OpenAI is giving Ukraine's government access to its Daybreak cyber defense program as Russian attacks continue to disrupt civilian infrastructure across the country.
In a statement on Wednesday, the ChatGPT maker said that it will work with Ukraine's Ministry of Digital Transformation to provide tools for identifying software vulnerabilities and testing fixes.
The announcement was made on the sidelines of the UN General Assembly by Dmytro Kushneruk, Ukraine's Consul General in San Francisco, and Sasha Baker, OpenAI's head of national security policy.
Ukraine's national cyber incident response team handled nearly 6,000 incidents in 2025, according to OpenAI. Those incidents included attacks on hospital systems, the energy sector, and telecommunications.
The move comes as Russian attacks continue to affect communications infrastructure. On Sept. 23, Russian drone strikes disrupted internet services for about 100,000 households in Kyiv and the surrounding region, according to Reuters citing official data.
OpenAI said Daybreak is designed for authorized security work, including reviewing older software, investigating suspicious activity, validating vulnerabilities, and testing fixes.
"Through Daybreak, public and private entities have an opportunity to strengthen their cyber defenses before emerging threats take hold," Baker said. "Ukraine is already on the front line, and its defenders need support now."
The company has previously made its cyber models available to defenders in France, Germany, Poland and other European countries, according to the statement. The EU's cyber agency, ENISA, used the models to identify vulnerabilities in software used across EU institutions, all of which were subsequently fixed.
In Poland, CERT Polska used OpenAI models to identify six vulnerabilities in third-party router software. The vendor released fixes that CERT Polska said prevented the attacks it had observed.
