Jan - Run your own AI

Getting Started - Docs - Changelog - Bug reports - Discord

⚠️ Jan is currently in Development: Expect breaking changes and bugs!

Jan lets you run AI on your own hardware, with helpful tools to manage models and monitor your hardware performance.

In the background, Jan runs Nitro, a C++ inference engine. It runs various model formats (GGUF/TensorRT) on various hardware (Mac M1/M2/Intel, Windows, Linux, and datacenter-grade Nvidia GPUs) with optional GPU acceleration.

See the Nitro codebase at https://nitro.jan.ai.

For interactive development

Note: This instruction is tested on MacOS only.

1. Clone the Repository:

   git clone https://github.com/janhq/jan
   git checkout feature/hackathon-refactor-jan-into-electron-app
   cd jan
   

2. Install dependencies:

   yarn install
   
   # Packing base plugins
   yarn build:plugins
   

3. Run development and Using Jan Desktop

   yarn dev
   

   This will start the development server and open the desktop app. In this step, there are a few notification about installing base plugin, just click OK and Next to continue.

For production build

# Do step 1 and 2 in previous section
git clone https://github.com/janhq/jan
cd jan
yarn install
yarn build:plugins

# Build the app
yarn build

This will build the app MacOS m1/m2 for production (with code signing already done) and put the result in dist folder.
