Study Finds China's Open-Weight AI Models Gain Global Users but Revenue Flows to Third-Party Hosts

A new study reports that China's open-weight artificial intelligence models are winning users worldwide, yet much of the revenue they generate is captured by third-party providers rather than the labs that developed them. The research highlights how the open-weight approach has driven rapid adoption while exposing developers to intense competition from platforms that host the models on their own infrastructure and sell access at lower prices. In contrast, United States companies such as OpenAI and Anthropic keep their models closed, retaining tight control over access and pricing. The findings underscore the difficulty Chinese AI labs face in converting widespread adoption into sustainable revenue, even as their models spread globally. The study points to a structural tension in the open-weight ecosystem: the very openness that fuels international uptake also makes it easier for rival hosting platforms to compete on price and capture value. No specific labs, hosting platforms, or financial figures were named in the source material.
