This is a very good explanation for RAG systems. But the ChatGPT work in combinations of RAG systems and Generator Systems. GPTs are decoder only type of Transformer models which are pre trained on large amounts of data which allows it to predict the next words based on the Semantic Similarity and Distances between the vectors. This allows for them to generate text/images. In this case, because the query was just asking the LLM to give a response instead of generating some text, you using a BERT was sufficient, in the other case you will need to use the GPT to generate the text as a response.

The discussion really drifted from the actual system design focus. If the LLM is a black box, there's no need to talk about how it generates responses. The real challenge is how to build the system around it — managing context windows, chat threads, limiting to 50 chats per user, syncing across devices, storing chat history efficiently, and keeping latency low. That’s what a “design ChatGPT” question is actually testing.

This is a really good attempt, but it goes into rag like system in a weird half baked way. In my opinion, it should start at the core problem of treating the transformer based text to text generator model as a black box and start with discussions about its input and output. And the challenges regarding scaling on both sides. RAG should come much later, as probably the last functional layer, to specifically solve the problem of bringing in certain world knowledge that the black box model is unaware of. But the systems design should start by first solving the design for the world knowledge that the model already has.
