xAI retires older Grok models, requests redirect to Grok 4.3
On May 15, 2026 xAI retired grok-4-1-fast, grok-4-fast, grok-4-0709, grok-code-fast-1, grok-3 and grok-imagine-image-pro. Requests to these slugs redirect to grok-4.3 (or grok-build-0.1 for grok-code-fast-1) and are billed at grok-4.3 rates of $1.25 input and $2.50 output per 1M tokens.
After
grok-4.3 at $1.25 / $2.50 per 1M tokens
- Action needed:
- Set the model explicitly to grok-4.3 with the reasoning effort you want, or grok-build-0.1 for coding.
