```yaml
model_list:
    - model_name: xai/*
      litellm_params:
        model: xai/*
        api_key: os.environ/XAI_API_KEY

litellm_settings:
    check_provider_endpoint: true # 👈 Enable checking provider endpoint for wildcard models
```

**2. Start proxy**

```bash
litellm --config /path/to/config.yaml

# RUNNING on http://0.0.0.0:4000
```
