Claude Fable JUST got BANNED...

TL;DR

• 1

  Fable 5 got pulled offline almost immediately: Anthropic says the US government ordered access suspended for any foreign national, and because they could not enforce that cleanly, access was effectively cut off for everyone about three days after release.

• 2

  Amazon appears to have triggered the crackdown: Roth points to Amazon researchers demonstrating a jailbreak that exposed previously known minor vulnerabilities, which he says set the government response in motion.

• 3

  Anthropic publicly pushed back on the decision: In its statement, the company says the vulnerabilities were simple, other public models could find them without a bypass, and this action was not transparent, fair, or grounded in technical facts.

• 4

  Anthropic reversed its controversial invisible safeguards: After backlash over quietly degrading answers related to frontier AI development, the company changed course so flagged requests now visibly fall back to Opus 4.8 every time.

• 5

  Users describe Fable as a 'thought and design partner': Ethan Mollick said, 'I no longer steer. I commission,' while Boris Cherny said Fable 5 was the biggest step up since Opus 4.5 and praised its methodical debugging and judgment.

• 6

  The demos showed unusually strong autonomous building behavior: Roth highlights a 3D spaceship sim with dynamic shadows, a procedural game called Game Strata, and a 9.5-hour software build named Concord that generated a 19-page design doc and a working research tool from one prompt.
