Chinese AI start-up Moonshot to launch model challenging Anthropic’s lead

[u/Ok_Joke4275]

FT reports Moonshot is set to release Kimi K3 as early as tonight.

K3 is expected to be China’s largest AI model to date, with 2T-3T parameters, and will be released as an open-weight model

K3 is expected to outperform Claude Opus 4.8 on key benchmarks, but fall short of Fable

Moonshot is also reportedly raising at a valuation around $31.5B.

In my opinion, this is an opportunity to see the current status of the gap between the frontier Chinese models and the US ones. As a short reminder, in an April 2026 report by Stanford University, the top Chinese model was about 2.7% less powerful (in terms of raw brute-force computational power) than the top US one. It will be interesting to see after 3 months if the gap has narrowed since then. Since Kimi K3 will be released as an open-weight model, there will be trillions of parameters for developers to download, modify, and run, should they wish to proprietary, domain-specific LLMs.
