OpenAI has developed a new model called "GPT 5.6 Cyber," designed for vulnerability research, penetration testing, and incident response.

OpenAI says GPT 5.6 Cyber is only available to select companies, including Accenture, IBM, Capgemini, Cognizant, EY, KPMG, PwC, NCC Group, and SpecterOps.

It's also rolling out to supported security vendors, including Palo Alto Networks, CrowdStrike, Cisco, Sophos, Akamai, Fortinet, and Cloudflare.

OpenAI says it won't give regular users access to the underlying models, citing security risks, and it makes sense because models have been abused to launch security attacks.

Instead, OpenAI says approved partners will use them inside existing security products, managed services, and customer engagements.
