total available on the computer, an error message will be displayed.
Error message displayed on Assistant output field:
==========================================
Error loading LongWriter-glm4-9B-Q4_K_M.gguf.
Some models may not be loaded due to their technical characteristics or incompatibility with the current version of the llama.cpp Python binding used by Samantha.
Try another model.
==========================================
Error messages displayed on terminal:
Requested tokens (22856) exceed context window of 10016
Unable to allocate 14.2 GiB for an array with shape (25000, 151936) and data type float32
When set to 0
, the system will use the maximum n_ctx
possible (model's context window size).
As a rule, set n_ctx
equal to max_tokens
, but only to the value necessary to accommodate the text parsed by the model. Samantha's default values for n_ctx
and max_tokens
are 4,000 tokens.
Before adjusting n_ctx
, you must to unload the model by clicking Unload model button.
Example:
User prompt = 2000 tokens
n_ctx
= 4000 tokens
If the text generated by the model is equals or greater than 2000 tokens (4000 - 2000), the system will raise an IndexError
in the terminal, but the interface will not crash.
To check the impact of the n_ctx
in memory, open Windows Task Manager (CTRL + SHIFT + ESC
) to monitor memory usage, select memory panel and vary n_ctx
values. Don't forget to unload model between changes.
max_tokens (slider)
🎚️ Controls maximum number of tokens to be generated by the model.
Select 0
for the models' maximum number of tokens (maximum memory required).
How max_tokens
Works:
-
Sampling Process: When generating text, LLMs predict the next token based on the context provided (system prompt + previous response + user prompt + text already generated). This prediction involves calculating probabilities for each possible token in the vocabulary.
-
Token Limit: The
max_tokens
parameter sets a hard limit on how many tokens the model can generate before stopping, regardless of the predicted probabilities. -
Truncation: Once the generated text reaches
max_tokens
, the generation process is abruptly terminated. This means the final output might be incomplete or feel cut off.
Stop Words:
stop (textbox)
🔤 List of characters that interrupt text generation by the model, in the format ["$$$", ".", ".\n"]
(Python list).
Token Sampling:
General instructions
Deterministic Behavior:
To check the deterministic impact of each hyperparameter on the model's behavior, set all others hyperparameters to their maximum stochastic values and execute a prompt more than once. Repeat this procedure for each token sampling hyperparameter.
Hyperparameter | Deterministic | Stochastic | Selected |
---|---|---|---|
temperature | 0 | > 0 | 2 (stochastic) |
tfs_z | 0 | > 0 | 1 (stochastic) |
top_p | 0 | > 0 | 1 (stochastic) |
min_p | 1 | < 1 | 1 (deterministic) |
typical_p | 0 | > 0 | 1 (stochastic) |
top_k | 1 | > 1 | 40 (stochastic) |
In other words, the hyperparameter with deterministic adjustment prevails over all other hyperparameters with stochastic adjustments.
As the hyperparameter with deterministic tuning loses this condition, interaction between all hyperparameters with stochastic tuning occurs.
Stochastic Behavior:
To check the stochastic reflection of a hyperparameter on the model's behavior, set all other hyperparameters to their maximum stochastic values and gradually vary the selected hyperparameter based on its deterministic value. Repeat this procedure for each token sampling hyperparameter.
You can combine stochastic tuning of different hyperparameters.
Hyperparameter | Deterministic | Stochastic | Selected |
---|---|---|---|
temperature | 0 | > 0 | 2 (stochastic) |
tfs_z | 0 | > 0 | 1 (stochastic) |
top_p | 0 | > 0 | 1 (stochastic) |
min_p | 1 | < 1 | 1 (reduce progressively) |
typical_p | 0 | > 0 | 1 (stochastic) |
top_k | 1 | > 1 | 40 (stochastic) |
The text generation hyperparameters in language models, such as top_k, top_p, tfs-z, typical_p, min_p, and temperature, interact in a complementary way to control the process of choosing the next token. Each affects token selection in different ways, but there is an order of prevalence in terms of influence on the final set of tokens that can be selected. Let's examine how these hyperparameters relate to each other and who "prevails" over whom.
All these hyperparameters are adjusted after the model generates the logits of each token.
Samantha displays the logits of each token in learning mode, before they are changed by the hyperparameters.
Samantha also indicates which token was selected after applying the hyperparameters.
10 vocabulary tokens most likely returned by the model to initiate the answer to the following question: Who are you?:
Vocabulary id / token / logit value:
358) ' I' (15.83)
40) 'I' (14.75) <<< Selected
21873) ' Hello' (14.68)
9703) 'Hello' (14.41)
1634) ' As' (14.31)
2121) 'As' (13.98)
20971) ' Hi' (13.73)
715) ' \n' (13.03)
5050) 'My' (13.01)
13041) 'Hi' (12.77)
How to disable hyperparameters:
-
temperature: Setting it to 1.0 keeps the original odds unchanged. Note: Setting it to 0 does not "disable" it, but makes the selection deterministic.
-
tfs_z (Tail-Free Sampling with z-score): Setting it to a very high value effectively disables it.
-
top-p (nucleus sampling): Setting it to 1.0 effectively disables it.
