Anthropic Disables Fable 5, Mythos 5 Access in Europe

Anthropic has disabled European access to its Fable 5 and Mythos 5 AI models. The company said it believed the US government had become aware of a potential means of jailbreaking Fable 5.

European political figures aren't taking it quietly. Multiple figures have described the shutdown as a "wake-up call" about the risks of depending on American companies for critical AI technology.

The incident highlights a growing tension in transatlantic tech relations. When a single US company can flip a switch and cut off access to AI systems that European users and institutions rely on, the vulnerability becomes impossible to ignore.

The jailbreaking concern that triggered the shutdown remains vague — Anthropic offered no details on the specific vulnerability or why a blanket European access cut was the chosen response.

For Europe, the message is clear: build your own or risk getting unplugged.
