OpenAI has expanded its Daybreak cybersecurity access programme with two new tiers and a specialist model, GPT-5.6-Cyber, for approved defensive security users.
Daybreak Blue gives authorised users access to OpenAI's general-purpose models, including GPT-5.6 Sol, with safeguards adjusted for defensive cyber work.
GPT-5.6-Cyber is built on GPT-5.6 Sol and trained for specialised cyber tasks, including zero-day vulnerability discovery and exploit-chain development.
That compared with 1.5% for GPT-5.6 Sol and 2.0% for GPT-5.6 Sol when used through Daybreak Blue, according to OpenAI.
Both GPT-5.6 Sol and GPT-5.6-Cyber improved on GPT-5.5-Cyber, but GPT-5.6-Cyber trailed GPT-5.6 Sol because it sometimes produced shorter, less detailed reports.