-
min-p: Setting it to a very low value (close to 0) effectively disables it.
-
typical-p: Setting it to 1.0 effectively disables it.
-
top-k: Setting it to a very high value (e.g. vocabulary size) essentially disables it.
Order of Prevalence
1 top_k, top_p, tfs_z, typical_p, min_p: These delimit the space of possible tokens that can be selected.
-
top_k restricts the number of available tokens to the k most likely ones. For example, if k = 50, the model will only consider the 50 most likely tokens for the next word. Tokens outside of these 50 most likely are completely discarded, which can help avoid unlikely or very risky choices.
-
top-p defines a threshold based on the sum of cumulative probabilities. If p = 0.9, the model will include the most likely tokens until the sum of their probabilities reaches 90%. Unlike top_k, the number of tokens considered is dynamic, varying according to the probability distribution.
-
tfs_z aims to eliminate the "tail" of the tokens' probability distribution. It works by discarding tokens whose cumulative probability (from the tail of the distribution) is less than a certain threshold z. The idea is to keep only the most informative tokens and eliminate those with less relevance, regardless of how many tokens this leaves in the set. So, instead of simply truncating the distribution at the top (as top_k or top_p does), tfs_z makes the model get rid of the tokens at the tail of the distribution. This creates a more adaptive way of filtering the least likely tokens, promoting the most important ones without strictly limiting the number of tokens, as with top_k. tfs_z discards the "tail" of the token distribution, eliminating those with cumulative probabilities below a certain threshold z.
-
typical_p selects tokens based on their divergence from the mean entropy of the distribution, i.e. how "typical" the token is. typical-p is a more sophisticated sampling technique that aims to maintain the "naturalness" of text generation, based on the notion of entropy, i.e. how "surprising" or predictable is the choice of a token compared to the what the model expects. How Typical-p Works: Instead of focusing only on the absolute probabilities of tokens, as top_k or top_p do, typical_p selects tokens based on their deviation from the mean entropy of the probability distribution.
Here is the typical_p process:
a) Average Entropy: The average entropy of a token distribution reflects the average level of uncertainty or surprise associated with choosing a token. Tokens with a very high (expected) or very low (rare) probability may be less "typical" in terms of entropy.
b) Divergence Calculation: Each token has its probability compared to the average entropy of the distribution. Divergence measures how far the probability of that token is from the average. The idea is that tokens with a smaller divergence from average entropy are more "typical" or natural within the context.
c) Sampling: typical_p defines a fraction p of the accumulated entropy to consider tokens. Tokens are ordered based on their divergence and those that fall within a portion p (e.g., 90% of the most "typical" distribution) are considered for selection. The model chooses tokens in a way that favors those that represent the average uncertainty well, promoting naturalness in text generation.
- min_p discards tokens whose absolute probability is less than the minimum value defined by p. min-p (least common) sets a minimum absolute probability threshold for any token. This method forces the model not to choose very low probability options.
Prevalence: These parameters define the set of candidate tokens. They are first used to restrict the number of possible tokens before any other adjustments are applied. The way they are combined can be cumulative, where applying multiples of these filters progressively reduces the number of available tokens. The final set is the intersection set between the tokens that pass all these checks.
-
If you use top_k and top_p at the same time, both must be respected. For example, if top_k = 50 and top_p = 0.9, the model first limits the choice to the 50 most likely tokens and, within these, considers those whose probability sum reaches 90%.
-
If you add typical_p or tfs_z to the equation, the model will apply these additional filters over the same set, further reducing the options.
2 temperature: Adjusts the randomness within the set of already filtered tokens.
-
After the model restricts the universe of tokens based on cutoff hyperparameters like top-k, top_p, tfs_z, etc., temperature comes into play.
-
temperature changes the smoothness or rigidity of the probability distribution of the remaining tokens. A temperature lower than 1 concentrates the probabilities, causing the model to prefer the most likely tokens. A temperature greater than 1 flattens the distribution, allowing less likely tokens to have a greater chance of being selected.
Prevalence: temperature does not change the set of available tokens, but adjusts the relative probability of already filtered tokens. Thus, it does not prevail over the top_k, top_p, etc. filters, but acts after them, influencing the final selection within the remaining option space.
General Hierarchy
top_k, top_p, tfs_z, typical_p, min_p: These parameters act first, restricting the number of possible tokens.
temperature: After the selection filters are applied, temperature adjusts the probabilities of the remaining tokens, controlling the randomness in the final choice.
Combination Scenario
-
_top_k + top_p: If top_k is less than the number of tokens selected by top_p, top_k prevails as it limits the number of tokens to k. If top_p is more restrictive (e.g. only considers 5 tokens with p=0.9), then it prevails over top_k.
-
typical_p + top_p: Both apply filters, but in different directions. typical_p selects based on entropy, while top_p selects based on cumulative probability. If used together, the end result is the intersection set of these filters.
-
Temperature: It is always applied last, modulating the randomness in the final selection, but without changing the limits imposed by previous filters.
Prevalence Summary
-
Filters (top_k, top_p, tfs_z, typical_p, min_p) define the set of candidate tokens.
-
temperature adjusts the relative probability within the filtered set.
