OpenAI Grants EU Commission Access to GPT-5.5-Cyber While Anthropic Withholds Mythos from Brussels
OpenAI announced Monday it will grant the European Commission, EU institutions, and vetted European cybersecurity teams preview access to GPT-5.5-Cyber through a new OpenAI EU Cyber Action Plan. Anthropic has declined to grant similar access for its Mythos model. The EU Commission confirmed 'four or five' meetings with Anthropic but said discussions are 'not yet at the same stage' as with OpenAI.
