A Local GenAI API Server: A drop-in replacement for OpenAI's API for Local GenAI

| Documentation | Blog | Discord | Roadmap |

EdgenChat, a local chat app powered by ⚡Edgen

• [x] OpenAI Compliant API: ⚡Edgen implements an OpenAI compatible API, making it a drop-in replacement.
• [x] Multi-Endpoint Support: ⚡Edgen exposes multiple AI endpoints such as chat completions (LLMs) and speech-to-text (Whisper) for audio transcriptions.
• [x] Model Agnostic: LLMs (Llama2, Mistral, Mixtral...), Speech-to-text (whisper) and many others.
• [x] Optimized Inference: You don't need to take a PhD in AI optimization. ⚡Edgen abstracts the complexity of optimizing inference for different hardware, platforms and models.
• [x] Modular: ⚡Edgen is model and runtime agnostic. New models can be added easily and ⚡Edgen can select the best runtime for the user's hardware: you don't need to keep up about the latest models and ML runtimes - ⚡Edgen will do that for you.
• [x] Model Caching: ⚡Edgen caches foundational models locally, so 1 model can power hundreds of different apps - users don't need to download the same model multiple times.
• [x] Native: ⚡Edgen is built in 🦀Rust and is natively compiled to all popular platforms: Windows, MacOS and Linux. No docker required.
• [ ] Graphical Interface: A graphical user interface to help users efficiently manage their models, endpoints and permissions.

⚡Edgen lets you use GenAI in your app, completely locally on your user's devices, for free and with data-privacy. It's a drop-in replacement for OpenAI (it uses the a compatible API), supports various functions like text generation, speech-to-text and works on Windows, Linux, and MacOS.

Features

• [x] Session Caching: ⚡Edgen maintains top performance with big contexts (big chat histories), by caching sessions. Sessions are auto-detected in function of the chat history.
• [x] GPU support: CUDA, Vulkan. Metal

Endpoints

• [x] [Chat] Completions
• [x] [Audio] Transcriptions
• [x] [Embeddings] Embeddings
• [ ] [Image] Generation
• [ ] [Chat] Multimodal chat completions
• [ ] [Audio] Speech

🔥 Hot Topics

Why local GenAI?

• Data Private: On-device inference means users' data never leave their devices.

• Scalable: More and more users? No need to increment cloud computing infrastructure. Just let your users use their own hardware.

• Reliable: No internet, no downtime, no rate limits, no API keys.

• Free: It runs locally on hardware the user already owns.

Quickstart

⚡Edgen usage:

Usage: edgen [<command>] [<args>]

Toplevel CLI commands and options. Subcommands are optional. If no command is provided "serve" will be invoked with default options.

Options:
  --help            display usage information

Commands:
  serve             Starts the edgen server. This is the default command when no
                    command is provided.
  config            Configuration-related subcommands.
  version           Prints the edgen version to stdout.
  oasgen            Generates the Edgen OpenAPI specification.

edgen serve usage:

Usage: edgen serve [-b <uri...>] [-g]

Starts the edgen server. This is the default command when no command is provided.

Options:
  -b, --uri         if present, one or more URIs/hosts to bind the server to.
                    `unix://` (on Linux), `http://`, and `ws://` are supported.
                    For use in scripts, it is recommended to explicitly add this
                    option to make your scripts future-proof.
  -g, --nogui       if present, edgen will not start the GUI; the default
                    behavior is to start the GUI.
  --help            display usage information

GPU Support

⚡Edgen also supports compilation and execution on a GPU, when building from source, through Vulkan, CUDA and Metal. The following cargo features enable the GPU:

• llama_vulkan - execute LLM models using Vulkan. Requires a Vulkan SDK to be installed.
• llama_cuda - execute LLM models using CUDA. Requires a CUDA Toolkit to be installed.
• llama_metal - execute LLM models using Metal.
• whisper_cuda - execute Whisper models using CUDA. Requires a CUDA Toolkit to be installed.

Note that, at the moment, llama_vulkan, llama_cuda and llama_metal cannot be enabled at the same time.

Example usage (building from source, you need to first install the prerequisites):

cargo run --features llama_vulkan --release -- serve