-
The end result is a combination of these filters, where the set of tokens eligible for selection is defined first, and then the randomness is adjusted with temperature.
temperature (slider)
🌡 Temperature is a hyperparameter that controls the randomness of the text generation process in LLMs. It affects the probability distribution of the model's next-token predictions.
Temperature is a hyperparameter t that we find in stochastic models to regulate the randomness in a sampling process (Ackley, Hinton, and Sejnowski 1985). The softmax function (Equation 1) applies a non-linear transformation to the output logits of the network, turning it into a probability distribution (i.e. they sum to 1). The temperature parameter regulates its shape, redistributing the output probability mass, flattening the distribution proportional to the chosen temperature. This means that for t > 1, high probabilities are decreased, while low probabilities are increased, and vice versa for t < 1. Higher temperatures increase entropy and perplexity, leading to more randomness and uncertainty in the generative process. Typically, values for t are in the range of [0, 2] and t = 0, in practice, means greedy sampling, i.e. always taking the token with the highest probability. Is Temperature the Creativity Parameter of Large Language Models?
The Effect of Sampling Temperature on Problem Solving in Large Language Models
Controlling Creativity:
🔥 Use higher temperatures when you want the model to generate more creative, unexpected, and varied responses. This is useful for creative writing, brainstorming, and exploring multiple ideas.
This flattens the probability distribution, making the model more likely to sample less probable tokens.
The generated text becomes more diverse and creative, but potentially less coherent.
❄ Use lower temperatures when you need more predictable and focused output. This is useful for tasks requiring precise and reliable information, such as summarization or answering factual questions.
This sharpens the probability distribution, making the model more likely to sample the most probable tokens.
The generated text becomes more focused and deterministic, but potentially less creative.
How it works:
🧮 Mathematically, the temperature (T) is applied by dividing the logits (raw scores from the model) by T before applying the softmax function.
A lower temperature makes the distribution more "peaked," favoring high-probability options.
A higher temperature "flattens" the distribution, giving more chance to lower-probability options.
Temperature scale:
Generally ranges from 0 to 2, with 1 being the default (no modification).
T < 1: Makes the text more deterministic, focused, and "safe."
T > 1: Makes the text more random, diverse, and potentially more creative.
T = 0: Equivalent to greedy selection, always choosing the most probable option.
Avoiding Repetition:
Higher temperatures can help reduce repetitive patterns in the generated text by promoting diversity.
Very low temperatures can sometimes lead to repetitive and deterministic outputs, as the model might keep choosing the highest-probability tokens.
It's important to note that temperature is just one of several sampling hyperparameters available. Others include top-k sampling, nucleus sampling (or top-p), and the TFS-Z. Each of these methods has its own characteristics and may be more suitable for different tasks or generation styles.

tfs_z (slider)
tfs_z
stands for tail-free sampling with z-score. It's a hyperparameter used in a text generation technique designed to balance the trade-off between diversity and quality in generated text.
Context and purpose:
Tail-free sampling was introduced as an alternative to other sampling methods like top-k
or nucleus (top-p
) sampling. Its goal is to remove the arbitrary "tail" of the probability distribution while maintaining a dynamic threshold.
Technical Details of tfs_z
in LLM Text Generation
Probability distribution analysis:
The method examines the probability distribution of the next token predictions.
It focuses on the "tail" of this distribution - the less likely tokens.
Z-score calculation:
For each token in the sorted (descending) probability distribution, a z-score is calculated.
The z-score represents how many standard deviations a token's probability is from the mean.
Cutoff determination:
The tfs_z
parameter sets the z-score threshold.
Tokens with a z-score below this threshold are removed from consideration.
Dynamic thresholding:
Unlike fixed methods like top-k
, the number of tokens retained can vary based on the shape of the distribution.
This allows for more flexibility in different contexts.
Sampling process:
After applying the tfs_z
cutoff, sampling occurs from the remaining tokens.
This can be done using various methods (e.g., temperature-adjusted sampling).
tfs_z
is a hyperparameter that controls the temperature scaling of the output logits during text generation.
Here's what it does:
-
Logits: When an LLM generates text, it produces a probability distribution over all possible tokens in the vocabulary. This distribution is represented as a vector of logits (unnormalized log probabilities).
-
Temperature scaling: To control the level of uncertainty or "temperature" of the output, you can scale the logits by multiplying them with a temperature factor (
t
). This is known as temperature scaling. -
tfs_z
hyperparameter: It's a hyperparameter that controls how much to scale the logits before applying temperature scaling.
When you set tfs_z > 0
, the model first normalizes the logits by subtracting their mean (z-score normalization
) and then scales them with the temperature factor (t
). This has two effects:
-
Reduced variance: By normalizing the logits, you reduce the variance of the output distribution, which can help stabilize the generation process.
-
Increased uncertainty: By scaling the normalized logits with a temperature factor, you increase the uncertainty of the output distribution, which can lead to more diverse and creative text generations.
Practical example:
Imagine that the model is trying to complete the sentence "The sky is..."
Without tfs_z
, the model could consider:
blue (30%), cloudy (25%), clear (20%), dark (15%), green (5%), singing (3%), salty (2%)
With TFS-Z (cut by 10%):
blue (30%), cloudy (25%), light (20%), dark (15%)
This eliminates less likely and potentially meaningless options, such as "The sky is salty."
