Project: Simplified “answer from a document” example
Make a list of 3–4 short texts. Find the text that best fits a question, put it into the request text and build a ready prompt. You do not need to connect to a real model: you check the prompt yourself.
Project steps
- I made a list of texts
- I wrote the function that finds the best text
- I built the prompt template
- I tested it with 3 questions
