New OpenAI Models Likely Pose 'High' Cybersecurity Risk, Company Says

An anonymous reader quotes a report from Axios: OpenAI says the cyber capabilities of its frontier AI models are accelerating and warns Wednesday that upcoming models are likely to pose a 'high' risk, according to a report shared first with Axios. The models' growing capabilities could significantly expand the number of people able to carry out cyberattacks. OpenAI said it has already seen a significant increase in capabilities in recent releases, particularly as models are able to operate longer autonomously, paving the way for brute force attacks.

The company notes that GPT-5 scored a 27% on a capture-the-flag exercise in August, GPT-5.1-Codex-Max was able to score 76% last month. 'We expect that upcoming AI models will continue on this trajectory,' the company says in the report. 'In preparation, we are planning and evaluating as though each new model could reach 'high' levels of cybersecurity capability as measured by our Preparedness Framework.' 'High' is the second-highest level, below the 'critical' level at which models are unsafe to be released publicly. 'What I would explicitly call out as the forcing function for this is the model's ability to work for extended periods of time,' said OpenAI's Fouad Matin.
