If I understand you want to use your own corpus of information/data and have the AI look to that information when constructing an answer/completion? If yes, this is a use case for embeddings with semantic search. Meaning you can create embeddings (vector representations of your white papers, articles, etc.) and then when you construct the AI prompt you do a search against your data and the results of that search are used for the prompt to the Completion request. Here's some more details from Microsoft and OpenAI's docs on embeddings. I think this is what might help you "import" your own corpus of information.