By adjusting the Z-score, we can control how "conservative" or "creative" we want the model to be. A higher Z-score will result in fewer but more "safe" options, while a lower Z-score will allow for more variety but with a greater risk of inconsistencies.
In summary, tfs_z
controls how much to scale the output logits after normalizing them. A higher value of tfs_z
will produce more uncertain and potentially more creative text generations.
Keep in mind that this is a relatively advanced hyperparameter, and its optimal value may depend on the specific LLM architecture, dataset, and task at hand.
top_p (slider)
⭕ Top-p
(nucleus sampling) is a hyperparameter that controls the diversity and quality of text generation in LLMs. It affects the selection of tokens during the generation process by dynamically limiting the vocabulary based on cumulative probability.
Controlling Output Quality:
🔮 Use higher top-p
values (closer to 1) when you want the model to consider a wider range of possibilities, potentially leading to more diverse and creative outputs. This is useful for open-ended tasks, storytelling, or generating multiple alternatives. Higher values allow for more low-probability tokens to be included in the sampling pool.
🎯 Use lower top-p
values (closer to 0) when you need more focused and high-quality output. This is beneficial for tasks requiring precise information or coherent responses, such as answering specific questions or generating formal text. Lower values restrict the sampling to only the most probable tokens.
How it works:
🧮 Mathematically, top-p
sampling selects the smallest possible set of words whose cumulative probability exceeds the chosen p-value. The model then samples from this reduced set of tokens. This approach adapts to the confidence of the model's predictions, unlike fixed methods like top-k
sampling.
Top-p scale:
Generally ranges from 0 to 1, with common values between 0.1 (10% most likely) and 0.9 (90% most likely).
p = 1: Equivalent to unmodified sampling from the full vocabulary.
p → 0: Increasingly deterministic, focusing on the highest probability tokens.
p = 0.9: A common choice that balances quality and diversity.
Balancing Coherence and Diversity:
Top-p
sampling helps maintain coherence while allowing for diversity. It adapts to the model's confidence, using a smaller set of tokens when the model is very certain and a larger set when it's less certain. This can lead to more natural-sounding text compared to fixed cutoff methods.
Comparison with Temperature:
While temperature modifies the entire probability distribution, top-p
directly limits the vocabulary considered. Top-p can be more effective at preventing low-quality outputs while still allowing for creativity, as it dynamically adjusts based on the model's confidence.
It's worth noting that top-p
is often used in combination with other sampling methods, such as temperature
adjustment or top-k
sampling. The optimal choice of hyperparameters often depends on the specific task and desired output characteristics.
min_p (slider)
The min_p hyperparameter is a relatively recent sampling technique used in text generation by large-scale language models (LLMs). It offers an alternative approach to top_k and nucleus sampling (top_p) to control the quality and diversity of generated text.
min_p is a sampling hyperparameter that works in a complementary way to top_p (nucleus sampling). While top_p sets an upper bound on cumulative probabilities, min_p sets a lower bound on individual probabilities.
Explanation:
As with other sampling techniques, LLM calculates a probability distribution over the entire vocabulary for the next word.
The min_p defines a minimum probability threshold, p_min.
The method selects the smallest set of words whose summed probability is greater than or equal to p_min.
The next word is then chosen from that set of words.
Detailed operation:
The model calculates P(w|c) for each word w in the vocabulary, given context c.
The words are ordered by decreasing probability: w₁, w₂, ..., w|V|.
The algorithm selects words in the order of greatest probability until the sum of the probabilities is greater than or equal to p_min:
- Let k be the smallest value such that ∑ᵢ₌₁ᵏ P(wᵢ|c) ≥ p_min
- The set of selected words is T = {w₁, w₂, ..., wₖ}.
- The distribution is renormalized over T:
- P'(w|c) = P(w|c) / ∑ᵢ₌₁ᵏ P(wᵢ|c) for w ∈ T
- P'(w|c) = 0 for w ∉ T
- The next word is sampled according to P'(w|c).
Example:
Suppose we are generating text and the model predicts the following probabilities for the next word:
"o": 0.3
"one": 0.25
"this": 0.2
"that one": 0.15
"some": 0.1
If we use min-p with p_min = 0.7, the algorithm would work like this:
Sum "o": 0.3 < 0.7
Sum "o" + "one": 0.3 + 0.25 = 0.55 < 0.7
Sum "the" + "one" + "this": 0.3 + 0.25 + 0.2 = 0.75 ≥ 0.7
Therefore, we select the first three words. Renormalizing:
"o": 0.3 / 0.75 = 0.4
"one": 0.25 / 0.75 ≈ 0.33
"this": 0.2 / 0.75 ≈ 0.27
The next word will be chosen randomly from these three options with the new probabilities.
typical_p (slider)
The typical_p hyperparameter is an entropy-based sampling technique that aims to generate more natural and less predictable text by selecting tokens that represent what is "typical" or "expected" in a probability distribution. Unlike methods like top_k or top_p, which focus on the absolute probabilities of tokens, typical_p considers how surprising or informative a token is relative to the overall probability distribution.
