With [OpenAI's ChatCompletion API](https://platform.openai.com/docs/api-reference/chat/), you can pass in a function schema in the `functions` keyword arg, and the API response will include a `function_call` field that includes the function name and the function arguments (generated JSON). How this works under the hood is your `functions` keyword is combined with the `messages` and `system` to form one big string input to the transformer, and the output of the transformer is parsed to extract the JSON function call. - -In the future, more open LLMs and LLM servers (that can host OpenAI-compatible ChatCompletion endpoints) may start including parsing code to do this automatically as standard practice. However, in the meantime, when you see a model that says it supports “function calling”, like Airoboros, it doesn't mean that you can just load Airoboros into a ChatCompletion-compatible endpoint like WebUI, and then use the same OpenAI API call and it'll just work. - -1. When a model page says it supports function calling, they probably mean that the model was fine-tuned on some function call data (not that you can just use ChatCompletion with functions out-of-the-box). Remember, LLMs are just string-in-string-out, so there are many ways to format the function call data. E.g. Airoboros formats the function schema in YAML style (see https://huggingface.co/jondurbin/airoboros-l2-70b-3.1.2#agentfunction-calling) and the output is in JSON style. To get this to work behind a ChatCompletion API, you still have to do the parsing from `functions` keyword arg (containing the schema) to the model's expected schema style in the prompt (YAML for Airoboros), and you have to run some code to extract the function call (JSON for Airoboros) and package it cleanly as a `function_call` field in the response. - -2. Partly because of how complex it is to support function calling, most (all?) of the community projects that do OpenAI ChatCompletion endpoints for arbitrary open LLMs do not support function calling, because if they did, they would need to write model-specific parsing code for each one. - -### What is this all this extra code for? - -Because of the poor state of function calling support in existing ChatCompletion API serving code, we instead provide a light wrapper on top of ChatCompletion that adds parsers to handle function calling support. These parsers need to be specific to the model you're using (or at least specific to the way it was trained on function calling). We hope that our example code will help the community add additional compatability of Letta with more function-calling LLMs - we will also add more model support as we test more models and find those that work well enough to run Letta's function set. diff --git a/docs/api.md b/docs/api.md deleted file mode 100644 index a37db098d4..0000000000 --- a/docs/api.md +++ /dev/null @@ -1,161 +0,0 @@ ---- -title: Using the Letta API -excerpt: How to set up a local Letta API server -category: 658135e7f596b800715c1cee ---- - -![letta llama](https://raw.githubusercontent.com/cpacker/Letta/main/docs/assets/letta_server.webp) - -> ⚠️ API under active development -> -> The Letta API is under **active development** and **changes are being made frequently**. -> -> For support and to track ongoing developments, please visit [the Letta Discord server](https://discord.gg/9GEQrxmVyE) where you can chat with the Letta team and other developers about the API. - -Letta can be run as a (multi-user) server process, allowing you to interact with agents using a REST API and use Letta to power your LLM apps. - -## Before getting started - -To run the Letta server process, you'll need to have already installed and configured Letta (you must have already run `letta configure` or `letta quickstart`). - -Before attempting to launch a server process, make sure that you have already configured Letta (using `letta configure`) and are able to successfully create and message an agent using `letta run`.

Assuming you edited things correctly, you should now be able to run `agent_groupchat.py`: - -```sh -python letta/autogen/examples/agent_groupchat.py -``` - -Your output should look something like this: - -```text -User_proxy (to chat_manager): - -I want to design an app to make me one million dollars in one month.

