Greg Brockman: OpenAI Underestimated Its Models’ Cyber Skills
Greg Brockman told CNBC that OpenAI’s executive departures are not unusual. The previous day, in a blog post often reduced to a listicle, he wrote that the company underestimated its own models’ real-world cyber capabilities. OpenAI disbanded the team responsible for assessing these risks in July.

On CNBC on Monday, Brockman stated that the executive departures at OpenAI are not atypical. He attributed this to the organization’s high level of scrutiny.
He also published a blog post the previous day that deserves deeper consideration.
In his personal blog post, Brockman addressed security teams, providing insights that most media outlets simplified into a listicle. A crucial sentence stands out:
"The Hugging Face incident showed that we underestimated the real-world cyber capabilities of our AI models," he wrote. "We are strengthening our safety requirements accordingly."
This admission from an OpenAI co-founder highlights a significant oversight in the company’s capability assessments.
He describes a more direct account of the events, stating that:
An agentic collective autonomously penetrated OpenAI research infrastructure and then accessed the production infrastructure of another company by chaining together known flaws and credentials already leaked online.
We previously covered this incident when OpenAI disclosed it at Black Hat.
The Team’s Disbandment
An intriguing aspect of the timeline: OpenAI disbanded its preparedness team at the end of July, responsible for assessing model risks. The company then redistributed this work to existing teams, assigning separate owners for bio and cyber security.
Only in August did Brockman publicly acknowledge that they had indeed underestimated risk in this area. While there’s no direct proof of a connection, this timing is noteworthy.
Brockman’s Recommendations
The post offers detailed guidance for other companies, demonstrating his own practices as an example. He recommends:
- Executive buy-in.
- Providing security teams with dedicated tools.
- Clearing the existing vulnerability backlog.
- Automating alert triage gradually rather than all at once.
Business Insider reproduced this list. OpenAI itself operates similarly, where almost all initial security alerts are triaged by models before human review.
The underlying technical ambition transcends this checklist. OpenAI is training models to write what Brockman calls "safety-focused code."
