Where did this sentence come from?

Text in an answer can have different origins.

Generation. The model produces text using learned patterns and the supplied context. It can combine familiar ideas in a new sentence.

Memorization. It sometimes reproduces training text closely. Research has measured this behaviour, including a greater tendency to reproduce material that appeared repeatedly in training.

Retrieval. The application fetches a document and supplies it to the model. The model can then quote or summarise it.

These can overlap. A system might retrieve an event page, quote one line, and generate the rest of an invitation.

The distinction matters because a sentence that looks like a quotation is not proof that anything was fetched. Look for the source, open it, and compare the wording.
