Lesson 3 of 10 · Build a Full AI SaaS MVP
In this lesson. Ship the model path like a feature.
What you will learn
- Prompt version
- Ten evals
- Flag
Walkthrough
You will version the prompt, keep ten evals, and flag the feature. MVPs still need a gate. This is how you do not paint yourself into a corner.
Work through the ideas in order. After each point, pause and connect it to a task you already do — a document, a workflow, or a feature you own. The goal of Build a Full AI SaaS MVP is usable skill, not a pile of notes.
If something is unclear, rewrite it in your own words before you continue. Teaching the step back to yourself is the fastest way to see gaps.
Practice
Write the flag name and the ten eval ids you will have on day one.
Keep the first attempt small. A finished example you can reuse beats a perfect plan you never run.
