benchmark — A standard public test set for comparing AI models — the shared scoreboards behind every "model X beats model Y" claim.
LoRA — A cheap way to fine-tune a model by training a small add-on layer instead of changing all of the model's weights.
eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
Why it matters
Schema compliance decides whether a small model can be wired into a downstream system at all. This is a cheap, reproducible RL run that measurably closes part of that gap on a 350M model.
