Federal government orders Anthropic to pull Fable 5 and Mythos 5, three days after launch
Just three days after its high-profile launch, Anthropic has been ordered by the US government to halt access to its new flagship AI models, Fable 5 and Mythos 5. The unprecedented intervention cites unspecified national security concerns, leaving the AI community speculating about the models' capabilities and the future of powerful AI development.
MY TAKE
This is a shocking development that injects a huge amount of uncertainty into the AI arms race. For developers, it's a stark reminder that cutting-edge models can be subject to regulatory whims, making platform dependency a significant risk.
