Not sure about how the code in this project works. But the way I see it, an LLM+chat is a great interface for information. If you then connect it to a db with the knowledge/articles you need, then you get a great way to navigate it, without needing the model to memorize all the info
I agree with the OP; this technology does not seem an appropriate fit for survival equipment. By definition survival scenarios can be life and death. Even one "You're absolutely right!" level mistake from an LLM could give a user bad information, leading to John Doe eating a mushroom he really should not have eaten.
I think that if I were to build this I might skip the LLM and just setup a nice interface to the source files using qmd style search. [0]
That way the tiny model isn't acting as a potentially incorrect interpreter but you still get semantic search to help you find the right documents quickly.
I suppose there is something to be said for a good summarization, I just worry that these tiny models aren't really GOOD summarizers.
