Nvidia, Microsoft, Meta warn against 'premature restrictions' of open-weight models

Major tech companies including Nvidia, Microsoft, and Meta released a letter urging policymakers against restricting open-weight AI models (models whose code and weights are publicly available for anyone to download and modify), arguing that such restrictions would reduce competition and drive innovation elsewhere. The letter counters concerns about Chinese AI models outperforming American alternatives, noting that open-weight models actually enhance security and prevent AI capabilities from being concentrated in a few companies.
