OpenAI Gives Ukraine Access to Daybreak AI Cyber-Defense Tool

In brief

• OpenAI will give Ukraine's Ministry of Digital Transformation access to Daybreak, its AI tool for finding and fixing software vulnerabilities.
• Ukraine's CERT-UA handled nearly 6,000 cyberattacks in 2025, a 37% increase from 2024, with local governments and government agencies hit hardest.
• The offer follows OpenAI's September 3 pledge of $1 billion in subsidized Daybreak access, which promised expansion to "partner countries" within weeks.

OpenAI is giving Ukraine's government access to Daybreak, an AI tool built to hunt down software vulnerabilities—the hidden coding flaws hackers exploit to break into a system—before Russian hackers find them first.

The offer went to Ukraine's Ministry of Digital Transformation and was announced Wednesday on the sidelines of the UN General Assembly. Dmytro Kushneruk, Ukraine's Consul General in San Francisco, and Sasha Baker, OpenAI's Head of National Security Policy, made the announcement together.

Daybreak runs on GPT-5.6 Sol, OpenAI's flagship large language model—the same kind of AI that powers ChatGPT, trained on huge volumes of text and code so it can read software the way a human expert would. It scans aging systems for weak points, checks whether a suspected flaw is actually exploitable, and confirms a patch actually closes the hole before anyone ships it.
