Summary
Grok 4.6 is now live in Cursor, Grok Build, the API, and partners including OpenRouter, Vercel and Cloudflare, with pricing from $2 per million input tokens and $6 per million output tokens.
The model targets long-running agents, coding and visual product work, with xAI saying it can sustain multi-step research, work across codebases and turn broad ideas into working first versions.
On benchmarks, xAI said Grok 4.6 matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index, a composite of 9 tests, and improves on Grok 4.5 in first-pass interactive and visual output.
xAI attributed the gains to a longer training run, regenerated supervised fine-tuning traces, broader agentic reinforcement-learning tasks and expanded safety testing calibrated to the model’s stronger capabilities.
A fast variant costs 2x more, while Grok Build and Cursor users get 2x included usage for the first week as xAI pushes adoption of its latest model.
