- Two dozen companies and organisations signed an open letter to US policymakers urging protection for open-weight AI.
- Signatories include direct commercial rivals such as Meta, Microsoft, Nvidia, IBM, and Dell.
- The letter argues that closed models create single points of failure and block independent security oversight.
- Signatories advocate for addressing model misappropriation via targeted legal measures rather than banning distillation.
Two dozen companies and organisations have signed an open letter urging US policymakers to protect open-weight AI models from restrictive regulations.
The letter carries signatures from a diverse group that spans direct commercial rivals and organisations with distinct business models, including Meta, Microsoft, Nvidia, IBM, Dell Technologies, CrowdStrike, Palantir, ServiceNow, Hugging Face, Perplexity, Mistral, Andreessen Horowitz, Y Combinator, the Linux Foundation, and Mozilla.
The argument centres on drawing a parallel between the open-source software movement of the 1980s and the modern debate over whether AI model weights should circulate freely or remain locked behind commercial APIs. Open-weight models are AI systems where trained parameters are published for anyone to download, inspect, modify, and run locally, distinguishing them from closed frontier products offered strictly via API access.
The unusual alliance of major hardware providers and software platforms highlights a shared economic interest. Infrastructure giants like Nvidia, IBM, and Dell benefit directly from a flourishing open-weight ecosystem because a wider array of deployable models drives higher demand for compute and cloud services, regardless of which lab trains the weights.

The signatories frame open weights as the essential mechanism for spreading AI capabilities beyond a handful of well-capitalised labs into everyday workflows across factories, hospitals, farms, and classrooms. Addressing security directly, the letter argues that closed models are not inherently safer because they can still be breached or fail in ways external researchers cannot observe, effectively concentrating advanced capabilities into single points of failure.
Furthermore, the letter carves out space for the controversial technique of distillation, where one model's outputs help train another. Rather than imposing blanket restrictions on standard machine learning practices, the signatories suggest addressing any potential misappropriation through targeted legal and commercial mechanisms.
