Summary

Anthropic has refused to submit its latest AI model for safety testing by the UK’s top AI safety institute, raising concerns about oversight in the field of advanced artificial intelligence. This decision comes amid growing transparency issues, particularly regarding the U.S. government’s AI security framework, which has not been made public despite requests from various organizations. These groups argue that a lack of transparency could erode public trust in AI governance. On Wednesday, Anthropic announced it would provide extensive access to another institute for reviewing cybersecurity incidents at OpenAI.
