Amazon's Jassy reportedly flagged Fable jailbreak to White House before crackdown

According to Reuters and The Information, Amazon CEO Andy Jassy personally raised concerns about a Fable jailbreak directly with the White House, an intervention that preceded — and reportedly helped trigger — the US directive ordering Anthropic to block foreign nationals from using Claude Fable 5 and Mythos 5. The revelation reframes the suspension from a purely regulatory event into a story about a cloud partner acting as a gatekeeper against the very model vendor it has invested billions in.

The mechanics matter because Amazon is both Anthropic's largest investor and the host of Fable 5 on Amazon Bedrock, where it reached general availability on June 9. Having a strategic partner escalate a safety concern to government before resolving it with the vendor directly struck many observers as a breach of trust. The Washington Post reported the broader precedent: that export-control authority can now be used to intervene in already-deployed, commercially available AI models.

The fallout was immediate on Reddit, where r/Anthropic's thread 'Anthropic or other AI companies will never trust Amazon again' hit 1,034 upvotes, accusing AWS of going to Trump before Anthropic. The episode raises hard questions about the cloud-provider relationship as frontier labs increasingly depend on hyperscalers for distribution while competing with them on models and agents. Watch whether Anthropic diversifies its cloud footprint or renegotiates terms with Amazon in the aftermath.
