A week after the artificial intelligence company Anthropic said it would limit the release its latest A.I. technology to a small number of trusted organizations because of cybersecurity concerns, OpenAI said on Tuesday that it too is sharing a similar technology with only a group of partners.

OpenAI, the maker of ChatGPT,

said in a blog post

that it would initially share a new A.I. model called GPT‑5.4‑Cyber with hundreds of organizations, before expanding the release to thousands of additional partners in the coming weeks.

“Our goal is to make these tools as widely available as possible while preventing misuse,” the company said. “We aim to make advanced defensive capabilities available to legitimate actors large and small, including those responsible for protecting critical infrastructure, public services, and the digital systems people depend on every day.”

Like Anthropic’s technology, Claude Mythos Preview, GPT-5.4-Cyber is designed to identify security holes in software. Like other tools developed across the long history of cybersecurity, the technology can be used to both attack computer networks and defend them.

By releasing the technology to a smaller group, OpenAI, like Anthropic, hopes to give defenders an edge over attackers. Before Anthropic unveiled Mythos last week, Zico Kolter, an OpenAI board member, called for such an approach in an interview with The New York Times.

“Four or five months ago, we had a step change in what these systems could do,” said Dr. Kolter, a professor of computer science at Carnegie Mellon University who specializes in security and A.I.
