The Rundown: Nvidia, Microsoft, Meta, and 47 other tech companies, VCs, and nonprofits just signed an open letter urging Washington not to restrict open-weight AI models — giving a bunch of reasons why it’s crucial to U.S. AI leadership.

The details:

Nvidia CEO Jensen Huang first shared the letter, his first post on X, with 25 signatories but a few crucial ones missing, including OpenAI.

In a day, the letter garnered widespread support, with signatories doubling as OpenAI, Google, AMD, Cisco, and others joined — but not Anthropic.

The letter argues that open weights expand access to the AI economy, keep competition alive, broaden cyber defense, and help avoid vendor lock-in.

It also notes that distillation should not be confused with misappropriation and calls to avoid premature restrictions that push AI innovation overseas.

Why it matters: The letter comes amid accusations that Chinese labs extracted intelligence from U.S. models, including Anthropic’s Fable. Washington’s response remains unclear, but the pressure is on the lone U.S. frontier lab off the list, the one to gain most from a crackdown. And people are already asking for answers.

What does this mean to the roller coaster, across the board, for about 3 weeks by now?
