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.
