Grok 4.6 is the new agent model of the day
Long trajectories, visual first passes, and a week of double usage in Cursor.
Cursor and SpaceXAI released Grok 4.6 for agents that stay on a task across many steps. They pitch it as a jump from 4.5 on turning a vague product idea into a working first version, with more self-testing on long runs. It matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index. Price starts at 2 dollars per million input tokens and 6 per million output. A fast variant costs twice that.
