The newest Kimi K3 model from Beijing-based startup Moonshot, run by a Pink Floyd-loving entrepreneur who earned his doctorate in Pittsburgh, appears to be catching up to the best versions of Anthropic's Claude and OpenAI's ChatGPT.

Moonshot AI released Kimi K3, a 2.8 trillion-parameter open-source AI model from China that rivals OpenAI, Anthropic and other top U.S. systems in frontier AI benchmarks.

Moonshot's Kimi K3 beat Claude Fable 5 and GPT 5.6 in some benchmarks... and it's an open model.

Moonshot AI's latest model is impressing developers with its coding skills, low API costs, and open-weight strategy.
