OpenAI Drops GPT-5.5-Cyber Update, Teams Up to Squash Open Source Bugs
OpenAI upgrades its cybersecurity-focused model and launches Patch the Planet with Trail of Bits to fix open source vulnerabilities.
OpenAI just pulled the wraps off an upgraded GPT-5.5-Cyber model — its AI built specifically for cybersecurity work. The company also announced "Patch the Planet," a new initiative with security firm Trail of Bits aimed at hunting down and fixing bugs in open source software.
The moves come as the industry wrestles with growing anxiety over what AI models can actually do in the cybersecurity space. Rather than just talking about responsible AI, OpenAI is betting on direct action — pointing its models at the massive backlog of vulnerabilities lurking in open source codebases that underpin most of the internet.
Trail of Bits brings serious security chops to the partnership. The firm is well-known for auditing smart contracts and critical infrastructure code. Pairing their expertise with OpenAI's beefed-up cyber model could meaningfully accelerate the pace of vulnerability discovery and patching across widely used projects.
