OpenAI limits GPT-5.5-Cyber to 'critical cyber defenders' only
Summary

OpenAI announced GPT-5.5-Cyber, a new frontier cybersecurity model that will not be available to the general public. CEO Sam Altman said the model will first roll out to a select group of critical cyber defenders.

Our take

First major foundation model vendor to implement use-case restrictions rather than just payment tiers. Single source — verify before acting.
