# HuggingChat (chat-ui)

## What's in the image

This is the `chat-ui-db` variant — same UI as huggingface.co/chat, but with SQLite bundled instead of requiring external MongoDB. Perfect for self-hosting without infrastructure.

## Default models

Out of the box, the UI ships with a few default HuggingFace Inference endpoints (free tier, rate-limited). Set `HF_TOKEN` to use your account quota.

## Custom models (MODELS env)

Set `MODELS` to a JSON array like:

```json
[{
  "name": "meta-llama/Llama-3.1-8B-Instruct",
  "endpoints": [{
    "type": "tgi",
    "url": "https://my-tgi.example.com"
  }]
}]
```

Supported endpoint types: `tgi` (HuggingFace Text Generation Inference), `openai`, `anthropic`, `cohere`, `vertex` (Google), `aws`. See [chat-ui docs](https://github.com/huggingface/chat-ui#configuration).

## Web search

Set `SERPAPI_KEY` (or `SERPER_API_KEY` / `YDC_API_KEY` for You.com) and the UI grows a 'Search' tool — model can browse the web for current info.

## Multi-user

With `OPENID_CONFIG` (point at a OIDC provider) you get accounts + per-user history. Without it, history is anonymous-per-browser-cookie.

## Storage

SQLite at `/data/db.sqlite`. Conversations + user data persist across container restarts. 5 GB volume is enough for years of chat.
