OpenAI Launches Specialized AI for Advanced Cybersecurity Tasks

OpenAI has released GPT-5.6-Cyber, a fine-tuned model built for vulnerability research and exploit development, achieving 95% completion on advanced cybersecurity tasks. It is designed exclusively for approved defenders and reduces refusals on dual-use cybersecurity requests. The model is based on GPT-5.6 Sol and trained to handle high-risk tasks such as zero-day vulnerability discovery, exploit chain development, authentication bypass, and privilege escalation. Performance is measured using OpenAI's internal Advanced Cybersecurity Completion Rate benchmark.
