M0 solution

M0 is a concept + browser activity, so the "solution" is a sample completed worksheet, not code.

File	What it is
model-comparison-example.md	An example of a filled-in lab worksheet, what good observations look like. Yours will differ; that's expected.

There's nothing to run in M0 (no install, no code, no key). The win is being able to explain what AI engineering is and how an LLM works, and having compared two models yourself. M1 is where you write your first line of Python.
