The announcement underscores a broadening shift as AI companies are increasingly pushing into cybersecurity as advanced models improve at analyzing code, finding software weaknesses, and automating technical tasks.
“AI is already good and about to get super good at cybersecurity; we'd like to start working with as many companies as possible now to help them continuously secure themselves,” Altman wrote.
According to OpenAI, Daybreak combines the company’s AI models with Codex, its coding-focused agentic system, to help security teams review code, analyze dependencies, model threats, validate patches, and investigate unfamiliar systems. The company said the goal is to reduce the time between identifying a vulnerability and fixing it.
OpenAI did not immediately respond to a request for comment by Decrypt.
“AI can now help defenders reason across codebases, identify subtle vulnerabilities, validate fixes, analyze unfamiliar systems, and move from discovery to remediation faster,” OpenAI said in a statement. “Because those same capabilities can be misused, Daybreak pairs expanded defensive capability with trust, verification, proportional safeguards, and accountability.”
"Daybreak is the first glimpse of sunlight in the morning," OpenAI wrote. "For cyber defense, it means seeing risk earlier, acting sooner, and helping make software resilient by design."
