How we got this

Moonshot AI is the maker of Kimi K3. We look at the gaps between its earlier versions (Kimi K2.5, 2026-01-27; Kimi K2.6, 2026-04-20; Kimi K3, 2026-07-16) and project the next one. It is a guess from a pattern, not news: the maker has not said Kimi K3.1 exists. This page turns into the launch page, with price and facts, as soon as the model shows up on OpenRouter, Hugging Face or GitHub.
