OpenAI is rolling out the full, limited-release version of GPT-5.5-Cyber—a specialized AI model that outperforms its predecessors and Claude Mythos 5 in security benchmarks like CyberGym.
OpenAI released GPT-5.5-Cyber (85.6% CyberGym vs Claude Mythos 5's 83.8%) with Codex Security validated on 30M+ commits. For enterprises at scale, the bottleneck is patching—agentic reasoning automates vulnerability validation and patch generation, integrating SARIF/CodeQL to compress discovery-to-fix cycles.
