About this track

Learn to write prompts the way professionals do: clear tasks with the reasons behind them, well-chosen examples, tags that separate instructions from data, long-context layouts, step-by-step reasoning, and structured outputs your code can trust.

Then treat prompts like software - templates under version control, evaluated on categorized test sets, compared version by version - and keep them safe from injection and data leaks. Along the way you’ll duel prompts, read an eval dashboard that hides a regression, fit documents into a context window and build a ticket-triage pipeline. The guidance follows current vendor best practices from Anthropic and OpenAI.

Before you start
  • No prior prompt engineering experience needed.
  • Basic Python helps for the exercises.
  • A modern browser with JavaScript enabled.
