NVIDIA CEO Jensen Huang is urging US lawmakers not to impose strict limits on open-weight AI, which allows users to download and modify the technology. His comments follow the launch of the Kimi K3 model by Chinese company Moonshot AI, which has sparked concerns about a regulatory crackdown. Huang stated, "For the American industry, we need open weight for security, we need open weight for safety." With China now rolling out competitive and cheaper open-weight models like Kimi K3, NVIDIA, Microsoft, and Palantir warn that restricting these tools could concentrate too much power in a few hands and weaken cybersecurity amid intensifying global competition.
