SimpleAI

A self-hosted alternative to the not-so-open AI API. It mostly focus on replicating the main endpoints for LLM:

• Text completion
• Chat
• Edits

While it is not an exact replication of the original endpoints, it should be relatively to switch from one to the other, allowing you to experiment with competing approaches quickly and easily.

Installation

On a machine with Python 3.11+, simply navigate in the root directory and use:

pip install -r requirements.txt

There is alternatively a Dockerfile you can use to build an image and execute within a container.

Setup

Copy the template models.toml.template and create models.toml : that will be where you declare your different models.

Once this is done, you can start adding your models, but in the meantime you can already start a server locally with:

uvicorn app:app --reload

Integrating and declaring a model

Models are queried through gRPC, in order to separate the API itself from the model inference, and to support several languages beyond Python through this protocol.

To add a model, you first need to deploy a gRPC service (using the provided .proto file and / or the templates provided in src/serve). Once your model is live, you only have to add it to the models.toml configuration file. For instance, let's say you've locally deployed a [llama.cpp] model available on port 50051, just add:

[llama-7B-4b]
    [llama-7B-4b.metadata]
        owned_by    = 'Meta'
        permission  = []
        description = 'C++ implementation of Meta's LlaMA model, 7B parameters, 4-bit quantization'
    [llama-7B-4b.network]
        url = 'localhost:50051'

This is very much work in progress and ugly, so let me know if you want to help. PR, issues, documentation, cool logo, all the usual candidates are welcome.
