Grok 4 (0709)

Retired

Retired from the xAI API on 2026-05-15 12:00 PM PT per official migration page. Requests to this slug now auto-redirect to grok-4.3 with 'low' reasoning effort; the slug still resolves so existing code does not break. Knowledge cutoff Nov 2024 per docs note covering Grok 4. Per-token pricing no longer published on docs (was historically $3/$15 per M per third-party trackers); left null as not officially current.

Lifecycle warning
