    We asked GPT 5.6-Cyber to escape a VM used to sandbox agents. It broke out three times. In its final escape, the agent found three 0-days on its own and chained them into a working exploit. blog.trailofbits.com/2026/08/26/vms…

    Patch the Planet is our joint initiative with @OpenAI to help maintainers strengthen critical open-source software. In one week, we used Codex and GPT-5.5-Cyber to find hundreds of bugs inside OSS like cURL, Python, and the Go project. 37 patches merged, with more in flight. 🧵
