What changed

  • Priced $2/$6 per MTok ($4/$12 for every token once a prompt reaches 200K); cached input $0.50, or $1.00 at 200K and above. Context stays at 500K with no published output cap.
  • Shipped the same day on the xAI API, in Cursor, Grok Build and GitHub Copilot; xAI's model docs now tell developers to use Grok 4.7.
  • Scores 46.3% on CursorBench 4.0 (Extra High, $6.01/task) and 46.4 on the Artificial Analysis Intelligence Index v4.3.2 (xhigh).

Best fit

  • Coding agents in Cursor and Copilot
  • xAI API stacks
  • Frontier work at a mid-tier price

What to be careful about

  • 500K context is half the 1M-class frontier rows, and there is no Batch API.
  • The US regional endpoint costs 1.1x, and the 2x-price 'Fast' variant is limited to Cursor and Grok Build.
