China’s open-source artificial intelligence models accounted for nearly 30 per cent of total global use of the technology, while Chinese-language prompts ranked second in token volume behind English, according to a report.
Proprietary Western models, such as OpenAI’s GPT-4o and GPT-5, remained dominant with a 70 per cent global share.
According to the empirical study of 100 trillion tokens by OpenRouter, Chinese open-source LLMs’ global share started from a low base of 1.2 per cent in late 2024 to reach nearly 30 per cent over a few months this year. Tokens are units of data processed by AI models during training and inference, enabling prediction, generation and reasoning.
So far this year, Chinese open-source LLMs averaged 13 per cent of weekly token volume, as growth accelerated in the second half of 2025, to almost match the 13.7 per cent average recorded by AI models from the rest of the world, the report said.
“China has emerged as a major force, not only through domestic consumption but also by producing globally competitive models,” the report said.
