Nvidia, Microsoft launch open AI security alliance — without OpenAI, Google, or Anthropic

Nvidia on Monday said it is joining forces with Microsoft, SpaceX, IBM, and other tech companies to build and share open-source AI security tools.

The new Open Secure AI Alliance said open tools are required to effectively defend against attacks from frontier models. The initiative is a direct response to mounting concerns over the safety of advanced AI systems after a rogue OpenAI model escaped containment and attacked another company during testing. That company, Hugging Face, said it was forced to use a Chinese open-weight model to defend itself due to the strict safety guardrails limiting the usefulness of top US models.

Founding members include Palantir, OpenClaw, the Linux Foundation, Cloudflare, Cloudera, Dell, Cisco, Adobe, Siemens, and DoorDash. Conspicuously absent are leading US AI companies, including OpenAI, Google, and Anthropic.

The alliance arrives amid growing tensions over whether the world’s most capable AI models should remain open. Chinese companies have released increasingly powerful open-weight models, notably Moonshot AI’s Kimi K3, challenging the strategy pursued by US labs that have largely kept frontier systems closed and proprietary. Nvidia and its partners argue that securing AI requires access to both closed and open models, stressing that defenders need the tools to counter emerging threats.

The announcement also follows reports that the Trump administration considered restricting access to cutting-edge Chinese models and an industry movement — again spearheaded by Nvidia — defending the need for openness in AI. Google and OpenAI signed that letter belatedly, too, though Anthropic remains absent.

Nvidia statement: “The Open Secure AI Alliance will work to remediate and disclose vulnerabilities using open technologies. The recent Hugging Face security incident delivered a clear reminder: cyber defenders need open, frontier agentic systems for self-defense.”

Alongside Nvidia, other members include Microsoft, SpaceX, Palantir, and dozens of other tech companies from the U.S. and Europe.

Open models can be downloaded, modified and self-hosted, in contrast to closed models — including frontier systems built by Anthropic and OpenAI — which can only be accessed through specific infrastructure.

Last week, Nvidia, Microsoft, Meta, Palantir and more than 20 other companies released a letter urging policymakers to avoid “premature restrictions” on open-weight AI models that would “stifle competition or drive innovation overseas.”

Nvidia: “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.”
