Last Friday, the U.S. Commerce Department sent a letter to Anthropic. By that evening, Fable 5 and Mythos 5 were gone. Not deprecated. Not throttled. Gone. API calls returned 404s. Live sessions errored out mid-conversation. Production applications that depended on those models simply stopped working.
Three days after launch. No warning. No migration window.
And honestly? We got lucky this time. Fable 5 was only available for three days. Nobody had time to build real production dependencies on it. Imagine this happening to a model you've been using for six months. A model your entire product depends on. That's the scenario you should be planning for.
I would like to ask you something. If your database vendor could be forced to shut down your primary database with a single government letter, would you run it without a failover? Of course not. But that's exactly what most teams are doing with their AI provider.
