  modelOptions: {
    // Reasoning
    reasoning_format: 'parsed', // 'hidden' | 'raw' | 'parsed' (mutually exclusive with include_reasoning)
    include_reasoning: true, // mutually exclusive with reasoning_format
    // Response format

## Gotchas

- `chat({ reasoning })` sends `reasoning_effort`. openai/gpt-oss and
  qwen/qwen3.8-27b models take `low`, `medium`, and `high`. qwen/qwen3.8-27b also
  takes `off` (sends `'none'`).
- `include_reasoning` and `reasoning_format` are mutually exclusive.
- Most models have `max_completion_tokens` of 8K-65K, not unlimited.
- Groq specializes in inference speed; model selection is more limited
  than other providers.
- Guard models (`gpt-oss-safeguard-20b`, `llama-prompt-guard-2-*`) are for
  content moderation, not general chat.
