Field notes
The page says the project uses roughly 5,000 curated rows drawn from public research, MLB pitch-level data, biomechanics material, coaching content, and the author's own training logs. Its described loop fine-tunes a 27B model, runs eight benchmarks against six frontier models, then repeats; the author says this work remains in progress. It also says the dataset includes pitch-count rules for all 50 states and Washington, D.C.
