Anthropic’s powerful AI models, Mythos 5 and Fable 5, have been offline for two weeks due to a White House export control order citing security concerns. The company is in high-intensity negotiations with the Trump administration, but no resolution is in sight. The lack of progress is causing uncertainty for the US AI industry, and the situation is becoming increasingly dire. The impasse may be due to the lack of a clear framework for applying export controls to AI systems. Why it matters: the outcome of this standoff could have significant implications for the future of AI development and regulation in the US.
