OpenAI, Anthropic, and Google appear to be the primary companies subject to the new requirements, given their leadership in closed-model development. The White House discussed the framework Tuesday with executives from these firms as well as Meta and Nvidia. The specific triggers for mandatory review—which models qualify as frontier systems and what benchmarks determine risk—remain unclear.
The framework implements a June 2026 executive order directing government development of a benchmarking-based security review process. By carving out open-weight models, the administration has signaled a narrower approach focused on the most advanced closed systems. Attorneys advising AI developers should monitor how the government defines "frontier" capabilities and what the actual review timeline and criteria will be, as these details will determine compliance obligations and competitive implications for their clients.
