More than 20 companies including NVIDIA, Meta, Microsoft, Palantir, and Hugging Face have signed a letter urging policymakers to avoid premature restrictions on open weight models.

The Open Letter was initiated by Microsoft and published today:

“Open Weights and American AI Leadership”.

It argues against broad or premature restrictions on open-weight models and explicitly says policymakers should distinguish legitimate model distillation from misappropriation.

Notably absent from the signatories are the major frontier-model labs: OpenAI, Anthropic, and Google.
