How China's Open-Source AI is Winning Over U.S. Businesses

China's open-source AI models are increasingly gaining traction among U.S. businesses. Models like Moonshot AI's Kimi K3 and Z.AI's GLM-5.3-Flash are offering more affordable and customizable alternatives to Anthropic and OpenAI's closed-source models.

The Rise of China's Open-Source AI Models

China's open-source AI models have been gaining significant ground. According to Hugging Face, in almost every month of 2026, the largest and most capable open model came from a Chinese lab. Moonshot AI's Kimi K3 model has shown impressive performance in coding and agentic tasks, rivaling leading proprietary systems.

Shift in U.S. Businesses' Preferences

U.S. businesses are starting to favor open-source models over traditional closed-source ones. The Ramp AI Index reported that the share of businesses paying for model serving platforms rose to 6.1% in July 2026, up from 4.5% in January 2026.
