Kimi K3.1 Pro and K3.1 Pro Highspeed are out

Moonshot dropped K3.1 Pro and a Highspeed variant, first model of their new line. Top of HN right now. Anyone run it on real coding/agent tasks yet? Curious about the Highspeed tradeoffs vs the full model.

tried it on a messy refactor in a 40k line repo, honestly it held context better than i expected. tool calling is solid

highspeed is noticeably snappier, maybe slightly lazier on long plans
