White House Tells OpenAI and Anthropic to Withhold Models From UK AISI Until US Testing

dioscuri · x · 2026-09-25

Scoop: The White House has asked OpenAI and Anthropic not to share new models with the UK government's testing agency AISI until they pass US review, citing policy for American companies. Anthropic has complied; OpenAI hasn't said. Critics note UK AISI is the world's leading government evaluator, having caught vulnerabilities in nearly every major frontier release, and call the move a senseless step backward for allied pre-deployment testing.
