Lesson notes

Season introduction: build an assistant that answers from your own documents, then measure every stage until you know why it is right and why it is wrong.

Decision rule

Build the simplest complete system. Measure it. Change one stage at a time, and keep only what clears a bar set in advance.

Ideas in this lesson

  • Measuring, not quoting
  • Retrieval
