A June executive order gave the US government 60 days — until August 1 — to stand up a voluntary pre-release review process for frontier AI models, with OpenAI, Anthropic, Google, Microsoft and xAI agreeing to take part. The deadline passed with no framework made public, even as the three biggest labs jointly submitted revisions to the draft and Sam Altman visited the White House. (Correction: on August 3 the White House said the framework was in fact completed by the deadline but will not be published — its testing benchmarks are classified — and invited staff from the big AI labs to review it behind closed doors.)
