Significant updates from Kimi, the models built by Chinese lab Moonshot AI, collected from the company's own sources and rewritten as short, explained entries. The log starts at the launch of Kimi K3. Everything is grouped by the date the change was detected, and every entry links to the primary source.
Kimi Code is Moonshot's command line tool, where the model works directly in a code project from the terminal. Version 0.31.0 lets you define your own agents in ordinary markdown files, and plugins can now supply both ready-made agents and instructions for the system prompt. The /secondary_model command sets which model subagents use, though it is experimental and has to be enabled in /experiments first.
Why it matters
A team can package its own way of working into a plugin instead of every developer setting up the same thing again. The fix a day later removes, among other things, a bug where a new session displayed the wrong thinking level while actually running with thinking off.

Version 0.31.0, with fixes in 0.31.1 the following day. Subscription requirements are not specified.
Moonshot AI has published the complete weights for Kimi K3, meaning all the numbers that make up the finished trained model. With them, anyone can download the model and run it on their own hardware rather than going through the company's API. The date matches what the company promised in its launch post, which said the weights would arrive by July 27.
Why it matters
A model of this size that can be run locally is rare, and for organisations whose data cannot leave the building it is the difference between being able to use it and not. Actually running it demands serious hardware, and the licence is Moonshot's own rather than a standard open source one.

Open weights, uploaded July 27, 2026. Released under Moonshot's own Kimi K3 License, not a standard one.
Kimi K3 is Moonshot AI's new flagship model: 2.8 trillion parameters, a 1 million token context window, which is how much text it can hold in mind at once, and built-in understanding of images. The company calls it the world's first open model in the 3-trillion class. Moonshot states itself that overall it still trails Claude Fable 5 and GPT-5.6 Sol. The company's own pricing page lists kimi-k3 at $3 per million input tokens and $15 per million output tokens, with 30 cents for text already held in the cache.
Why it matters
The price sits well below what the leading American models charge, and the model can also be run locally by anyone who wants to. In exchange, the vendor itself concedes it is not as strong, so the choice is between cost and the last stretch of quality.
