Summary
Patch the Planet is a collaboration between Trail of Bits and OpenAI that uses advanced AI models like GPT-5.5-Cyber to find security bugs in open-source software before attackers can exploit them. In one case, GPT-5.5-Cyber independently built sophisticated fuzzing tools (automated testing systems that find bugs by trying many unexpected inputs) for zlib, a widely-used compression library, discovering new vulnerabilities in just one day without being explicitly instructed how to do so.