It's used to handle context beyond limited context windows, which is crucial for tasks such as extended conversations and document analysis. The technique was inspired by hierarchical memory systems in traditional operating systems that provide the appearance of large memory resources through data movement between fast and slow memory. This system intelligently manages different memory tiers to effectively provide extended context within the model's limited context window. - --------------------------------------------------------------------------------- -... -``` diff --git a/docs/cli_faq.md b/docs/cli_faq.md deleted file mode 100644 index 0a8da06d49..0000000000 --- a/docs/cli_faq.md +++ /dev/null @@ -1,68 +0,0 @@ ---- -title: Frequently asked questions (FAQ) -excerpt: Check frequently asked questions -category: 6580d34ee5e4d00068bf2a1d ---- - -> 📘 Open / local LLM FAQ -> -> Questions specific to running your own open / local LLMs with Letta can be found [here](local_llm_faq). - -## Letta CLI - -### How can I use Letta to chat with my docs? - -Check out our [chat with your docs example](example_data) to get started. - -### How do I save a chat and continue it later? - -When you want to end a chat, run `/exit`, and Letta will save your current chat with your agent (make a note of the agent name, e.g. `agent_N`). Later, when you want to start a chat with that same agent, you can run `letta run --agent `. - -### How do I implement Letta for multiple users? -The REST API for [Letta](https://letta.readme.io/reference/api) is flexible and leverages PostgreSQL DB or SQLite for its backend. To implement a multi-user setup, first determine the user_id (either create a UUID or use the user_id from your own database). Then [create an agent](https://letta.readme.io/reference/create_agent_api_agents_post), and finally use the agent_id and user_id to post a message or run a command. Internally the following occurs: -* a user creates an agent -* that agent is "owned" by a user -* when the user sends the agent a message, that's stored in a message collection (messages are indexed by user and agent ids) -* on the higher-level agents side (not talking about db implementation details), the agent can only see a few messages at a time, but has access to all the messages ever sent between it and the user via the recall memory search functions -* the database is multi-user, and the REST endpoints function in a way where user data is not shared - -### My Letta agent is stuck "Thinking..." on the first message? - -Letta has an extra verification procedure on the very first message to check that in the first message (1) the agent is sending a message to the user, and (2) that the agent is using internal monologue. This verification is meant to avoid the scenario where a bad initial agent message "poisons" the rest of a conversation. For example, a message missing internal monologue might cause all future messages to also omit internal monologue. - -If the LLM/model you're using for Letta is consistently failing the first message verification, it will appear as a long "Thinking..." loop on the first message. "Weaker" models such as `gpt-3.5-turbo` can frequently fail first message verification because they do not properly use the `send_message` function and instead put the message inside the internal monologue. Better models such as `gpt-4` and `gpt-4-turbo`, as well as open models like `dolphin-2.2.1` and `openhermes-2.5` should not have this problem. - -You can disable first message verification by passing the `--no-verify` flag to `letta run` (do `letta run --no-verify` instead of `letta run`). Passing the additional `--debug` flag (`letta run --no-verify --debug`) can help you further identify any other issues on first messages that can cause long "Thinking..." loops, such as rate limiting. - -### What are personas and how they relate to agents and humans? -Letta has two core components: agents and humans. Each human contains information about the user that is continously updated as Letta learns more about that user. Agents are what the human interacts with when they chat with Letta. Each agent can be customized through presets which are basically the configuration for an agent and includes the following componenets: -* system prompt (you usually don't change this) -* persona (personality of your bot and their initial memories) -* human (description of yourself / user details) -* functions (the functions the agent can call during convo) - -### I broke/corrupted my agent, how can I restore an earlier checkpoint? - -Letta saves agent checkpoints (`.json` files) inside the `~/.letta/agents/YOUR_AGENT_NAME/agent_state` directory (`C:\Users\YourUsername\.letta\YOUR_AGENT_NAME\agent_state` on Windows). By default, when you load an agent with `letta run` it will pull the latest checkpoint `.json` file to load (sorted by date). - -If you would like to revert to an earlier checkpoint, if you remove or delete other checkpoint files such that the specific `.json` from the date you would like you use is the most recent checkpoint, then it should get automatically loaded by `letta run`. We recommend backing up your agent folder before attempting to delete or remove checkpoint files. - -## OpenAI-related - -### How do I get an OpenAI key? - -To get an OpenAI key, visit [https://platform.openai.com/](https://platform.openai.com/), and make an account. - -Then go to [https://platform.openai.com/account/api-keys](https://platform.openai.com/account/api-keys) to create an API key.

Create a new preset that imports these functions (and optionally uses the new system prompt) - -### Simple example: giving Letta the ability to roll a D20 - -> ⚠️ Function requirements -> -> The functions you write MUST have proper docstrings and type hints - this is because Letta will use these docstrings and types to automatically create a JSON schema that is used in the LLM prompt. Use the docstrings and types annotations from the [example functions](https://github.com/cpacker/Letta/blob/main/letta/functions/function_sets/base.py) for guidance. - -> ⚠️ Function output length -> -> Your custom function should always return a string that is **capped in length**. If your string goes over the specified limit, it will be truncated internally. This is to prevent potential context overflows caused by uncapped string returns (for example, a rogue HTTP request that returns a string larger than the LLM context window). -> -> If you return any type other than `str` (e.g. `dict``) in your custom functions, Letta will attempt to cast the result to a string (and truncate the result if it is too long). It is preferable to return strings - think of your function returning a natural language description of the outcome (see the D20 example below). - -In this simple example we'll give Letta the ability to roll a [D20 die](https://en.wikipedia.org/wiki/D20_System). - -First, let's create a python file `~/.letta/functions/d20.py`, and write some code that uses the `random` library to "roll a die": - -```python -import random - - -def roll_d20(self) -> str: - """ - Simulate the roll of a 20-sided die (d20). - - This function generates a random integer between 1 and 20, inclusive, - which represents the outcome of a single roll of a d20. - - Returns: - int: A random integer between 1 and 20, representing the die roll. - - Example: - >>> roll_d20() - 15 # This is an example output and may vary each time the function is called. - """ - dice_role_outcome = random.randint(1, 20) - output_string = f"You rolled a {dice_role_outcome}" - return output_string -``` - -Notice how we used [type hints](https://docs.python.org/3/library/typing.html) and [docstrings](https://peps.python.org/pep-0257/#multi-line-docstrings) to describe how the function works. **These are required**, if you do not include them Letta will not be able to "link" to your function. This is because Letta needs a JSON schema description of how your function works, which we automatically generate for you using the type hints and docstring (which you write yourself). - -Next, we'll create a custom preset that includes this new `roll_d20` function.

