OpenAI Will Arm Critical Cyber Defenders With Frontier Model

OpenAI will start rolling out a frontier cybersecurity model called GPT-5.5-Cyber to “critical cyber defenders” within days, CEO Sam Altman said in a Wednesday (April 29) post on X.

“We will work with the entire ecosystem and the government to figure out trusted access for cyber; we want to rapidly help secure companies/infrastructure,” Altman wrote.

OpenAI announced in a Wednesday blog post that the company released an Action Plan that describes how it will build the infrastructure needed to support cybersecurity defenders and will provide trusted actors across society with access to defensive tools.

The company’s plan includes democratizing cyber defense, coordinating across government and industry, strengthening security around frontier cyber capabilities, preserving visibility and control in deployment, and enabling users to protect themselves.

OpenAI said in its post that as AI reshapes cybersecurity, criminals are deploying the same capabilities as defenders.

“Building resilience in the Intelligence Age will require both working through democratic institutions and processes, and broadening access to the technologies that can help protect communities, critical systems and our national security,” OpenAI said in the post.

It was reported April 21 that OpenAI has begun briefing state and federal government officials on the capabilities of its cybersecurity product. The AI startup held an event in Washington, D.C., where it demonstrated a new model to officials from throughout the government and from various national security agencies.

The company is taking a dual-track approach, making one version of its model more widely available with robust safeguards, and another more permissive version for cyber defenders through its Trusted Access program. This tactic will let more companies, like local water utilities, access advanced AI tools.

OpenAI said April 14 that it plans to expand access to the Trusted Access for Cyber (TAC) program, which it introduced in February, to give cybersecurity professionals access to frontier models.

The company said it is scaling up TAC to thousands of verified individuals and hundreds of teams responsible for defending critical software.

“In preparation for increasingly more capable models from OpenAI over the next few months, we are fine-tuning our models specifically to enable defensive cybersecurity use cases, starting today with a variant of GPT-5.4 trained to be cyber-permissive: GPT-5.4-Cyber,” OpenAI said in an April 14 blog post.
