Chinese startup Moonshot will launch Kimi K3 in the coming days. The model contains between 2 and 3 trillion parameters. This scale represents a significant increase for Chinese AI development.
Kimi K3 reportedly outperforms Anthropic’s Claude Opus 4.8 on key benchmarks. The performance signals a narrowing gap between Chinese and U.S. frontier AI. Moonshot will release Kimi K3 as an open-weight model for free download and modification. This strategy challenges the closed-source business models of OpenAI and Anthropic.
