Elon Musk announced the launch of Grok 4.6, a new flagship model emphasizing intelligence, speed, and cost-effectiveness. It offers significantly optimized performance at the same price point, with overall capabilities rivaling GPT-5.6 and Claude Fable 5 Max.

Grok 4.6 is now available on Cursor, Grok Build, and other platforms like OpenRouter, featuring a 2x usage bonus in the first week. Pricing is set at $2 per million input tokens and $6 per million output tokens. It scored 1618 on the CodeArena WebDev benchmark.

The model underwent extended training using filtered synthetic data and regenerated SFT trajectories from Grok 4.5. It excels at multi-step complex tasks, effectively turning broad product concepts into runnable applications, and demonstrates emerging self-testing and verification behaviors.
