China’s Moonshot AI Releases Model to Challenge Top U.S. Systems

Moonshot AI released Kimi K3, a model it says outperforms some U.S. systems.

Kimi K3 is the world’s largest open-source model with 2.8 trillion parameters.

Moonshot plans to fully open-source Kimi K3 by late July 2026.

Kimi K3 beats Anthropic’s Opus 4.8 and OpenAI’s GPT 5.5 in coding and agent benchmarks.

The release signals Chinese AI labs are closing the gap with U.S. rivals.
