Favourable model size / score regionObserved Pareto frontier

Green uses cohort medians, not a universal quality threshold. Frontier points have no measured alternative with both smaller model size and higher score. Lines connect observed points; they do not predict intermediate models. Uncertainty is not included in frontier membership.

2 compatible measurements. Parameter counts come from the architecture instantiated from each pinned model configuration; no weights are loaded for this count. Click a point to inspect its evidence.
