## Configuration Options

### Basic Setup (Recommended)

```bash

OPENCLAW_DEFAULT_MODEL=xai/grok-beta
```

### Custom Base URL

```bash
XAI_API_KEY=gsk_xxxxx
XAI_BASE_URL=https://api.x.ai/v1
```

### Multiple Providers

You can use xAI Grok alongside other providers:

```bash
# xAI Grok
XAI_API_KEY=gsk_xxxxx

# OpenRouter (fallback)
OPENROUTER_API_KEY=sk-or-v1-xxxxx

# Local model (free, CPU-only)

OpenClaw will prioritize providers in this order:

2. OpenAI (if `OPENAI_API_KEY` is set)
3. OpenRouter (if `OPENROUTER_API_KEY` is set)
4. Local (if `LOCAL_MODEL_ENABLED=true`)

## Troubleshooting

### "Incorrect API key provided"

- Verify your key starts with `gsk_`
- Make sure there are no spaces or newlines
- Check key is active in https://console.x.ai

### "Model not found"

- Use exact model ID: `grok-beta` (not `Grok-Beta` or `grok_beta`)
- Check model availability in xAI console

### Slow Responses

- Grok Beta is typically very fast (<1s)
- Check your internet connection
- Verify HF Spaces region (closer to xAI servers = faster)

### Rate Limits

- Check your quota in https://console.x.ai
- Consider upgrading your plan if hitting limits
- Use LOCAL_MODEL_ENABLED as fallback for free inference

## Example: WhatsApp Bot with Grok

```bash
# HF Spaces secrets
XAI_API_KEY=gsk_xxxxx
HF_TOKEN=hf_xxxxx
AUTO_CREATE_DATASET=true

# WhatsApp credentials (set in Control UI)
WHATSAPP_PHONE=+1234567890
WHATSAPP_CODE=ABC123
```

Result: Free, always-on WhatsApp AI bot powered by Grok!
