Got a question for people who know this stuff well. Let's say I have a generic feed forward network the size of chatGPT and structurally interconnected in the same way. Does there exist a set of weights for that network that will essentially represent the LLM that doesn't hallucinate and is similar to the perfect ai assistant we are all currently striving towards? My question is, that is it essentially a training problem?
