**The short version**

- The White House has asked OpenAI and Anthropic not to share new AI models with the UK's AI Security Institute.
- This request is for the US government to test and review the models before they are shared with British testers.
- Politico reported the request, citing an informed source and a high-ranking American official.
- A British official confirmed Politico's report to Bloomberg.

The White House has requested that AI companies OpenAI and Anthropic not share their new artificial intelligence models with the UK's AI Security Institute. The request specifies that the US government must test and review the models before they are provided to the British agency. Politico reported the request, citing an informed source and a high-ranking American official. A British official confirmed Politico's report to Bloomberg.

## Disagreement on who made the request

Bloomberg reported that President Donald Trump’s administration requested OpenAI and Anthropic withhold new artificial intelligence models. However, other reports state the request came from the US Office of the National Cyber Director.

## What the coverage left out

None of the left, centre, or right-rated digests mention the specific date the request was made, only that Politico reported it on a Thursday and a British official confirmed it to Bloomberg on a Friday.

## Who covered it

Shares of the 17 covering outlets with a published leaning rating:

- Left: 29% (4)
- Centre: 57% (9)
- Right: 14% (4)

## How the sides framed it

### Left

- The left-rated report led on the White House asking OpenAI and Anthropic not to share new AI models with the UK's AI Security Institute until the US government has tested them. It stated that Politico reported the request, citing an informed source and a high-ranking American official, and that a British official confirmed Politico's report to Bloomberg.

### Centre

- The centre-rated reports led on the White House asking OpenAI and Anthropic to withhold their latest AI models from Britain’s safety watchdog until they have been tested by the US government. One report noted this request threatens the UK’s early access to frontier technology. Another stated the administration wants to review US AI systems for cybersecurity risks before sharing them with British safety testers. One report attributed the request to President Donald Trump’s administration.

### Right

- The right-rated reports led on the White House asking OpenAI and Anthropic not to provide new models to the UK Artificial Intelligence Security Institute until they are reviewed by the US government. One report stated that the White House pressured the companies to reject prior safety verification by a UK laboratory.
