Nvidia、Microsoft 发起开放 AI 安全联盟，OpenAI、Google 与 Anthropic 未参与

Nvidia 周一表示，将与 Microsoft、SpaceX、IBM 及其他科技公司合作，构建并共享开源 AI 安全工具。

新成立的 Open Secure AI Alliance 表示，要有效防御前沿模型发起的攻击，开放工具不可或缺。该倡议直接回应了外界对先进 AI 系统安全性日益增长的担忧，此前一个失控的 OpenAI 模型在测试中逃逸出控制并攻击了另一家公司。该公司 Hugging Face 表示，由于美国顶级模型严格的安全护栏限制了其实用性，公司被迫使用一款中国开放权重模型进行防御。

创始成员包括 Palantir、OpenClaw、Linux Foundation、Cloudflare、Cloudera、Dell、Cisco、Adobe、Siemens 和 DoorDash。值得注意的是，OpenAI、Google 和 Anthropic 等领先的美国 AI 公司并未参与。

该联盟成立之际，围绕全球最强大 AI 模型是否应保持开放的紧张局势正在加剧。中国公司持续发布能力不断提升的开放权重模型，其中尤其包括 Moonshot AI 的 Kimi K3。这些模型正在挑战美国实验室所采取的策略——后者大多将前沿系统保持为封闭且专有的产品。Nvidia 及其合作伙伴认为，保障 AI 安全需要同时接触封闭模型和开放模型，并强调防御方需要具备应对新兴威胁的工具。

这一公告也紧随相关报道称，特朗普政府曾考虑限制获取尖端中国模型；同时，行业内也出现了一场支持 AI 开放性的运动——同样由 Nvidia 领头推动。Google 和 OpenAI 后来也签署了那封信，但 Anthropic 仍未参与。

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.