For example, the `dolphin-2.1-mistral-7b` model works better with the `airoboros-l2-70b-2.1` wrapper than the `dolphin-2.1-mistral-7b` wrapper. The model you load inside your LLM backend (e.g. LM Studio) determines what model is actually run, the `--model-wrapper` flag just determines how the prompt is formatted before it is passed to the LLM backend. - -### Grammars - -Grammar-based sampling can help improve the performance of Letta when using local LLMs. Grammar-based sampling works by restricting the outputs of an LLM to a "grammar", for example, the Letta JSON function call grammar. Without grammar-based sampling, it is common to encounter JSON-related errors when using local LLMs with Letta. - -To use grammar-based sampling, make sure you're using a backend that supports it: webui, llama.cpp, or koboldcpp, then you should specify one of the new wrappers that implements grammars, eg: `airoboros-l2-70b-2.1-grammar`. - -Note that even though grammar-based sampling can reduce the mistakes your LLM makes, it can also make your model inference significantly slower. - -### Supported backends - -Currently, Letta supports the following backends: - -* [oobabooga web UI](webui) (Mac, Windows, Linux) (✔️ supports grammars) -* [LM Studio](lmstudio) (Mac, Windows) (❌ does not support grammars) -* [koboldcpp](koboldcpp) (Mac, Windows, Linux) (✔️ supports grammars) -* [llama.cpp](llamacpp) (Mac, Windows, Linux) (✔️ supports grammars) -* [vllm](vllm) (Mac, Windows, Linux) (❌ does not support grammars) - -If you would like us to support a new backend, feel free to open an issue or pull request on [the Letta GitHub page](https://github.com/cpacker/Letta)! - -### Which model should I use? - -> 📘 Recommended LLMs / models -> -> To see a list of recommended LLMs to use with Letta, visit our [Discord server](https://discord.gg/9GEQrxmVyE) and check the #model-chat channel. - -Most recently, one of the best models to run locally is Meta's [Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) or its quantized version such as [Meta-Llama-3-8B-Instruct-Q6_K.gguf](https://huggingface.co/bartowski/Meta-Llama-3-8B-Instruct-GGUF). - -If you are experimenting with Letta and local LLMs for the first time, we recommend you try the Dolphin Mistral finetune (e.g. [ehartford/dolphin-2.2.1-mistral-7b](https://huggingface.co/ehartford/dolphin-2.2.1-mistral-7b) or a quantized variant such as [dolphin-2.2.1-mistral-7b.Q6_K.gguf](https://huggingface.co/TheBloke/dolphin-2.2.1-mistral-7B-GGUF)), and use the default `airoboros` wrapper. - -Generating Letta-compatible outputs is a harder task for an LLM than regular text output. For this reason **we strongly advise users to NOT use models below Q5 quantization** - as the model gets worse, the number of errors you will encounter while using Letta will dramatically increase (Letta will not send messages properly, edit memory properly, etc.). - -> 📘 Advanced LLMs / models -> -Enthusiasts with high-VRAM GPUS (3090,4090) or apple silicon macs with >32G VRAM might find [IQ2_XS quantization of Llama-3-70B](https://huggingface.co/MaziyarPanahi/Meta-Llama-3-70B-Instruct-GGUF) interesting, as it is currently the highest-performing opensource/openweights model.

Run the script from the root project directory: - - ```sh - bash db/run_postgres.sh - ``` - -5. Configure Letta to use Postgres - -```sh -letta configure -``` - -and selecting `postgres` for archival storage, and enter the approporate connection string.

You do not need to do this manually if you use our Docker container, however. - - -## Chroma - -You can configure Chroma with both the HTTP and persistent storage client via `letta configure`. You will need to specify either a persistent storage path or host/port dependending on your client choice. The example below shows how to configure Chroma with local persistent storage: - -```text -? Select LLM inference provider: openai -? Override default endpoint: https://api.openai.com/v1 -? Select default model (recommended: gpt-4): gpt-4 -? Select embedding provider: openai -?

You can set an API key for authentication with a Qdrant server using the `QDRANT_API_KEY` environment variable. Learn more about setting up Qdrant [here](https://qdrant.tech/documentation/guides/installation/). - -```sh -? Select Qdrant backend: server -?
