Crypto investors and builders say the censorship of Anthropic's Fable 5 proves their long-running argument: that AI should run on decentralized networks no company or government can switch off.
The model shipped with guardrails so broad that many users complained, by Anthropic's own account, and would quietly degrade its answers when asked to help train other AI. Then on June 12 the US government forced Anthropic to disable Fable 5 and its more powerful sibling Mythos 5 for every user, after an export control directive barred access by any foreign national, the company said in a statement. The order covered foreign nationals inside and outside the US, including Anthropic's own employees, and left other models such as Claude Opus 4.8 untouched.
For a corner of crypto that has spent years building AI on blockchains, the takedown was a live demonstration of its pitch.
"Their access to AI is at will," said Jake Brukhman, founder and chief executive of CoinFund, one of the earliest US crypto investment firms, on a Defiant panel. "It's at the pleasure of big private companies like Anthropic and OpenAI ... and the whim of the government." When the order hit one company, he noted, the effect was a near-global shutdown.
