Can fine tuning replace the retrieval step i.e. is it possible to fine tune the model so it knows all the knowledge from my organization and we skip the retrieval step during a chat about the data
However, finetuning still cannot get rid of the hallucination problem that all the chatbot suffers from. It depends on how accurate you expect the chatbot should be. The retrieval might be considered more accurate, as it will not make up solutions, but just return irrelevant answer in the worst case.
