OpenAI expands its cybersecurity AI and Google Chrome is now safer

OpenAI has taken another step to its lineup of security tools. With the expansion of Daybreak and the arrival of GPT-5.6-Cyber, the company wants to give the best research tools to the people securing apps and services. And the first result is already impressive: Google Chrome is now safer.

Daybreak Red launches a GPT specialized in cybersecurity

The idea builds on what we already saw with GPT-5.4-Cyber and continues the evolution of GPT-5.6 Sol. Daybreak is split into Blue, meant for more general defensive tasks, and Red, meant for vulnerability research, exploit validation, and product security testing.

According to OpenAI, GPT-5.6-Cyber now completes 95% of the requests in its internal cybersecurity evaluation. Its specialized training helps find zero-day vulnerabilities and building working exploits, especially in tests like ExploitGym.

And Chrome has already benefited from this work

During its tests, OpenAI used GPT-5.6-Cyber to study V8, Chrome’s JavaScript engine. The model found two previously unknown vulnerabilities that could be chained together to corrupt memory and escape the sandbox. With ChatGPT’s report, OpenAI’s security researchers verified the findings and reported them to Google, which has already fixed one of them.

The news is interesting for Chrome security, but more importantly, it shows how powerful these tools are. A very practical use of generative AI to directly improve the software we use every day, and to do it before any flaw can become a threat.
