Why retrieve

Learn in five minutes

• A model does not contain your private notes.
• Retrieval finds passages and puts them in the call.
• The 2020 RAG paper is the usual citation for that pattern.
• If retrieval misses, a fluent answer is still ungrounded.
• Say which passage you used.

Two systems can share a model and differ only in the notes they retrieve. The notes are the part you control.

The capstone answers only from notes you are allowed to use.

Config

• Write the goal in one sentence.
• Name the input and the allowed output.
