# OpenAI Has a New GPT-5.4-Cyber Model. OpenAI has a new AI model called GPT 5.4-Cyber, but it’s not coming to your ChatGPT. OpenAI uses the feedback from these testers for “understanding the differentiated benefits and risks of specific models, improving resilience to jailbreaks and other adversarial attacks, and improving defensive capabilities — while mitigating harms,” the company said. The model release is part of a ramped-up version of OpenAI’s Trusted Access for Cyber program, which allows verified cybersecurity professionals and organizations to get early access to models for defense and prevention work. Anthropic’s next-generation model, Claude Mythos Preview, is apparently so powerful that the company says it has already found security vulnerabilities “in every major operating system and web browser,” according to a blog post”). Unlike Claude Mythos Preview, which Anthropic said is an entirely new model, OpenAI’s GPT-5.4-Cyber is a fine-tuned version of its existing GPT-5.4 large language model.