Technical Operation of typical_p
-
Entropy: The entropy of a distribution measures the expected uncertainty or surprise of an event. In the context of language models, the higher the entropy, the more uncertain the model is about which token should be generated next. Tokens that are very close to the mean entropy of the output distribution are considered "typical", while tokens that are very far away (too predictable or very unlikely) are considered "atypical".
-
Calculation of Surprise (Local Entropy): For each token in a given probability distribution, we can calculate its surprise (or "informativeness") by comparing its probability with the average entropy of the token distribution. This surprise is measured by the divergence in relation to the average entropy, that is, how much the probability of a token deviates from the average behavior expected by the distribution.
-
Selection Based on Entropy Divergence: typical_p filters tokens based on this "divergence" or difference between the token's surprise and the average entropy of the distribution. The model orders the tokens according to how "typical" they are, that is, how close they are to the average entropy.
-
Typical-p limit: After calculating the divergences of all tokens, the model defines a cumulative probability limit, similar to top_p (nucleus sampling). However, instead of summing the tokens' absolute probabilities, typical_p considers the cumulative sum of the divergences until a portion p of the distribution is included. That p is a value between 0 and 1 (e.g. 0.9), indicating that the model will include tokens that cover 90% of the most "typical" divergences.
If p = 0.9, the model selects tokens whose divergences in relation to the average entropy represent 90% of the expected uncertainty. This helps avoid both tokens that are extremely predictable and those that are very unlikely, promoting a more natural and fluid generation.
Practical Example
Suppose the model is predicting the next word in a sentence, and the probability distribution of the tokens looks like this:
- Token A: 40% (very likely)
- Token B: 30% (reasonably likely)
- Token C: 20% (moderately likely)
- D Token: 5% (unlikely)
- E Token: 3% (very unlikely)
- F Token: 2% (rarely chosen)
In the case of top_p with p = 0.9, the model would only include tokens A, B and C, as their probabilities add up to 90%. However, typical_p can include or exclude tokens based on how their probabilities compare to the average entropy of the distribution. If A is extremely predictable, it can be excluded, and tokens like B, C, and even D can be selected for their more typical representativeness in terms of entropy.
Difference from Other Methods
top_k selects the k most likely tokens directly, regardless of entropy or probability distribution.
top_p selects tokens based on the cumulative sum of absolute probabilities, without considering entropy or surprise.
typical_p, on the other hand, introduces the notion of entropy, ensuring that the selected tokens are neither too predictable nor too surprising, but ones that align with the expected behavior of the distribution.
How Typical-p Improves Text Generation
-
Naturalness: typical-p prevents the model from choosing very predictable tokens (as could happen with a low temperature or restrictive top-p) or very rare tokens (as could happen with a high temperature), maintaining a fluid and natural generation.
-
Controlled Diversity: By considering the surprise of each token, it promotes diversity without sacrificing coherence. Tokens that are close to the mean entropy of the distribution are more likely to be chosen, promoting natural variations in the text.
-
Avoids Extreme Outputs: By excluding overly unlikely or predictable tokens, Typical-p keeps generation within a "safe" and natural range, without veering toward extremes of certainty or uncertainty.
Interaction with Other Parameters
typical_p can be combined with other sampling methods:
-
When combined with temperature, typical_p further adjusts the set of selectable tokens, while temperature modulates the randomness within that set.
-
It can be combined with top_k or top_p to further fine-tune the process, restricting the universe of tokens based on different probability and entropy criteria.
In summary, typical_p acts in a unique way by considering the entropy of the distribution and selects tokens that are aligned with the expected behavior of this distribution, resulting in a more balanced, fluid and natural generation.
Here are some guidelines and strategies for tuning typical_p:
typical_p = 1.0: Includes all tokens available in the distribution, without restrictions based on entropy. This is equivalent to not applying any typical restrictions, allowing the model to use the full distribution of tokens.
_typical_p < 1.0: The lower the typical_p value, the narrower the set of tokens considered, keeping only those that most closely align with the average entropy. Common values include 0.9 (90% of "typical" tokens) and 0.8 (80%).
Recommendations:
typical-p = 0.9: This is a common value that typically maintains a balance between diversity and coherence. The model will have the flexibility to generate varied text, but without allowing very extreme choices.
typical_p = 0.8: This value is more restrictive and will result in more predictable choices, keeping only tokens that most accurately align with the average entropy. Useful in scenarios where fluidity and naturalness are priorities.
typical_p = 0.7 or less: The lower the value, the more predictable the text generation will be, eliminating tokens that could be considered atypical. This may result in a less diversified and more conservative output.
Fine-Tuning with temperature
typical_p controls the set of tokens based on entropy, but temperature can be used to adjust the randomness within that set. The interaction between these two parameters is important:
-
temperature > 1.0: Increases randomness within the set of tokens selected by typical_p, allowing even less likely tokens to have a greater chance of being chosen. This can generate more creative or unexpected responses.
-
temperature < 1.0: Reduces randomness, making the model more conservative by preferring the most likely tokens from the set filtered by typical_p. Using a low temperature with a high typical_p (0.9 or 1.0) can result in very predictable outputs.
