OpenAI opens Daybreak to Ukraine’s civilian cyber defense

OpenAI said on September 23 that it is extending access to Daybreak, its cyber defense program, to the Government of Ukraine, with the stated goal of supporting the cyber defense of civilian infrastructure. The announcement is a single statement on OpenAI’s site.

OpenAI presents the move as an extension of an existing program. Nothing new is launching. What changes is who can use Daybreak, and the new user is a national government. The BBC’s report makes the same core point. The announcement doesn’t say which Daybreak capabilities Ukraine gets, which systems they cover, how access will be delivered or how long the arrangement runs.

The move comes less than a month after an open letter published on August 27 and signed by more than 100 companies, OpenAI, Anthropic, Amazon Web Services and Microsoft among them. The letter asked frontier AI companies to give defenders access to their most capable models during major cyber incidents. “We have a limited window to strengthen cyber defenses,” it said.
