Sources: the White House asked OpenAI and Anthropic not to share new models with UK's AISI until US reviews them; Anthropic appears to have agreed
The White House has asked OpenAI and Anthropic not to share their new artificial intelligence models with the U.K. government's testing agency until …
Context & Ripple Effects
OpenAI and Anthropic had already agreed in 2024 to give the US AI Safety Institute early access to major models for capability and risk testing. The reported effort to sequence UK access behind US review turns that voluntary safety-testing arrangement into a point of bilateral control.
The move follows both labs' reported Washington lobbying for government model-review requirements that also cover lagging competitors and their reported push to constrain open-source models. Public reaction focused on whether delaying UK testing would weaken an allied safety body's practical role.
First-order effects
- The reported White House request puts the UK's AISI behind the US review process for new OpenAI and Anthropic models; Anthropic reportedly agreed to that sequencing.
- US AI safety reviewers gain first access to the two labs' new models under the reported arrangement, reinforcing the early-access role they secured in 2024.
Second-order effects
- UK AISI's ability to independently test frontier models on the same timetable as US reviewers depends on whether the companies comply with the requested delay.
- For OpenAI and Anthropic, compliance ties model-release oversight more closely to Washington at the same time they are seeking broader government review obligations for rivals.
Third-order effects
- If this access-ordering pattern holds, frontier-model evaluation becomes an instrument of AI sovereignty: governments compete not only over rules but over who sees models first.
- The episode points toward a state-compatible AI-lab model in which access to leading systems is allocated through national-security and industrial-policy relationships rather than shared among allied evaluators.
The trend: Frontier-model access is becoming a geopolitical control point, with national review priority shaping the authority of AI safety institutions.
