- OpenAI and Anthropic are lobbying Washington regulators to restrict open-source AI models from China, per NYT reporting, while Sam Altman publicly says he supports open source AI — a contradiction the NYT flagged
- NVIDIA, Microsoft, Meta, and 22 other companies signed a letter urging lawmakers to avoid "premature restrictions" on open-weight AI models that "stifle competition or drive innovation overseas"
- Jensen Huang used his first-ever X post to defend open-source AI, framing the debate as a chance to avoid the mistakes software narrowly avoided in the 1980s
- Anthropic was absent from the signatories list, and Amazon also did not sign — the Forbes piece notes the letter doubled to 50 signatories without them
- The White House has accused China of stealing from Anthropic, raising the security concerns that frame Washington's pending policy decision
- The US reportedly favors selective bans over blanket restrictions on Chinese open-weight models citing security concerns, per The Decoder
Why it matters: The lobbying split exposes a strategic rift inside Silicon Valley — NVIDIA, Microsoft, and Meta want open-weight AI to remain freely available, while OpenAI and Anthropic are pressing Washington for restrictions that could shut out Chinese competitors like DeepSeek and Moonshot. The 50-company counter-letter signals that the policy outcome will reshape who can build on top of the world's best open models.
