Module 1 challenge

Build a Mental Model of an LLM

You have the pieces. Assemble one path that turns raw text into a generated next token. When it works, we change one constraint and ask you to diagnose the failure like an engineer.

Your job

Use every service in the left palette. Connect them into one left-to-right path so each step feeds the next. Do not leave unused services or dead ends.
