Chinese start-up Moonshot AI’s Kimi K3 has narrowed the country’s artificial intelligence gap with the US to “a matter of weeks”, fuelling jitters in Silicon Valley over its lead in frontier AI as China doubles down on its open-source strategy.
The Beijing-based unicorn released the Kimi K3, a massive 2.8 trillion-parameter large language model, late last week. According to the company, the model featured native vision capabilities and was built for long-horizon coding, knowledge work and complex reasoning tasks
Larger than any recent flagship model launched by domestic rivals like Zhipu AI and DeepSeek, Kimi K3 outperformed premier closed-source US models – including Anthropic’s Claude Opus 4.8 and OpenAI’s GPT-5.5 – trailing only the most recently released Claude Fable 5 and GPT-5.6 Sol, according to Artificial Analysis.
The model’s performance has toppled the “conventional wisdom” that the best Chinese models lag six to eight months behind their American counterparts, Ryan Fedasiuk, a fellow at the American Enterprise Institute, wrote on Saturday in a report titled “China has caught up in frontier AI”
“That gap has now closed to something approaching a matter of weeks,” Fedasiuk said
While surpassing GPT-5.6 Sol and Claude Fable 5 on certain benchmarks – such as Arena AI’s ranking for front-end code development – Kimi K3 remains significantly cheaper than its US alternatives, despite being pricier than other Chinese models
