White House Tells OpenAI and Anthropic to Withhold Models From UK's Testing Agency

NathanpmYoung · x · 2026-09-25

Per a scoop, the White House has asked OpenAI and Anthropic not to share their AI models with the UK government's testing agency UKAISI until the models have gone through US testing. "Because they're American companies and this has been our policy with every new frontier model," a senior official said. The preferred sequence: US review, then secure US systems, then sharing with US partners. Anthropic appears to have complied; OpenAI hasn't said. Reports also suggest the White House is working to cut off UKAISI, with CAISI expected to be renamed.
