Kimi K3.1 Pro is available on OpenRouter

How we know

A model that has just appeared on a provider price list.

Every hour we read OpenRouter's public list of models and compare it with the list we saved last time. A model that is new on the list, and was released in the last three weeks, becomes a signal. Its context size, prices and size come straight from the list.

What it does not tell you. OpenRouter lists a model when it becomes available there, which is usually the day the lab releases it but not always. The lab's own announcement is the final word.

Detected Oct 23 from OpenRouter model list (opens in a new tab). How every kind of signal is made.
