OpenAI unveils GPT-5.5-Cyber update and launches Patch the Planet bug-fixing initiative
Wired reports that OpenAI has introduced an updated cyber-focused model, GPT-5.5-Cyber, and a related initiative called Patch the Planet aimed at helping fix bugs in open-source software. The announcement comes amid heightened attention to the cybersecurity capabilities and risks of advanced AI systems, and is framed in part against Anthropic's cyber-oriented Mythos offering.
Why it matters: This is a notable cyber-safety and product-positioning move from a leading AI lab. A stronger model paired with a concrete software-patching program suggests OpenAI is trying to show beneficial cybersecurity use cases while competing over how high-risk model capabilities should be deployed and governed.
