# Grok 4.1 (xAI) Support

Status: experimental (November 21, 2025) Owner: Oracle CLI

- Model key: `grok-4.1` (mapped to API id `grok-4-1-fast-reasoning`). Alias: `grok`.
- Endpoint: defaults to `https://api.x.ai/v1` or `XAI_BASE_URL`. Uses the OpenAI Responses API surface.
- Auth: `XAI_API_KEY`.
- Background runs: not supported by the Grok API (requests with `background: true` are rejected). Oracle forces foreground streaming even if `--background` is set.
- Search tools: Grok expects `web_search`; OpenAI’s `web_search_preview` is not accepted.
- Pricing (preview): $0.20 / 1M input tokens, $0.50 / 1M output tokens; 2M token context.

Notes:

- If you supply `--base-url`, it overrides the default xAI endpoint.
- Browser engine is not supported for Grok; Oracle coerces `--engine browser` to `api`.
