Editorial note

Grok 4.6 is xAI's August 2026 update to Grok 4.5, aimed at long-running agent work such as multi-step research and coding across a codebase. xAI reports it tying GPT-5.6 Sol at 61 on the Artificial Analysis Intelligence Index, one point behind Fable 5 (Max) at 62, and sells API access on usage-based token pricing, with a fast variant at twice the standard rate. For teams already on Cursor, OpenRouter, Vercel or Cloudflare it is easy to trial; the benchmark comparison is xAI's own launch chart, so it should be checked on your own workload before switching.
