Inside OpenAI’s plan to protect the internet before hackers break it

Clint Gibler had only been in charge of OpenAI’s elite hacker lab for a few months when a cybersecurity researcher alerted his team to a shocking discovery. OpenAI’s premier model, GPT-5.6 Sol, had found serious flaws inside PHP, the web programming language that underpins 70% of the websites on the internet today. For more than two months, the AI giant and its collaborators raced behind the scenes to validate the findings and ensure the fixes worked before publicly announcing them this week. A mad scramble ensued to rush out patches across the web as hackers launched millions of attacks to try to exploit the bugs. The PHP flaws are the first major cybersecurity problems discovered using AI.
