According to OpenAI, while GPT-5.6-Sol is highly advanced, its refusal rate is high for penetration testing against production systems and other dual-use cyber prompts that could be used for both good and evil.
GPT-5.6-Cyber should address these issues, and testing conducted by the vendor showed a 95% completion rate for prompts involving exploit chain development, privilege escalation, and authentication bypass, compared with 1.5% for GPT‑5.6 Sol.
“It also completes more requests than GPT‑5.5‑Cyber, which completes only 57.3% of requests, addressing feedback from security...
