Note: xAI retired the grok-3 API model slug on 2026-05-15 as part of the Grok 4.3 rollout (docs.x.ai/developers/migration/may-15-retirement). Requests to grok-3 now redirect to Grok 4.3. The current model table at docs.x.ai/docs/models lists only grok-4.x variants, no grok-3. Entry left unchanged per PR #59 precedent; current xAI flagship is Grok 4.6.
