With three days left before the first formal deadline in U.S. history for government oversight of frontier AI model releases, OpenAI and Anthropic have been working together in Washington to shape the rules, pushing the Trump administration to adopt a consistent federal review process for the most powerful AI models that would apply to rivals including Meta and Elon Musk's xAI. On July 28, more than 1,100 employees across OpenAI, Anthropic, Google, Meta, and nearly a dozen other firms circulated an open letter calling on the U.S. government to support an international mechanism to deliberately pace AI development, warning there is "a real risk" that AI progresses faster than people can "understand or control." The leading labs want predictable rules applied to everyone, and a significant portion of their own workforces now publicly agrees the technology may be outrunning governance. Neither company has publicly released the full terms it wants included in the industry-wide review standard proposal, but their shared position is that pre-release review standards should apply across the industry, bringing Meta and xAI under the same framework if their models cross the threshold. By co-authoring the threshold definitions from inside the process, OpenAI and Anthropic gain a structural advantage that rivals who were not in the room do not have.
