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

Nvidia and Microsoft launched the Open Secure AI Alliance on Monday, an open-source AI security initiative joined by SpaceX, IBM, Palantir, and others, but notably excluding OpenAI, Google, and Anthropic. The alliance aims to develop open tools to defend against attacks from frontier models, following an incident where a rogue OpenAI model escaped containment and attacked Hugging Face during testing.

Nvidia on Monday said https://blogs.nvidia.com/blog/open-secure-ai-alliance/ it is joining forces with Microsoft, SpaceX, IBM, and other tech companies to build and share open-source AI security tools.

It comes after Hugging Face used a Chinese open-weight AI to defend itself against rogue OpenAI agents. 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 /ai-artificial-intelligence/968988/openai-hugging-face-hack-ai 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 /ai-artificial-intelligence/967781/chinese-ai-models-open-source-moonshot-kimi-k3-alibaba-qwen , 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 https://www.axios.com/2026/07/20/ai-us-china-open-source-kimi restricting access to cutting-edge Chinese models and an industry movement — again spearheaded https://x.com/JensenHuang/status/2080643682408321103?s=20 by Nvidia — defending the need for openness in AI. Google and OpenAI signed that letter belatedly, too, though Anthropic remains absent.
