🚀 **`grok-4.7` is live, on a new 2.1T base model at the same price as Grok 4.6**

SpaceXAI released it on September 21. Parameters grow from 1.5T to 2.1T, and reinforcement learning puts more weight on multi-hour tasks. In independent testing, Terminal-Bench 4.0 rises from 18% to 33%, with the biggest gains in coding agents.

* Pricing: \$2 / \$6 per million tokens, \$0.50 for cached reads, second tier above 200K, matching the provider
* Groups: `default` / `svip` / `CodexResponses`
* Context: 500K, with text and image input

Note: the unit price is unchanged, but it uses about twice the output tokens per task as Grok 4.6, so compare a bill on real tasks before switching. Full write-up: [Grok 4.7 Is Live](/en/news/grok-4-7-launch).
