OpenAI’s GPT‑5.6 Cyber model lets defenders hunt zero‑days via gated Red tier
OpenAI’s new GPT‑5.6 Cyber model is purpose‑built for defensive security tasks—code review, malware analysis, and even zero‑day discovery—available through the gated Daybreak Red tier. In internal tests it answered 95% of exploit‑chain requests, far outpacing the standard GPT‑5.6 Sol, but its reports are shorter and cost more tokens.
