US Government directive to suspend access to Fable 5 and Mythos 5

Article excerpt

Anthropic announced it is suspending US government access to two of its AI models, Fable 5 and Mythos 5, following a directive from federal authorities. The company did not disclose the specific reasoning behind the order or which agency issued it, citing confidentiality concerns. This move affects government agencies' ability to use these particular models, though Anthropic's other AI systems remain available. The suspension underscores ongoing tensions between AI developers and regulators over model access and deployment, particularly as government entities evaluate emerging AI capabilities for official use.
