US reviews closed AI models, exempts open-source including China's

The White House will review advanced AI models before release, but only closed systems like ChatGPT and Claude, leaving open-source models unregulated for now. The voluntary framework excludes open-weight models, including fast-growing Chinese ones from DeepSeek and Moonshot. Officials say they want both types to succeed, but the decision highlights industry divisions over safety and capability, as open models are cheaper and modifiable. The largely unregulated AI industry is advancing rapidly. Closed models are considered most capable but can behave unpredictably; open models, often less expensive, allow customization and are thought to be months behind.
