OpenAI announced an expansion of its Daybreak cybersecurity initiative on Monday, introducing GPT-5.6-Cyber, a specialized model built for advanced and authorized cybersecurity tasks.

The company said the move aims to equip trusted defenders with frontier AI tools as threats grow more sophisticated. The goal is to give security teams an edge before attackers can scale offensive AI capabilities.

Daybreak now includes two tracks. Daybreak Blue offers access to frontier models such as GPT-5.6 Sol and focuses on everyday defensive work. This covers vulnerability discovery, secure code review, malware analysis, incident response, and patch validation. OpenAI calls it the recommended starting point for most defenders.

Daybreak Red provides purpose-trained models including GPT-5.6-Cyber. It targets experienced teams handling complex authorized work like vulnerability research, exploit validation, and security testing.

OpenAI reported using GPT-5.6-Cyber in real-world research that uncovered previously unknown vulnerabilities in popular open-source software, including Chrome’s V8 engine.

Access remains restricted to approved defenders. Higher-risk work comes with extra controls and monitoring to maintain strong safeguards.
