## Hermes Config

```yaml
providers:
  - name: closerouter
    api_key: [REDACTED]
    provider: openai
    base_url: https://api.closerouter.dev/v1
    discover_models: true
```

Models must use prefix format: `openai/gpt-5.4`, `anthropic/claude-opus-4.8`, `deepseek/deepseek-v4-pro`.

## Quirks

- `temperature` parameter is deprecated for Anthropic models — omit it
- Some models (DeepSeek, GLM, Kimi) return empty responses with low max_tokens
- Qwen 3.7 Max was NOT found (404 model_not_found)
- Model names are case-sensitive
- No streaming support confirmed
