Anthropic-U.S. battle highlights AI power struggle

The U.S. government's move to stop Anthropic's Fable 5 and Mythos models turns a long-theoretical debate into a real-world test of who should have the power over world-changing AI. Handing the reins to companies means trusting firms with huge commercial incentives. Leaving decisions up to governments could lead to secretive high-stakes decisions with little public approval. Anthropic was given just 90 minutes to take down Fable and Mythos after Amazon raised concerns with U.S. officials about a jailbreak that could bypass Fable's guardrails and expose cybersecurity capabilities. The government imposed stringent export controls that ultimately led Anthropic to take the models offline entirely. AI policy researchers and industry critics say the U.S. is now regulating frontier models through emergency intervention rather than a clear process. "Things feel very ad hoc," said Adam Gleave, CEO at FAR.AI, an AI safety research firm, adding, "you're only as safe as the least safe model on the market."
