Three EU officials confirmed that the European Union Agency for Cybersecurity (ENISA) and the European Commission's Joint Research Centre (JRC) have begun testing open-weight AI models from China — the first public acknowledgment by either body. The JRC has folded the Chinese models into a broader comparative study covering leading US and European models, examining capabilities, performance, limitations and risks, while ENISA is testing 'a couple' of Chinese open-weight models and has already obtained access to leading Anthropic, OpenAI and Google models. Commission spokesperson Maciej Berestecki said no exclusive access or licensing deals were negotiated with Chinese developers, the models run on the centre's own safeguarded servers, and the Commission does not intend to use them for its own work.
