OpenAI announced that it will provide the government of Ukraine with the Daybreak AI-based cyber defense system for free. The system is intended to help protect civilian infrastructure, including hospitals and power plants, from cyberattacks, and through it Kyiv will gain access to the GPT 5.6 Sol version for cyber defense.
This model has been publicly available since July, but in Daybreak its restrictions have been loosened so specialists can search for vulnerabilities and repel attacks. Daybreak can also quickly find vulnerabilities in digital systems and help develop fixes.
According to the national cyber incident response team CERT-UA, Ukraine recorded nearly 6,000 cyberattacks in 2025. OpenAI announced the deal in parallel with the UN General Assembly, which is currently taking place in New York.
Former UK Chancellor of the Exchequer George Osborne, who now heads OpenAI for Countries, said: “Protecting civilian infrastructure means defending it from both physical and digital attacks so that people can continue to live, work, and use essential services”.
OpenAI competitor Anthropic tightly restricts access to its models, explaining that they are too powerful and could end up in the wrong hands. OpenAI, by contrast, has allowed a number of European companies and British banks to use its most advanced cyber tools. Jamie McColl, a senior research fellow at the Royal United Services Institute (RUSI), noted that Ukraine already has AI tools from OpenAI competitors, such as Google. Earlier, Anthropic said that Russia-linked hackers used Claude AI agents to attack Ukraine: they downloaded the contents of mailboxes of at least two drone component manufacturers, attacked a military drone manufacturer, and stole the development kit for its computer vision system.
