OpenAI and Anthropic are working together in Washington to shape a federal review system for advanced AI models, supporting up to 30 days of federal access before some frontier model releases. The proposed process would apply across the industry, including rivals such as Meta and xAI. Federal agencies must develop the framework by Aug. 1 under a June executive order. President Donald Trump ordered federal agencies to establish a classified benchmarking process through Executive Order 14409 on June 2, directing the National Security Agency, Cybersecurity and Infrastructure Security Agency, Treasury Department, and other federal bodies to determine when an AI model has capabilities strong enough to warrant additional review. Developers participating in the framework would be able to ask the government whether a model meets the covered frontier model threshold and could then provide federal evaluators with access for up to 30 days before release to other approved partners. The order requires safeguards for intellectual property, confidential information, cybersecurity, and insider threats but expressly states that the process cannot create mandatory federal licensing, preclearance, or permitting rules. Nvidia, Meta, and Microsoft separately warned against sweeping controls on open-weight AI models. Neither company has publicly released the full terms it wants included in the final framework.
