Once I dug in to the fine-tuning APIs [1] I realized that the phrase "training the model on your docs" often doesn't make sense for the use case people are trying to solve. You provide hundreds of input examples and tell the model how it should complete those prompts. Fine-tuning has a lot of use cases, but "keeping the LLM generally grounded in the facts of my website" is not one of them.

Yes, that's what everyone says and it makes total sense to me. I'm looking for (technical, but not too technical) arguments why it is not possible. There I'm not so much interested in the "grounded in the facts of my website" point but more in the similar "take the data from my large private knowledge base into consideration" point.
In other words I don't want to restrict the knowledge the model has or the answers it gives. I want to add a considerable amount of my own knowledge. This seems not to be possible without training from scratch. The question is "Why?"