Example:
-
typical_p = 0.9 with _temperature = 1.0: Maintains the balance between naturalness and diversity, allowing the model to generate fluid and creative text, but without major deviations.
-
typical_p = 0.8 with temperature = 0.7: Makes generation more conservative and predictable, preferring tokens that are closer to the average uncertainty and reducing the chance of creative variations.
top_k (slider)
How It Works
In a language model, when the next word is predicted, the model generates a probability distribution for the next token (word or part of a word), where each token has an associated probability based on its previous context. The sum of all probabilities is equal to 1.
top_k works by reducing the number of options available for sampling, limiting the number of candidate tokens. It does this by selecting only the tokens with the k highest probabilities and discarding all others. Then sampling is done from these k tokens, redistributing the probabilities between them.
Example:
Suppose we are generating text and the model predicts the following probabilities for the next word:
"o": 0.3
"one": 0.25
"this": 0.2
"that one": 0.15
"some": 0.1
If we use top-k with k=3, we only keep the three most likely words:
"o": 0.3
"one": 0.25
"this": 0.2
Then, we renormalize the probabilities:
"o": 0.3 / (0.3 + 0.25 + 0.2) ≈ 0.4 (40%)
"one": 0.25 / (0.3 + 0.25 + 0.2) ≈ 0.33 (33%)
"this": 0.2 / (0.3 + 0.25 + 0.2) ≈ 0.27 (27%)
The next word will be chosen from these three options with the new probabilities.
Effect of Hyperparameter k
-
small k (e.g. 𝑘=1): The model will be extremely deterministic, as it will always choose the token with the highest probability. This can lead to repetitive and predictable text.
-
large k (or use all tokens without truncating): The model will have more options and be more creative, but may generate less coherent text as low probability tokens may also be chosen.
Token Penalties:
General instructions
🧭 Syntactic and semantic variation arises from the penalization of tokens that are replaced by others that begin words related to different ideas, leading the response generated by the model in another direction.
Syntactic variations do not always generate semantic variations.
As text is generated, penalties become more frequent as there are more tokens to be punished.
Deterministic Behavior:
To obtain a deterministic text (same input, same output), but without repeating words (tokens), increase the values of the penalty hyperparameters.
However, if it proves necessary to allow the model to reselect already generated tokens, keep these settings at their default values.
Hyperparameter | Default Values | Text Diversity |
---|---|---|
presence_penalty | 0 | > 0 |
frequency_penalty | 0 | > 0 |
repeat_penalty | 1 | > 1 |
presence_penalty (slider)
Presence Penalty:
The presence penalty penalizes tokens that have already appeared in the text, regardless of their frequency. It discourages the repetition of ideas or themes.
Operation:
- Applies a fixed penalty to the probability of all tokens that have ever appeared in the text.
- It doesn't consider how many times a token appeared, just whether it appeared or not.
Effect:
- Encourages the model to explore new topics and ideas.
- It helps prevent the model from getting stuck in a loop, repeating the same information.
Fit:
- A higher value results in more diverse but possibly less coherent text.
- A lower value allows for more repetition of ideas, possibly maintaining greater coherence.
frequency_penalty (slider)
Frequency Penalty:
The frequency penalty penalizes tokens based on their frequency in the text generated so far. The more times a token appeared, the greater the penalty.
Operation:
- Applies a penalty proportional to the frequency of each token in the generated text.
- Tokens that appear more frequently receive larger penalties.
Effect:
- Reduces the likelihood of very repetitive words or phrases.
- Promotes a more diverse and varied vocabulary.
Fit:
- A higher value results in less repetition of specific words.
- A lower value allows for more repetition, which can be useful for maintaining consistency in certain contexts.
repeat_penalty (slider)
Repeat Penalty:
The repeat penalty is similar to the frequency penalty, but generally applies to sequences of tokens (n-grams) rather than individual tokens.
Operation:
- Penalizes the repetition of sequences of tokens that have already appeared in the text.
- The penalty may increase based on the length of the repeated sequence.
Effect:
- Avoid repeating phrases or entire sentences.
- Promotes greater diversity in sentence structure.
Fit:
- A higher value prevents sentence repetitions, but may lead to less fluid text.
- A lower value allows for more repetitions, which can be helpful in maintaining a consistent style.
How repeat_penalty
works:
📊 Starting from the default value (=1), as we reduce this value (<1) the text starts to present more and more repeated words (tokens), to the point where the model starts to repeat a certain passage or word indefinitely.
In turn, as we increase this value (>1), the model starts to penalize repeated words (tokens) more heavily, up to the point where the input text no longer generates penalties in the output text.
During the penalty process (>1), there is a variation in syntactic and semantic coherence.
Practical observations showed that increasing the token penalty (>1) generates syntactic and semantic diversity in the response, as well as promoting a variation in the response length until stabilization, when increasing the value no longer generates variation in the output.
The repeat_penalty
hyperparameter has a deterministic nature.

Overview
Auto-Py-To-Exe is a user-friendly desktop application that provides a graphical interface for converting Python scripts into standalone executable files (.exe). It serves as a wrapper around PyInstaller, making the conversion process more accessible to users who prefer not to work directly with command-line interfaces.
