xAI (now posting as @SpaceXAI) launched Grok 4.6: a step up from Grok 4.5 at the same price, faster, and built for harder long-running agent, coding, knowledge, and visual work. Pricing is $2/M input and $6/M output—about half other frontier models. It shipped the same day in Grok Build, Cursor, Grok Bot, and the API, with 2x usage in Cursor and Grok Build for the first week. Amazon Bedrock and Pi followed.

Key Takeaways

  • ✓Grok 4.6 is positioned as a long-running agent/coding model and is native in Cursor and Grok Build on day one.
  • ✓At $2/$6 per million tokens it undercuts typical frontier coding prices by about half—material for high-step agents.
