Anthropic AI Models Blocked
Anthropic has been forced to block access to its newest AI models due to export control rules. The restriction affects all users, including foreign nationals and US-based employees.

Anthropic, a leading AI development company, has faced a significant setback with its newest AI models being taken offline. The decision to block access was made after the Trump administration ordered the company to restrict access for all foreign nationals. This move has not only affected users outside the US but also Anthropic's own employees based in the country. As a result, models such as Fable 5 and Mythos 5 are currently inaccessible. The export control rules have raised concerns about the understanding and implementation of such regulations. The situation highlights the complexities and challenges that AI companies face in navigating export control laws.
