Serge - LLaMA made easy 🦙

A chat interface based on llama.cpp for running Alpaca models. Entirely self-hosted, no API keys needed. Fits on 4GB of RAM and runs on the CPU.

• SvelteKit frontend
• Redis for storing chat history & parameters
• FastAPI + langchain for the API, wrapping calls to llama.cpp using the python bindings

Getting started

Setting up Serge is very easy. Starting it up can be done in a single command:

docker run -d -v weights:/usr/src/app/weights -v datadb:/data/db/ -p 8008:8008 ghcr.io/nsarrazin/serge:latest

Then just go to http://localhost:8008/ and you're good to go!

The API documentation can be found at http://localhost:8008/api/docs

Windows

Make sure you have docker desktop installed, WSL2 configured and enough free RAM to run models. (see below)

Kubernetes & docker compose

Setting up Serge on Kubernetes or docker compose can be found in the wiki: https://github.com/nsarrazin/serge/wiki/Integrating-Serge-in-your-orchestration#kubernetes-example

Models

Currently the following models are supported:

• Alpaca 7B
• Alpaca 7B-native
• Alpaca 13B
• Alpaca 30B
• GPT4All
• Vicuna 7B
• Vicuna 13B
• Open Assistant 13B
• Open Assistant 30B

If you have existing weights from another project you can add them to the serge_weights volume using docker cp.

⚠️ A note on memory usage

LLaMA will just crash if you don't have enough available memory for your model.

• 7B requires about 4.5GB of free RAM
• 13B requires about 12GB free
• 30B requires about 20GB free

Contributing

Serge is always open for contributions! If you catch a bug or have a feature idea, feel free to open an issue or a PR.

If you want to run Serge in development mode (with hot-module reloading for svelte & autoreload for FastAPI) you can do so like this:

git clone https://github.com/nsarrazin/serge.git
DOCKER_BUILDKIT=1 docker compose -f docker-compose.dev.yml up -d --build

You can test the production image with

DOCKER_BUILDKIT=1 docker compose up -d --build

What's next

• Front-end to interface with the API
• Pass model parameters when creating a chat
• Manager for model files
• Support for other models
• LangChain integration
• User profiles & authentication

And a lot more!
