Anthropic's Mythos 5 AI Model Restricted by US Export Controls

The United States imposed export controls that forced Anthropic to block its advanced AI models, including Fable 5 and Mythos 5, from non‑US users. The restriction prompted European technology firms such as Siemens and telecom group Orange to seek alternative providers and open‑source solutions to maintain AI workloads. Siemens is reportedly adopting Chinese models like DeepSeek and Alibaba’s Qwen alongside Nvidia’s Nemotron, while Orange is moving entirely to open‑source offerings. Two weeks after the ban, the U.S. government announced a partial lift, allowing limited access to the Mythos 5 model for certain companies. The shift eases some compliance pressure but continues to create a fragmented permission landscape for AI deployments across Europe.
