Anthropic has suspended access to its most advanced AI model due to security concerns. The decision was made in response to a recent directive related to national security in the United States. The company has chosen to restrict access to its models, Fable 5 and Mythos 5, for all clients.

This move is intended to comply with the directive, which aims to limit access to the models outside of the US or by foreigners within the country. Further information on this development can be found in the original report from El Mundo, which provides more details on the suspension and the reasoning behind it.
