The tech giant said Ukraine will also gain access to its advanced GPT 5.6 Sol model under the deal. The announcement comes as Ukraine's national cyber incident response team, CERT-UA, reported that the country recorded nearly 6,000 cyber-attacks in 2025 alone.
Daybreak is designed to rapidly identify vulnerabilities in digital systems and help develop fixes, offering a potential force multiplier for Ukraine's overstretched cyber defenders. George Osborne, former UK chancellor and now Head of OpenAI for Countries, said: "Protecting civilian infrastructure means defending it against both physical and digital attacks, so people can continue to live, work and access essential services."
Rafe Pilling, senior director of threat intelligence at cybersecurity firm Sophos, noted that Russian offensive cyber operations have been "a key component" of the Kremlin's aggression against Ukraine since 2014. "Any initiative that strengthens Ukraine's already highly capable, but heavily burdened, cyber defence efforts is a welcome development," he said.
Jamie MacColl, a senior research fellow at the Royal United Services Institute (RUSI), observed that Western tech firms have been supporting Ukraine for some time — partly for altruistic reasons but also because they gain valuable data and intelligence from an active conflict. "Given this, it's no surprise that OpenAI is now also providing defensive cyber security services," he added. MacColl said access to Daybreak would be useful given the volume of Russian cyber-attacks, though he noted Ukraine already had access to AI tools from other providers.
