It does. Anthropic mentions (https://www.anthropic.com/news/fable-mythos-access) they consider jailbreaks that "provide no Mythos-specific uplift" to be minor findings; perhaps they couldn't agree on what kinds of capabilities were unlocked by the jailbreak Amazon found.
Very questionable and tone deaf response from Anthropic. Irrelevant whether it’s specific to Mythos or Haiku. Dario seems to be looking for an exit.
