100-word summary
ElevenLabs just integrated Claude 3.7 Sonnet into its voice AI platform, but there's a catch: Anthropic has already retired the model. The integration lets voice agents handle longer conversations and follow instructions more precisely, useful for tutoring bots that field follow-up questions or support agents remembering earlier exchanges. ElevenLabs promotes faster prototyping with templates and configurable prompts, but companies building on 3.7 will need to migrate to newer Sonnet or Opus versions soon. The timing is awkward: Anthropic is pushing memory features and improved app integrations this month, yet ElevenLabs is betting on yesterday's model.
