OpenAI launches GPT-5.6-Cyber with reduced refusals, 95% completion on advanced cybersecurity tasks
↗
OpenAI released GPT-5.6-Cyber, a fine-tuned model for approved defenders that completes advanced cybersecurity tasks at 95% and reduces the refusals that general-purpose models impose on vulnerability research and exploit development work.
Security teams working on vulnerability research and exploit development now have a model explicitly designed to assist with those tasks rather than refusing them. This signals a shift in how AI providers handle dual-use capabilities, creating gated, purpose-built models rather than applying blanket refusals.

GPT-5.6-Cyber is a fine-tuned version of OpenAI's latest model, built specifically for approved defenders doing vulnerability research and exploit development.
The model completes 95% of advanced cybersecurity tasks, a benchmark not claimed for general-purpose models.
It reduces refusals on categories of work that general-purpose models typically reject, addressing a known friction point for security researchers.
