OpenAI opens the Daybreak cybersecurity tool to the Ukrainian government

OpenAI announced that it is opening its AI vulnerability detection tool Daybreak to Ukraine's Ministry of Digital Transformation to locate and fix software vulnerabilities before they are discovered by Russian hackers. The news was announced on Wednesday during the United Nations General Assembly by Dmytro Kushneruk, Ukraine's Consul General in San Francisco, and Sasha Baker, OpenAI's National Security Policy Lead.

Daybreak is based on OpenAI's flagship large model GPT-5.6 Sol and can scan outdated systems for weaknesses, verify whether suspected vulnerabilities can be exploited, and confirm whether patches actually close the vulnerabilities before they are released. OpenAI has previously opened the model to cybersecurity agencies in France, Germany, and Poland, where Poland's CERT Polska discovered six vulnerabilities in commercial router software, all of which have been fixed by the vendors.

Ukraine's CERT-UA handled nearly 6,000 cyberattacks in 2025, a 37% increase from 2024, with local governments and government agencies being the hardest hit. This opening follows OpenAI's commitment to a $1 billion subsidy program announced on September 3, which is said to expand to "partner countries" in the coming weeks. Jamie MacColl, a researcher at the Royal United Services Institute, told the BBC that Western companies can also gain valuable intelligence from active conflict zones.
