I took note of something recently from the Library Innovation Lab at Harvard Law School: WARC-GPT: An Open-Source Tool for Exploring Web Archives Using AI. It takes the contents of WARC files and feeds them into a Retrieval Augmented Generation tool. Been meaning to play with it as a way to enhance FOLIO's docmuentation search, but haven gotten around to it.

Not a war story, perhaps, but a WARC story.  ;-)

Thus, if we were create our own model, then we can trust the results. Right? Well, almost. The things of ChatGPT are "large language models" and the creation of such things are very expensive. They require more content than we have, more computing horsepower than we are willing to buy, and more computing expertise than we are willing to hire. On the other hand there is a process called "fine-tuning", where one's own content is used to supplement an existing large-language model, and in the end the model knows about one's own content. I plan to experiment with this process; I plan to fine-tune an existing large-language model and experiment with it use.

Next, given a query, the index is searched for matching documents. Third, the matching documents are given as input to the large-language model, and the model uses the documents to structure the result -- a simple sentence, a paragraph, a few paragraphs, an outline, or some sort of structured data (CSV, JSON, etc.). In any case, only the content given to the model is used for analysis, and the model's primary purpose is to structure the result. Compared to fine-tuning, RAG is computationally dirt cheap. Like fine-tuning, I plan to experiment with RAG.
