LocalAI

tests build container images

LocalAI is a drop-in replacement REST API that’s compatible with OpenAI API specifications for local inferencing. It allows you to run LLMs (and not only) locally or on-prem with consumer grade hardware, supporting multiple model families that are compatible with the ggml format. Does not require GPU.

For a list of the supported model families, please see the model compatibility table.

In a nutshell:

  • Local, OpenAI drop-in alternative REST API. You own your data.
  • NO GPU required. NO Internet access is required either. Optional, GPU Acceleration is available in llama.cpp-compatible LLMs. See building instructions.
  • Supports multiple models, Audio transcription, Text generation with GPTs, Image generation with stable diffusion (experimental)
  • Once loaded the first time, it keep models loaded in memory for faster inference
  • Doesn't shell-out, but uses C++ bindings for a faster inference and better performance.

LocalAI was created by Ettore Di Giacinto and is a community-driven project, focused on making the AI accessible to anyone. Any contribution, feedback and PR is welcome!

Usage

Check out the Getting started section. Here below you will find generic, quick instructions to get ready and use LocalAI.

The easiest way to run LocalAI is by using docker-compose (to build locally, see building LocalAI):

git clone https://github.com/go-skynet/LocalAI

cd LocalAI

# (optional) Checkout a specific LocalAI tag
# git checkout -b build <TAG>

# copy your models to models/
cp your-model.bin models/

# (optional) Edit the .env file to set things like context size and threads
# vim .env

# start with docker-compose
docker-compose up -d --pull always
# or you can build the images with:
# docker-compose up -d --build

# Now API is accessible at localhost:8080
curl http://localhost:8080/v1/models
# {"object":"list","data":[{"id":"your-model.bin","object":"model"}]}

curl http://localhost:8080/v1/completions -H "Content-Type: application/json" -d '{
     "model": "your-model.bin",            
     "prompt": "A long time ago in a galaxy far, far away",
     "temperature": 0.7
   }'

Example: Use GPT4ALL-J model

# Clone LocalAI
git clone https://github.com/go-skynet/LocalAI

cd LocalAI

# (optional) Checkout a specific LocalAI tag
# git checkout -b build <TAG>

# Download gpt4all-j to models/
wget https://gpt4all.io/models/ggml-gpt4all-j.bin -O models/ggml-gpt4all-j

# Use a template from the examples
cp -rf prompt-templates/ggml-gpt4all-j.tmpl models/

# (optional) Edit the .env file to set things like context size and threads
# vim .env

# start with docker-compose
docker-compose up -d --pull always
# or you can build the images with:
# docker-compose up -d --build
# Now API is accessible at localhost:8080
curl http://localhost:8080/v1/models
# {"object":"list","data":[{"id":"ggml-gpt4all-j","object":"model"}]}

curl http://localhost:8080/v1/chat/completions -H "Content-Type: application/json" -d '{
     "model": "ggml-gpt4all-j",
     "messages": [{"role": "user", "content": "How are you?"}],
     "temperature": 0.9 
   }'

# {"model":"ggml-gpt4all-j","choices":[{"message":{"role":"assistant","content":"I'm doing well, thanks. How about you?"}}]}

Build locally

In order to build the LocalAI container image locally you can use docker:

# build the image
docker build -t localai .
docker run localai

Or you can build the binary with make:

make build

See the build section in our documentation for detailed instructions.

Run LocalAI in Kubernetes

LocalAI can be installed inside Kubernetes with helm. See installation instructions.

Supported API endpoints

See the list of the supported API endpoints and how to configure image generation and audio transcription.

Frequently asked questions

See the FAQ section for a list of common questions.

Short-term roadmap

  • Mimic OpenAI API (mudler#10)
  • Binary releases (mudler#6)
  • Upstream our golang bindings to llama.cpp (ggerganov/llama.cpp#351)
  • Upstream gpt4all bindings
  • Multi-model support
  • Have a webUI!
  • Allow configuration of defaults for models.
  • Support for embeddings
  • Support for audio transcription with https://github.com/ggerganov/whisper.cpp
  • GPU/CUDA support ( mudler#69 )
  • Enable automatic downloading of models from a curated gallery, with only free-licensed models, directly from the webui.
