Building AI Apps with LLMs

What you’ll learn

• Understand the model

  Reason about tokens, context windows, and sampling instead of treating the model as a black box.

• Get structured output

  Make a model return data your program can rely on, and validate it before you use it.

• Wire up tool calling

  Let the model call your functions, and keep the loop bounded and observable.

• Ship it affordably

  Stream responses, cache what repeats, and keep latency and spend under control.
