About this course

What you'll learn

By the end of this course, you'll be able to

  • Explain what Claude Fable 5.1 is and what it changes for a client, in two sentences, and what it does not change
  • Place any workload in the lineup with three questions, and say why matching model to task beats defaulting to the top model
  • Walk a client through what changes when a build moves onto the Fable tier, and which evals to run before a migration
  • Run a cross-model check against success criteria you wrote first, and recommend the model a workload calls for
  • Turn Fable 5.1's capabilities into five client workstreams, and reopen three conversations that stalled on Fable 5
  • Repeat the cross-model check before every new workload and at every model launch

Who it's for
