Strategies to feed GPT4 bot with product database to maintain context

the titles says it all :slight_smile:
what would you recommend as a strategy to use gpt4 for a “sales” recommendation bot

  • feed it with small chunks of the product data based on a pre-processing (keyword) of user request
  • pre-process thanks to a fine tuned davinci model and use GPT4 just for the conversational side?
  • embeddings search pre-processing?

in general anyone with experience in this ?
