What to do:

Update to 2026.9.35 to use Kimi K3.1 Pro controls.

Moonshot released Kimi K3.1 Pro, a post-trained version of Kimi K3 with a 1-million-token context window, plus a Highspeed variant with 2-3x the speed. Both are available on Kimi.com, Kimi Work, Kimi Code and the Kimi API, and full open weights are due by Nov 4, 2026.

Who is affected:
