Amazon invested up to $33 billion into Anthropic. their researchers found a jailbreak in Fable 5. they reported it to the Commerce Department. the government shut the model down.
Amazon also builds its own AI. it's called Nova. it competes directly with Fable.
The company that just took Fable 5 offline is also the company that benefits most from Fable 5 being offline.
Now here's what the jailbreak actually was:
asking Fable 5 to read a codebase and identify software vulnerabilities.
that's it.
Anthropic says GPT-5.5 can do the same thing without any jailbreak at all.
GPT-5.5 is not under export controls.
GPT-5.5 is not shut down.
GPT-5.5 is not subject to the same standard.
Anthropic's response:
"if this standard was applied across the industry it would essentially halt all new model deployments for all frontier model providers."
they're right. and they're the only ones it was applied to.
