Also, another library to check out is GPT Index (https://github.com/jerryjliu/gpt_index) which takes a more "data structure" approach (and actually uses langchain for some stuff under the hood).
Thank you for the link. I have a project with plenty of structured data from which I create summaries and short articles. Currently I'm generating prompts with context inside the prompt. GPT Index seems to pretty well fitted to that usecase
