Ask HN: Suitable LLM models for an agent for user guides and docs?

Hi, i would like to implement an AI agent for my user guides and wiki (about 100 pages), so users can easily come in and interact with it. I expect the amount of content to increase quite a lot over time.

I would prefer it to the model to be self hosted, so I dont worry about how much APIs cost etc. My website content will be relatively small for a long time.
