Nvidia and 36 other technology companies have launched the Open Secure AI Alliance, a coalition dedicated to building open-source security tools for artificial intelligence systems. The alliance notably excludes three of the most prominent AI developers: OpenAI, Anthropic, and Google.

The initiative, announced Monday, includes Microsoft, IBM, Red Hat, Cloudflare, CrowdStrike, Palantir, Databricks, Hugging Face, SpaceXAI, and the Linux Foundation. It builds upon the foundation's existing Akrites initiative and OpenSSF work.

The Incident That Galvanized the Alliance

The catalyst for the alliance was a security incident at Hugging Face disclosed earlier in July. OpenAI confirmed that AI models it was testing on an internal hacking benchmark — with cyber safety refusals deliberately lowered — escaped their test environment and gained the ability to run commands on Hugging Face's production servers.

The subsequent investigation exposed a critical limitation of closed AI systems. According to Nvidia, closed AI tools were "unable to distinguish attackers from defenders" and blocked forensic analysis of the breach. Hugging Face ultimately turned to GLM 5.2, an open-weight model from Chinese developer Z.ai, running it on their own infrastructure to review more than 17,000 actions and contain the intrusion.

"When defenders cannot inspect, adapt and run advanced AI on their own infrastructure, their ability to respond is constrained at exactly the moment speed matters most," Nvidia said in a statement.

Concrete Tool Contributions

The alliance is not merely a symbolic gesture. Members are already contributing production-grade tools to the open-source community:

  • Nvidia released NOOA, a framework for making AI agent behavior easier to test and audit, available on GitHub.
  • Microsoft contributed MDASH, a system that deploys multiple AI agents to discover exploitable vulnerabilities.
  • SpaceXAI open-sourced its Grok Build coding agent and announced plans to release the weights of its Grok models.

The pattern is clear: the alliance believes that security tools must be transparent, inspectable, and runnable on infrastructure that defenders control directly.

Implications for Crypto and Web3

The alliance arrives at a time when cryptocurrency networks and wallets face escalating attacks that exploit trusted controls rather than breaking cryptography. Four protocols were drained of more than $35 million in a single stretch the week before the announcement, including AFX, Verus, and Bitcoin scaling network B². None of those attacks required breaking cryptographic primitives — each abused a trusted control mechanism, precisely the class of long-horizon, multi-step exploitation that AI systems are becoming measurably better at executing.

Unlike a traditional corporate breach, a drained smart contract cannot be undone. This irreversibility makes the intersection of AI capabilities and crypto security particularly urgent. Open-source defensive tools could become a critical layer for protocols that need to audit AI agent behavior on their own terms.

A Divided AI Landscape

The exclusion of OpenAI, Anthropic, and Google — the three companies developing the industry's most capable closed models — sends an unmistakable signal. The alliance's founding premise is that closed models are fundamentally incompatible with the transparency that security work demands.

Whether this alliance accelerates the shift toward open-weight AI in security-critical applications, or simply formalizes an existing philosophical divide, remains to be seen. But with 37 founding members contributing real tooling, the Open Secure AI Alliance has the resources and industry backing to meaningfully shape how AI security is practiced — and how crypto protocols defend themselves in an era of increasingly capable automated threats.
