OpenAI is introducing a more cyber-permissive version of GPT-5.6 Sol to vetted defenders as it prepares companies for autonomous cyberattacks. The move comes just days after OpenAI said it was delaying the release of its forthcoming model, Astra, after it reached critical hacking abilities during safety testing. OpenAI is unveiling GPT-5.6-Cyber while also expanding Daybreak, its program that gives cybersecurity defenders access to the company’s cyber models and other tools. Many cyber defenders have been experiencing high refusal rates across frontier AI models as the labs try to balance giving defenders the tools they need while not accidentally leaking those abilities to malicious hackers. Under the new program, Daybreak will have two tiers: Daybreak Blue, which includes access to GPT-5.6 Sol without its system-level cyber guardrails; and Daybreak Red, which offers access to GPT-5.6-Cyber to validate exploits and do more advanced vulnerability research.
