OpenAI Grants EU Access to GPT-5.5-Cyber as Anthropic Still Withholds Mythos

OpenAI said it will give the EU, governments, businesses and cyber authorities access to GPT-5.5-Cyber, rolling the model out in limited preview to vetted cybersecurity teams.
The European Commission said the access will let it track deployment closely and address security concerns, with further talks scheduled this week after an initial exchange with OpenAI.
Anthropic, whose Mythos model was released a month ago and stirred fears of cyberattacks on critical software, still has not granted the EU preview access.
Commission spokesperson Thomas Regnier said Brussels has held four or five meetings with Anthropic, but those talks remain behind the stage reached with OpenAI.
OpenAI framed the move as part of an EU Cyber Action Plan to widen defensive AI access in Europe rather than leave cyber-safety judgments solely to AI labs.
