At an event in Beijing earlier this year, some of China’s top artificial intelligence leaders warned that the country remained meaningfully behind the U.S. in developing cutting-edge AI models, with one executive arguing that “the gap may actually be widening.”
Leading U.S. firms also appeared confident they were significantly ahead. As recently as last week, one executive at Anthropic, who spoke on condition of anonymity, mused that the Claude maker’s technology was roughly six to 12 months ahead of Chinese rivals.
On Friday, Moonshot AI upended those assumptions. The Chinese AI lab released Kimi K3, a more advanced open-weight model that it said outperforms all rivals except for Anthropic’s Claude Fable 5 and OpenAI’s GPT-5.6 on overall capability. The implication is that Moonshot, and by extension China, could be closing the gap faster than expected.