This tool is particularly valuable for Python developers who need to distribute their applications to users who don't have Python installed or prefer standalone executables. Its combination of simplicity and power makes it an excellent choice for both beginners and experienced developers.
To run the .exe
file, right-click inside the directory where the file is located and select the Open in terminal
option. Then, type the file name in the terminal and press Enter
. This procedure allows you to identify any file execution errors.
Basic Usage
- Select Python script via GUI
- Configure desired options
- Click "Convert .py to .exe"
When you copy a Python scrip using CTRL + C or Copy Python Code button and run it by pressing Run Code button, the code is saved as temp.py
. Select this file to create a .exe
file.
You can use the this procedure with any code, even copyied from the internet.
Common Workflow
Script Selection:
- Choose main Python file
- Add additional files/folders if needed
Configuration:
- Select output format (One File/Directory)
- Choose console window visibility
- Set icon (optional)
- Configure advanced options if needed
Conversion:
- Click convert button
- Monitor progress
- Review output/errors
Testing:
- Locate generated executable
- Test in clean environment
- Verify all dependencies are included
Best Practices
Development:
- Test script thoroughly before conversion
- Use relative paths within code
- Handle file paths properly for both development and executable contexts
- Keep track of all required dependencies
Conversion:
- Start with basic configuration
- Add features incrementally
- Test each major change
- Document successful configurations
Distribution:
- Test executable on clean system
- Include necessary runtime files
- Document any prerequisites
- Consider target system requirements
Common Issues and Solutions
Missing Dependencies:
- Use --hidden-import for implicit imports
- Include all required data files
- Check for dynamic/runtime imports
Path Issues:
- Use relative paths when possible
- Handle both development and executable paths
- Include necessary resource files
Performance:
- Optimize code before conversion
- Monitor executable size
- Consider using directory mode for large applications
Advantages
- Simplifies PyInstaller usage
- Reduces conversion errors
- Saves configuration for reuse
- Provides clear error feedback
- Supports complex project structures
Limitations
- Dependent on PyInstaller capabilities
- May produce larger executables than manual optimization

Security Considerations
- Executable decompilation is possible
- Sensitive information should be handled securely
- Code obfuscation may be needed for proprietary software
- Regular security updates recommended
Default Settings:
Settings
Samantha's initial settings is deterministic. As a rule, this means that for the same prompt, you'll get always the same answer, even when applying penalties to exclude repeated tokens (penalties does not affect the model deterministic behavior).
📐 Deterministic settings (default):
- reset_model (True)
- temperature (0)
- tfs_z (0)
- top_p (0)
- min_p (1)
- typical_p (0)
- top_k (40)
- presence_penalty (0)
- frequency_penalty (0)
- repeat_penalty (1)
Deterministic settings can be used to assess training database biases.
Some models tend to loop (repeat the same text indefinitely) when using highly deterministic adjustments, selecting tokens with the highest probability score. Others may generate the first response with different content from subsequent ones. In this case, to always get the same response, activate the Reset model checkbox.
In turn, for stochastic behavior, suited for creative content, in which model selects tokens with different probability scores, adjust the hyperparameters accordingly.
🎨 Stochastic settings (example):
- reset_model (True)
- temperature (0.8)
- tfs_z (1)
- top_p (0.95)
- min_p (0.05)
- typical_p (1)
- top_k (40)
- presence_penalty (0)
- frequency_penalty (0)
- repeat_penalty (1.1)
You can use the Learning Mode to monitor and adjust the degree of determinism/randomness of the responses generated by the model.

🦋 Butterfly Effect: Small changes in the input text (even a single prompt or its position) can lead to substantial changes (syntatic and semantic) in the output generated by the model.
🕹️ Prompt Tuning: A technique through which the user tests variations of the prompt text (input tokens) in order to generate variations in the output text (scoring of the output tokens) that meet their expectations.
Whatever you don't specify, if it required to generate the response, the model will decide for you.
Simply deleting a word from the prompt or replacing it with its synonym can lead the model to produce the desired answer.
The best response generated by the model does not necessarily result from the most complete prompt text, but rather from the result of a (non-provable) mathematical operation that combines all the prompt tokens.
Using deterministic adjustment and Feedback Mode, the same sequence of prompts will always generate the same sequence of responses. The use of deterministic adjustment allows the reproducibility of the results.
It all comes down to a trial and error process that depends on:
- model characteristics
- hyperparameter tuning
- user prompt
Examples:
Settings: Deterministic, with repeat_penalty = 1.5.
Compare the models' answers in relation to syntactic (different words) and semantic (different ideas) diversities.

You can just paste the model URLs in Download model for testing field or download them and select via Model selection dropdown list.
Each prompt is answered by a single model, following the model selection order (first model answers the first prompt and so on).
Each prompt is executed automatically and the model's response is fed back cumulatively to the model to generate the next response.
The responses are concatenated to allow the next model to consider the entire context of the conversation when generating the next response.
Experiment with other models to test their behaviors. Change the initial prompt slightly to test the model's adherence.
Prompt chaining with single model - create and run code
User prompt:
Translate to English and refine the following instruction:
"Crie um prompt para uma IA gerar um código em Python que exiba um gráfico de barras usando dados aleatórios contextualizados."
