OpenAI has expanded its cybersecurity initiative Daybreak and introduced a new cyber AI model called GPT 5.6 Cyber. For those unaware, Daybreak was launched earlier this year as a cyber defence service that gives security teams access to AI models, tools and workflows. The upgraded Daybreak service will now be offered through two tiers called Blue and Red. Both tiers will give approved customers access to OpenAI’s limited-access frontier cyber models. Keep reading for the details.
OpenAI has divided Daybreak into two tiers based on the cybersecurity tools and capabilities customers need.
Blue is designed as the “starting option for most defenders,” OpenAI explained in a blogpost. It provides tools for common defensive cybersecurity tasks. These include incident response, malware analysis and patch validation.
Red offers more advanced cybersecurity capabilities. It gives approved users access to “purpose-trained cybersecurity models” that can be used for security testing and vulnerability research.

OpenAI has also introduced GPT 5.6 Cyber as part of the Daybreak expansion. The new cybersecurity-focused model is available only through the Red tier.
GPT 5.6 Cyber is based on GPT 5.6 Sol but has been designed to perform better on specialised cybersecurity tasks. “The GPT 5.6 Cyber model is trained to improve performance on certain cybersecurity workflows involving exploit development and advanced security research,” the company said.
GPT 5.6 Cyber is said to perform better than GPT 5.6 Sol and GPT 5.5 Cyber on ExploitGym. This benchmark tests whether AI agents can take known software vulnerabilities and turn them into working exploits in controlled environments.
OpenAI further explained, “Another area that GPT 5.6 Cyber is aimed to improve is the ability to find and accurately calibrate the severity of novel zero-day vulnerabilities.”
The company also clarified that GPT 5.6 Cyber was not involved in the Hugging Face hacking incident. “Note that as we mentioned in our updates to the Hugging Face incident, GPT 5.6 Cyber was not involved in exploiting Hugging Face, nor are any other models planned for an upcoming release,” OpenAI wrote.
