Grok 4

Previous

The Grok 4 generation model that preceded the 4.3 flagship, with a 256K-token context window. Grok 4.3 supersedes it on both capability and price, so this entry is mainly relevant to workloads already pinned to Grok 4 behaviour.

Grok 4 is a frontier AI model from xAI. It costs $3.000 per million input tokens and $15.000 per million output tokens (blended $6.600/M), with a 256,000-token context window.
