OpenAI Launches Daybreak to Counter Anthropic's Mythos

OpenAI is launching Daybreak, a cybersecurity AI initiative using its Codex Security agent to identify and patch software vulnerabilities before attackers can exploit them. The initiative will involve industry and government partners as OpenAI deploys increasingly cyber-capable models. The launch directly challenges Anthropic's Claude Mythos, an advanced model capable of finding and generating security exploits. Mythos has raised significant concerns, particularly after a private Discord group reportedly gained unauthorized access on the same day Anthropic announced its limited release to major tech firms.
