The White House will focus voluntary scrutiny on high-performance closed systems from firms such as OpenAI, Anthropic and Google, while leaving openly downloadable models outside the framework.
The Trump administration has decided to exclude open-weight AI models from a new safety review framework, narrowing oversight to advanced closed systems controlled by individual companies. The move, discussed with major AI firms on August 4, is meant to support a U.S.-centric AI ecosystem while focusing government scrutiny on models with the strongest cybersecurity and hacking capabilities. Reuters and the Wall Street Journal said the draft guidelines would require pre-release government testing for U.S.-developed closed frontier models such as OpenAI's GPT series, Anthropic's Claude and Google's Gemini, but not for open-weight systems including Meta's Llama and Nvidia's Nemotron. The policy builds on President Donald Trump's June AI executive order, which gave developers up to 30 days of pre-release government access in what is formally a voluntary process but is viewed by industry as de facto mandatory. Five companies - OpenAI, Anthropic, Google DeepMind, Microsoft and xAI - already participate in reviews run by the Commerce Department's Center for AI Standards and Innovation. The administration's approach follows recent security incidents involving advanced models and comes as Washington weighs how to respond to China's open-weight progress separately, including possible export controls and procurement restrictions. Critics say the framework remains opaque because the government has not disclosed the full criteria or benchmarks, while supporters argue that exempting open-weight models avoids adding barriers for startups and preserves low-cost access for researchers and enterprises.
