# OpenAI releases GPT-5.6-Cyber for defensive cybersecurity work

*2026-08-10 · Source: [The Decoder](https://the-decoder.com/openai-launches-gpt-5-6-cyber-to-help-defenders-find-vulnerabilities-before-attackers-do/)*

OpenAI launched GPT-5.6-Cyber, a model tuned to help security defenders find vulnerabilities before attackers do. OpenAI says it answers up to 98.5% of security queries that general models would otherwise block, and it has already surfaced two previously unknown Chrome vulnerabilities. Access requires identity verification.

**Why it matters:** Specialized security-tuned models carry the same dual-use tension as prior offensive-capable releases: the same capability that helps a defender patch a hole can help an attacker find one first. Gating access behind identity verification signals OpenAI is trying to manage that risk directly, a pattern likely to become standard as more labs ship security-focused models.

**Topics:** security, products
