This tutorial shows a simple repeatable way to work with Large Language Models while focusing on evaluation.

Step 1: Define the result you want. Write down the output format, quality requirements, and any limits before you start.

Step 2: Prepare a small representative example. Test with something easy to inspect before scaling the workflow up.

Step 3: Configure the tool or prompt around evaluation. Change one important setting at a time and keep a copy of the result.

Step 4: Check performance. Verify factual claims, code, links, files, or generated media before relying on the output.

Step 5: Save the version that worked and turn it into a reusable template. Repeat the same test with a few different examples to make sure the result is consistent.
 
It may be worth simplifying step temporarily. If the simpler version works reliably, you can add the extra pieces back one at a time. It also gives you an easy point to roll back to if the next change makes things worse.
