xAI released Grok 4.6, its new flagship model, aimed at tasks that run over many steps and at building interactive and visual software. It is available now in Cursor, Grok Build, the company's API and partners including OpenRouter, Vercel and Cloudflare. xAI reports it matches GPT-5.6 Sol on a composite benchmark score, though rival models still lead on several coding tests.

What changed

Grok 4.5 was xAI's most capable model, scoring lower on the same coding and knowledge-work tests.

What it unlocks

Running longer multi-step agent tasks and generating a first working version of a visual or interactive app in one pass.
