EU regulators rely on voluntary access from OpenAI and Anthropic
openai offered eu regulators access to its new model gpt-5.5 cyber, while the commission struggles to secure similar access to anthropic's mythos model.
the european commission confirmed openai offered access to its gpt-5.5 cyber model, welcoming the transparency as a way to oversee deployment and security. commission spokesperson thomas regnier stated that agencies like enisa and the ai office are potential recipients, while discussions with anthropic regarding its mythos model have yet to yield access. this disparity exposes a power imbalance where eu regulators lack legal强制力 to inspect frontier models, relying instead on voluntary corporate compliance. the commission is simultaneously pushing to finalize the cybersecurity act to strengthen its regulatory position.
