I was being rhetorical. The R in RAG is filtering augmentation data (the A) for things that might or might not be related to the query. Including everything is just a lazy form of RAG -- the rhetorical SELECT *.

>and adding that as a system/user prompt to the LLM at inference time

You understand this is all RAG is, right? RAG is any additional system to provide contextually relevant (and often more timely) supporting information to a baked model.

People sometimes project RAG out to be a specific combination of embeddings, chunking, vector DBs, etc. But that is ancillary. RAG is simply selecting the augmentation data and supplying it with the question.

Anyways, I think this thread has reached a conclusion and there really isn't much more value in it. Cheers.

The ”retrieval” refers to information retrieval, which is a technical term:

In that sense, calling ”stuff everything in the context” LLM queries a RAG system is analogous to calling a web crawler a search engine.

Sure thing.

I agree it isn't embeddings or Vector DBs.

I personally define it as not including loading all data in the context-window

Very new field and not a lot of reliable sources. Would be worth it to standardize meaning.
