Grok 4.6 is the current SpaceXAI frontier API row in this catalog, with a 500K context window and published $2/$6 per-million-token rates.
What changed
- xAI announced Grok 4.6 GA on 2026-08-12.
- This catalog lists it separately from Grok 4.5.
- CursorBench Extra High led the mirrored 3.2 board in the 2026-08-14 snapshot.
Best fit

- SpaceXAI API stacks
- Long-context agent work
What to be careful about
- Confirm live xAI list rates before volume commits.
- CursorBench is an IDE-specific board, not a general API ranking.
