Kimi K3.1 is announced as 3.1 Pro. The benchmark scores look to be clearly the strongest current open weight model, if the weights are released as they claim by November 4th. They are very impressive scores.

The Kimi team makes very clear statements about cyber risks and trying to pace the frontier of open-weight cyber capabilities and moderate it with respect to the closed frontier.

Much to be learned in how the model stands up the vibe tests, but in the last few years the Moonshot team has rarely missed with the kimi models. K3.1 is also cheaper than K3 per token, but some benchmarks in the blog show it uses meaningfully more tokens per answer, so it may be about the same price.

This, with all the cyber news, and rumors of a bigger GLM model coming soon, sets us up for an exciting rest of the year! The pro name makes me think Kimi will be moving to release flash model soon too, similar to DeepSeek and GLM.
