The cost of training is coming down.
We have incredible open source models (especially smaller ones) like qwen 3.6-27b.
Imagine the more niche languages/frameworks getting a model rebuilt for them: zig, haskell, elixir/ash, f#, IHP, jetzig, etc.
I could imagine that there would be tremendous value in a language + framework model like: zig + jetzig that is explicitly trained on the materials and best practices for these.
Which begs the question - at what point does it make sense to make a model specifically for narrower and narrower contexts. How much faster/better could they become?
