A Chinese startup has launched the world’s largest publicly available AI model (dispelling ideas that they lag far behind the U.S.), as data attributes almost 60% of U.S. firms’ AI usage to cheaper services from China.

Chinese AI startup Moonshot has launched Kimi K3, a 2.8 trillion-parameter model it says is the world’s largest “open-weight” AI system (meaning publicly available for download), with performance approaching Anthropic’s Fable model.
Chinese large language models are rapidly gaining traction with businesses around the world thanks to their lower costs. On AI marketplace OpenRouter, adoption by U.S. firms has climbed to almost 60% and continues to rise.
The latest generation of Chinese models is challenging the long-held view that the country’s AI technology lags the United States by at least six months.