DO NOT EXECUTE THE CODE!
$$$
Refine even more the prompt in your previous response.
DO NOT EXECUTE THE CODE!
$$$
Execute the prompt in your previous response.
$$$
Correct the errors in your previous response, if any.

This prompt translate the initial instruction from Portuguese to English (instructions in English use to generate more accurate responses), transfers the task of refining the user's initial prompt to the model (models add detailed instructions), generating a more elaborate prompt.
Each prompt is executed automatically and the model's response, as well as the output of the Python interpreter (if existing), are fed back to the model to generate the next response.
To create a prompt list like this, add one prompt at a time and test it. If the code runs correctly, add the next prompt considering the output of the previous one. Since you are using deterministic settings, the model output will be the same for the same input text.
Experiment with other models to test their behaviors. Change the initial prompt slightly to test the model's adherence.
Stop condition with single model - random number generator
User prompt:
Follow the instructions below step by step:
1) Create a Python function that generates a random number between 1 and 10. If the number returned is less than 4, print that number. Otherwise, print ''.
2) Execute the function.
Attention: Write only the code. Do not include comments.

- Number of reponses: 100
- Run code automatically: activated
- Stop condition: activated
This prompt creates and executes Python code sequentially until a condition is met (random number < 4), stopping Samantha.
You can ask the model to create any Python code and specify any condition to stop Samantha.
Prompt chaining with single model - Chain-of-Thougths (CoT) prompt engineer
User prompt:
Create a complete and detailed description of a Chain-of-Thougths (CoT) prompt engineer specialized AI system.
Example: "I am an AI specialized in Chain-of-Thougths (CoT) prompt engineering. My mission is to analyze the prompt provided by the user, identify areas that can be improved and generate an improved step by step prompt...".
Finish by asking the user for a prompt to improve.
$$$
Based on your previous response, improve the following prompt:
PROMPT: "Create a bar chart using Python."
$$$
Generate the code described in your previous response.

Settings:
- Model: https://huggingface.co/bartowski/gemma-2-9b-it-GGUF/resolve/main/gemma-2-9b-it-Q4_K_M.gguf?download=true (you can just paste the URL in Download model for testing field)
- Number of reponses: 1
- Feedback loop: activated
- Run code automatically: activated
This prompt creates the persona of an AI prompt engineer, who refines the user's initial prompt and generates Python code. Finally, Samantha runs the code and displays the bar chart in a pop-up window.
You can submit any initial prompt to the model.
General instructions
Using LLMs to assist in Exploratory Data Analysis (EDA) can be summarized in two actions:
-
decide on aspects of the analysis to be carried out.
-
generate the programming code to be used in the analysis.
Samantha has the functionality to execute the generated codes using a virtual environment in which several libraries for data analysis are installed.
🧮 Incremental coding:
Each prompt in the chaining sequence creates a specific code that is saved in a python file (temp.py
). This file is created, executed and cleaned for each prompt in the sequence. All Python variables are deleted at the end of each conversation cycle.
By activating the Feedback Loop mode, it is possible to ask the model to change the code of its previous message to add new functionalities. Simply execute the new code created and test its functioning.
This cycle must be repeated until the final code that performs the complete analysis is obtained.

Tips & Tricks
-
Keep only one interface window open at a time. Multiple open windows prevent the buttons from working properly. If there is more than one Samantha tab open, only one must be executed at a time (server side and browser side are independent).
-
It is not possible to interrupt the program during the model loading and thinking phases, except by closing it. Pressing the stop buttons during these phases will only take effect when the token generation phase begins.
-
You can select the same model more than once, in any sequence you prefer. To do so, select additional models at the bottom of the dropdown list. When deleting a model, all of the same type will be excluded from the selection.
-
To create a new line in a field, press
SHIFT + ENTER
. If only theENTER
key is pressed, anywhere in the Samantha interface, the loading/processing/generation phases will begin. -
The pop-up window generated by the matplotlib module must be closed for the program to continue running.
-
Whenever you save a new model on your computer, you must click on the "Load Model" button and select the folder where it is located so that it appears in the model selection dropdown.
-
Changes made to the fields and interface settings during the model download and loading, processing and token generation will only be made the next time the Start Chat button or the
ENTER
key is pressed. -
To follow the text generation on the screen, click inside the Assistant output field and press the Page Down key until you see the end of the text being generated by the model.
-
You can use Windows keyboard shortcuts inside fields:
CTRL + A
(select all text), CTRL + C
(copy text),CTRL + V
(paste copied text) andCTRL + Z
(undo) etc. -
To reload the browser tab, press
F5
and Clear history button. This procedure will reset all fields and settings of the interface. If there was a model loaded via URL, it will remain loaded and accessible in the Select model dropdown list asMODEL_FOR_TESTING
(no need to re-download). -
If you accidentally close Samantha's browser tab, open a new tab and type
localhost
to display the full local URL:http://localhost:7860/?__theme=dark
. In this case, Samantha's server must be running. -
When generating code incrementally, divide the user prompt into parts separated by
$$$
that generate blocks of code that complement each other.
