OpenAI expands Daybreak with a higher-access tier for its cybersecurity model
Materially updated August 11, 2026
OpenAI has added a second, higher tier to its Daybreak cybersecurity program that gives approved partners access to a more capable cyber model. Engadget reports the model is less likely to refuse higher-risk tasks, indicating a meaningful change in how OpenAI is packaging and controlling advanced defensive cyber capabilities.
Why it matters: This is a substantive follow-on to OpenAI’s controlled cybersecurity rollout because it changes access levels, not just messaging. A leading lab is refining how stronger dual-use cyber models are gated for selected defenders, which has implications for security operations, competitive positioning, and AI safety governance.
What changed
- OpenAI gives Daybreak partners access to a more powerful cybersecurity model
- As AI-led attacks multiply, OpenAI launches a new cyber model
- OpenAI launches GPT-5.6-Cyber with reduced refusals, 95% completion on advanced cybersecurity tasks
