The Most Powerful Model on the Market Got Pulled by the Government in 3 Days. Is It Real, or a Hype Bubble?

The timing is almost too clean to be real.

On June 9, Anthropic shipped Claude Fable 5 — a "Mythos-class" model they described as more capable than anything they'd previously made generally available. Three days later, on June 12, the US Commerce Department sent a letter to CEO Dario Amodei placing Fable 5 (and its restricted sibling Mythos 5) under export controls: no access for any location outside the US, and no access for foreign persons inside it.

Anthropic couldn't filter non-US users from everyone else in real time. So they did the only thing they could: they killed the model for everyone, worldwide. Including US citizens.

If you opened a session this weekend and got "there's an issue with the selected model (claude-fable-5)... you may not have access to it" — that's not your setup. The model your session pointed at was pulled. Your projects, history, and limits are untouched; only which model answers you changed. Switch to Opus 4.8 or Sonnet and you're back.

Now the question worth actually thinking about: is this real, or is everyone inflating a bubble around a model nobody can even use right now?
