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.
