Today we are releasing Grok 4.6. Grok 4.6 builds on Grok 4.5 with a particular focus on long-running agents and more ambitious interactive and visual work. It stays with complex tasks across many steps, whether researching a topic, analyzing information, working across a codebase, or turning an idea into a polished application or work artifact. Grok 4.6 achieves frontier intelligence across several agentic coding and knowledge work benchmarks. It matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index, which is a composite score of nine benchmarks.

Notes: Per Elon Musk, this is a 1.5T parameter model, presumably meaning total parameters. Grok 4.6 is almost certainly a sparse mixture of experts model with much fewer active parameters than total. https://x.com/elonmusk/status/2082123925283041545?s=20
