## Setup

### LLM Provider Options

The chatbot supports multiple LLM providers (auto-detected based on available API keys):

| Provider | Env Variable | Cost | Notes |
|----------|--------------|------|-------|
| **HuggingFace** | `HF_TOKEN` | Free tier available | Recommended for HF Spaces |
| DeepSeek | `DEEPSEEK_API_KEY` | Pay-per-use | Higher quality |
| Fallback | None needed | Free | Rule-based, limited |

#### Recommended HuggingFace Models (free tier)

```python
# In chatbot.py, change DEFAULT_HF_MODEL to any of these:
"Qwen/Qwen2-1.5B-Instruct"             # Smallest, fastest
"microsoft/Phi-3-mini-4k-instruct"     # Small, good quality
"HuggingFaceH4/zephyr-7b-beta"         # Default, best quality
"mistralai/Mistral-7B-Instruct-v0.2"   # Popular alternative
```

### Environment Variables

**Option 1: HuggingFace (Recommended for HF Spaces)**
```bash
export HF_TOKEN="hf_your_token_here"
```
Get your token at: https://huggingface.co/settings/tokens

**Option 2: DeepSeek**
```bash
export DEEPSEEK_API_KEY="your-api-key-here"
```

### Local Development

python app.py
```

### Hugging Face Spaces

1. Create a new Space with Gradio SDK
2. Upload all files
3. Add `HF_TOKEN` as a secret in Space settings (Settings → Repository secrets)
   - Your HF token works automatically in Spaces
