U.S. firms increasingly adopt Chinese open-weight AI models, data shows

New spending data from Ramp indicates a growing share of U.S. businesses are using model-serving platforms that offer open-weight and Chinese-developed AI systems, rising from 4.5% in January to 6.1% in July 2026. These models, such as Moonshot's Kimi K3 and Z.AI's GLM-5.3-Flash, provide cheaper and more customizable alternatives to closed-source U.S. rivals. The trend suggests enterprises are increasingly looking beyond American AI providers for cost and control advantages.
