# Jan
Jan is a free, source-available and [fair code licensed](https://faircode.io/) AI Inference Platform. We help enterprises, small businesses and hobbyists to self-host AI on their own infrastructure efficiently, to protect their data, lower costs, and put powerful AI capabilities in the hands of users.
## Features
- Web, Mobile and APIs
- LLMs and Generative Art models
- AI Catalog
- Model Installer
- User Management
- Support for Apple Silicon, CPU architectures
## Installation
### Pre-Requisites
- **Supported Operating Systems**: This setup is only tested and supported on Linux, Macbook Docker Desktop (For mac m1, m2 remember to change Docker platform `export DOCKER_DEFAULT_PLATFORM=linux/amd64`), or Windows Subsystem for Linux (WSL) with Docker.
- **Docker**: Make sure you have Docker installed on your machine. You can install Docker by following the instructions [here](https://docs.docker.com/get-docker/).
- **Docker Compose**: Make sure you also have Docker Compose installed. If not, follow the instructions [here](https://docs.docker.com/compose/install/).
- **Clone the Repository**: Make sure to clone the repository containing the `docker-compose.yml` and pull the latest git submodules.
```bash
git clone https://github.com/janhq/jan.git
cd jan
# Pull latest submodule
git submodule update --init --recursive
```
- **Environment Variables**: You will need to set up several environment variables for services such as Keycloak and Postgres. You can place them in `.env` files in the respective folders as shown in the `docker-compose.yml`.
```bash
cp sample.env .env
```
| Service (Docker) | env file |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
| Global env | `.env`, just run `cp sample.env .env` |
| Keycloak | `.env` presented in global env and initiate realm in `conf/keycloak_conf/example-realm.json` |
| Keycloak PostgresDB | `.env` presented in global env |
| jan-inference | `.env` presented in global env |
| app-backend (hasura) | `conf/sample.env_app-backend` refer from [here](https://hasura.io/docs/latest/deployment/graphql-engine-flags/config-examples/) |
| app-backend PostgresDB | `conf/sample.env_app-backend-postgres` |
| web-client | `conf/sample.env_web-client` |
### Docker Compose
Jan offers an [Docker Compose](https://docs.docker.com/compose/) deployment that automates the setup process.
```bash
# Download models
# Runway SD 1.5
wget https://huggingface.co/runwayml/stable-diffusion-v1-5/resolve/main/v1-5-pruned-emaonly.safetensors -P jan-inference/sd/models
# Download LLM
wget https://huggingface.co/TheBloke/Llama-2-7B-Chat-GGML/resolve/main/llama-2-7b-chat.ggmlv3.q4_1.bin -P jan-inference/llm/models
``````
Run the following command to start all the services defined in the `docker-compose.yml`
```shell
# Docker Compose up
docker compose up
```
To run in detached mode:
```shell
# Docker Compose up detached mode
docker compose up -d
```
| Service (Docker) | URL | Credential |
| -------------------- | --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Keycloak | http://localhost:8088 | Admin credentials are set via the environment variables `KEYCLOAK_ADMIN` and `KEYCLOAK_ADMIN_PASSWORD` |
| app-backend (hasura) | http://localhost:8080 | Admin credentials are set via the environment variables `HASURA_GRAPHQL_ADMIN_SECRET` in file `conf/sample.env_app-backend` |
| web-client | http://localhost:3000 | Users are signed up to keycloak, default created user is set via `conf/keycloak_conf/example-realm.json` on keycloak with username: `username`, password: `password` |
| llm service | http://localhost:8000 | |
| sd service | http://localhost:8001 | |
## Usage
To get started with Jan, follow these steps:
1. Install the platform as per the instructions above.
2. Launch the web application via `http://localhost:3000`.
3. Login with default user (username: `username`, password: `password`)
4. Test the llm model with `chatgpt` session
