The next phase of AI cybersecurity still needs humans

Anthropic and OpenAI's cyber-capable AI models may still require significant human expertise to operate effectively, according to new findings from users testing the systems in real-world environments. Why it matters: The new phase of AI-powered cybersecurity may depend less on fully autonomous hacking and more on how effectively humans can direct, validate and operationalize increasingly powerful systems. The big picture: When Anthropic unveiled Mythos Preview to the world, it warned that the model was so powerful that it found tens of thousands of bugs spanning nearly every operating system. Third-party testing suggests that OpenAI's GPT-5.5-Cyber is just as powerful as Mythos at finding bugs and writing exploits. Major companies and governments around the world have been clamoring to get their hands on these models to understand what they'll be up against once similar capabilities fall into the hands of attackers. Driving the news: Several early adopters of Mythos and GPT-5.5 have s
