Three Chinese AI Models Launched in One Month — and the West Should Be Worried

Between July 16 and July 31, three Chinese AI labs shipped frontier-class models inside a single window — a pace no Western lab matched. Adoption is shifting fast: US companies now route over 30% of their OpenRouter tokens through Chinese open-weight models, up from 4.5% in H1 2025. The question isn’t whether Chinese AI models are good enough anymore. Why are US companies switching to Chinese AI models? Chinese open-weight models run 60% to 90% cheaper than flagship models from OpenAI and Anthropic.
