OpenAI restricts GPT-5.5-Cyber launch to trusted cybersecurity professionals only
By
Robert Hart
Crisped on the outside, thoughtful enough on the inside.
Summary
OpenAI is launching GPT-5.5-Cyber, a new cybersecurity-focused AI model that will not be available to the general public. Instead, CEO Sam Altman announced it will be rolled out to a select group of trusted "cyber defenders" and vetted professionals to help institutions strengthen their cyberdefenses. The limited rollout is expected within days, with OpenAI planning to work with the government and ecosystem partners to determine trusted access. This follows a pattern similar to Anthropic's Mythos model, which also restricted initial access to trusted entities.
