Lesson 1: What is AI — and what is a prompt?
A large language model is a pattern-recognition engine: an intern with perfect recall of the medical literature and zero clinical judgment. A prompt is your handoff order — and the single most powerful line in any prompt is assigning a role.
Why this matters: Ask a bare question and the model averages its answer across poets, coders and Wikipedia. Assign it a clinical role and it answers from the medical literature instead. This one line is the highest-leverage skill in prompting — and in the AMA’s latest survey, 92% of physicians said they want exactly this kind of training. It starts here.
