AI Summary

OpenAI unveiled Daybreak, an AI‑driven security initiative that aims to locate and fix software vulnerabilities before they can be exploited. The program builds on the Codex Security AI agent introduced in March, which constructs a threat model from an organization’s code, maps potential attack paths, validates likely flaws, and automates detection of high‑risk issues. Daybreak’s debut follows Anthropic’s earlier announcement of Claude Mythos, a security‑focused model that Anthropic kept private due to safety concerns, though some unauthorized actors reportedly obtained it. The rollout positions OpenAI to compete directly in the emerging AI‑security market.
