OpenAI Daybreak: Secure-by-Design LLMs for Developers
🔒 OpenAI has launched Daybreak, an initiative built on its frontier LLMs and the Codex assistant to help developers embed security throughout the software development lifecycle. Announced on May 12, Daybreak extends the Trusted Access for Cyber (TAC) program and includes GPT‑5.5, TAC-enabled GPT‑5.5, GPT‑5.5‑Cyber and a Codex Security research preview. The initiative supports code scanning, vulnerability triage, automated detection and response while pairing defensive capabilities with verification, proportional safeguards and accountability.
