Definitely a need, kudos for tackling it!

I’d still look into fine tuning. One of the main issues I’m struggling with is that even reasonably simple drivers often need to be aware of Application Notes etc that would single handedly blow past any context window. So giving the model a fighting chance by narrowing the space might be worthwhile here. Top 20 vendors datasheets/docs, handpicked sites and forums etc.

we are talking to a some of the larger vendors about getting first-party support for documentation. once we scale up a bit I think it could make sense to have multiple fine tuned models based on the docs they provide (or we crawl the web for public ones, at minimum)
