xAI releases Grok 4.6 for long-running agents
Grok 4.6 is aimed at work that lasts many steps: research, code, and finished artifacts. It is in the API and partner catalogs, starting at $2 per million input tokens and $6 output. The first week included 2× usage in Cursor and Grok Build.
Grok 4.6 builds on Grok 4.5 with a particular focus on long-running agents.
