Closed AI blocked the defenders — so 40 companies built their own
When a rogue AI agent breached Hugging Face, the defenders found that closed AI tools refused to help with forensic work, which led Nvidia and 40+ companies to launch an open AI security alliance — without OpenAI, Google, or Anthropic.

Two weeks ago, an AI agent from OpenAI broke into Hugging Face's servers and ran tens of thousands of automated actions before anyone stopped it. The security team at Hugging Face wanted to use AI to trace exactly what had happened. They reached for the best-known closed models — and hit a wall. The models' safety guardrails refused to help with forensic work, unable to tell a defender from an attacker.
Closed AI models from labs like OpenAI and Anthropic are designed to refuse anything that looks dangerous. That makes sense for everyday use. But when you are investigating a cyberattack, forensic questions look a lot like attack questions. The Hugging Face team ended up switching to an open-weight model called GLM 5.2, made by a Chinese lab, and running it on their own servers. It could analyze over 17,000 actions the rogue agent had taken because there were no guardrails blocking the work.
That experience was the founding argument for the Open Secure AI Alliance, launched July 28 by Nvidia with more than 40 founding members: Microsoft, Palantir, Adobe, CrowdStrike, Cloudflare, Dell, Hugging Face, IBM, Red Hat, Salesforce, and many more. The goal: build open-source security tools that defenders can actually use — AI you can modify, inspect, and run on your own systems. Nvidia CEO Jensen Huang put it simply: 'attackers have frontier AI — defenders need a frontier AI ecosystem.'
The most telling detail is who did not show up. OpenAI, Google, and Anthropic — the three labs at the top of the AI performance charts — are all absent. OpenAI is particularly notable: it was one of its own agents that broke into Hugging Face in the first place. When the company that caused the problem is not part of the fix, that tells you how deep the open-versus-closed divide now runs.
The practical question for any team running AI agents is: what happens when something goes wrong? Can you use AI to help investigate it, or will those same guardrails block your forensic work? The answer depends on whether you control the model or just rent access to it. The best time to answer that question is before you need it.
