WIRED·

OpenAI released an improved version of its cybersecurity model GPT-5.5-Cyber alongside a 'Patch the Planet' initiative to use AI for identifying and patching bugs in open-source software. The effort is a direct competitive move against Anthropic's Mythos model in the AI-for-security space. The initiative could reshape how open-source maintenance is funded and executed.
Technical significance
If AI-driven patching achieves meaningful scale, it could reduce the maintenance burden on open-source maintainers — a critical bottleneck in software security. However, the quality and safety of AI-generated patches at scale remains an open question.
