OpenAI announced a flurry of cybersecurity-related AI news on Monday, releasing an improved version of GPT‑5.5‑Cyber, its most advanced vulnerability-finding model, along with an expanded partner program for cybersecurity vendors, an update to its Codex Security scanner, and an initiative to “Patch the Planet” – or at least 30 high-profile open source projects.
The announcements come as Anthropic’s Mythos mess keeps getting more complicated, with national security concerns clouding defenders’ abilities to use that AI company’s most advanced models to find and fix vulnerabilities – or perhaps it’s just politics as usual.
They also coincide with a general feeling of FUD around AI cyberattacks and the impending vulnpocalype. The Reg’s vultures will keep out collective eyes on all of this.
First off: GPT‑5.5‑Cyber. After releasing a preview version of the model to a select group of “trusted defenders,” OpenAI on Monday released an update that it says makes the model even better at finding – and also fixing – bugs in code.
“It is our strongest model yet for finding and helping patch software vulnerabilities, while retaining GPT‑5.5’s general-purpose intelligence and ability to work across long, complex tasks,” the AI shop said. “The model can sustain deeper analysis across large codebases: identifying security-relevant components, tracing whether vulnerable code is reachable, validating likely issues in controlled environments, developing and testing patches, and preparing evidence for human review.”
OpenAI said it evaluated the update and 5.5 preview using a few different benchmarks: CyberGym, which test how well AI systems can reproduce known vulnerabilities; ExploitGym, which determines how well models can turn known vulnerabilities into working exploits that achieve unauthorized code execution; and SEC-bench Pro, which measures AI systems’ long-horizon vulnerability discovery and proof-of-concept…
