Nvidia, Microsoft, Meta, IBM and 20+ companies sign public letter urging US lawmakers to avoid restricting open-source AI models, arguing that regulation should target theft rather than impose blanket bans. The move comes as lawmakers propose AI kill switches following a rogue OpenAI cyberattack and Trump's administration weighs sanctions on Chinese open-source makers.

◆ ◆ The Wire takeaway
If you're building on closed-source models, your customers just got a cheaper, safer alternative. Open-source models now have explicit backing from chip makers and cloud platforms to resist kill-switch legislation - meaning the regulatory ground has shifted away from forced restrictions and toward a two-tier market where open wins on cost and closed loses on political ground.
