    overview

    xAI's API serves the Grok family — flagship grok-4.6 with 500K context at $2.00/$6.00 per 1M and configurable reasoning — plus Voice (agent/TTS/STT) and Imagine image/video generation, all in an OpenAI-compatible shape. X Search and Web Search are first-party server-side tools; free credits are promotional, not a published standing program.

    free quota

    No standing free-credit program published in xAI's docs (checked 2026-09-16). Promotional credits vary by account/region/campaign — confirm in the console at sign-up.
