It's the latest AI model from China to close the performance gap with leading U.S. AI labs.

Kimi K3 still trails Anthropic’s Claude Fable 5 and OpenAI’s GPT 5.6 Sol on overall performance, the company said on Friday, but consistently outperformed other tested models.

The model beat Claude Opus 4.8 and GPT 5.5 — models that sit just behind Anthropic and OpenAI’s leading-edge systems — on benchmarks including coding and general agents, according to Moonshot.

It’s China’s largest AI model so far, with 2.8 trillion parameters, referring to the size of its neural network.
