Detailed syllabus

  • What changes between a successful demonstration and high-volume use
  • Judge a prompt on its worst output, not its best
  • The three most frequent causes of drift

  • Impose a format: mandatory fields, closed lists, length
  • Explicitly plan for the case where the model cannot answer
  • Produce a result another tool can reuse directly

  • Build a representative sample of your real cases
  • Compare two versions of a prompt on the same sample
  • Set the acceptable error rate according to what is at stake

  • Document a prompt for someone who did not write it
  • Organise a shared library within a team
  • Spot drift after a few weeks of use

The day's reversal

A demonstration prompt is judged on its best output. A production prompt is judged on its worst output.

The whole day follows from this reversal. It is what sets it apart from an introduction.

Learning objectives

  • Structure a prompt whose result is reproducible
  • Constrain an output format that is usable without rework
  • Build a set of test cases, edge cases included
  • Document and share a prompt across a team

Who it is for

  • People already comfortable with a conversational assistant
  • AI leads of a department or a team
  • Freelancers producing content at a regular volume

Prerequisites

  • Regular use of an AI assistant for at least a few weeks

Teaching methods and materials

  • Alternating demonstrations and individual workshops
  • Comparison of two versions of a prompt on the same set of cases
  • Prompt library template provided and filled in during the session

Assessment methods

  • Placement questionnaire at the start of the day
