OpenAI has officially launched its Trusted Access for Cyber program, expanding access to its specialized GPT 5.4.
The Cyber model applies to a broad range of organizations committed to strengthening global cyber defense. The initiative is built on a straightforward principle.
Advanced AI-powered cybersecurity capabilities should be widely accessible to defenders, but access must scale alongside trust, validation, and appropriate safeguards.
OpenAI Cyber Access Program
Rather than offering unrestricted access, OpenAI is scaling participation based on an organization’s demonstrated security posture and accountability.
The program targets a wide spectrum of defenders from large enterprises and security vendors to open-source researchers, nonprofits, and smaller teams with limited security resources.
The company emphasizes that cybersecurity is a collective effort and that real-world protection depends on organizations of all sizes working together.
Recognizing that many teams lack dedicated, round-the-clock security personnel, OpenAI has committed $10 million in API credits through its Cybersecurity Grant Program.
The funding aims to help software developers and security researchers access frontier AI capabilities regardless of organizational size.
Initial grant recipients include:
- Socket and Semgrep — focused on software supply chain security
- Calif and Trail of Bits — pairing frontier AI models with expert vulnerability researchers
OpenAI is actively seeking additional partners with a proven track record in identifying and remediating vulnerabilities across open-source software and critical infrastructure. Several globally recognized enterprises have already signed onto the program.
Participants include Bank of America, BlackRock, BNY, Citi, Cisco, Cloudflare, CrowdStrike, Goldman Sachs, iVerify, JPMorgan Chase, Morgan Stanley, NVIDIA, Oracle, Palo Alto Networks, SpecterOps, and Zscaler.
These organizations represent some of the most complex digital environments in operation today, spanning financial services, cloud infrastructure, cybersecurity, and enterprise technology sectors.
Government AI Safety Institutes
OpenAI has also provided GPT-5.4-Cyber access to the U.S. Center for AI Standards and Innovation (CAISI) and the UK AI Security Institute (UK AISI).
Both agencies will conduct independent evaluations of the model’s cyber capabilities and built-in safeguards, adding a critical layer of government-level oversight to the initiative.
OpenAI has stated that the program will continue to expand as real-world learning accumulates, with safeguards designed to increase in proportion to capability.
The company encourages participants to push the boundaries of defensive research, share discoveries openly, and help translate new insights into stronger protections across the ecosystem.
The program reflects OpenAI’s broader position that AI-enabled cyber defense is a shared responsibility, one that demands participation from the full breadth of organizations protecting the world’s digital infrastructure.
