OpenAI just released its answer to Claude Mythos

OpenAI launched Daybreak, a cybersecurity AI initiative built with Codex, its models, and security partners.

Daybreak is designed to model threats from code, map likely attack paths, validate vulnerabilities, and automate detection of high-risk issues.

The effort comes after Anthropic’s Claude Mythos under Project Glasswing, highlighting rising competition in AI security.

OpenAI said it is also working with industry and government partners and expanding its cyber-capable models.
