A selection-based training loop
A model generates candidate solutions, a rule or reviewer selects useful examples, and the selected outputs become training data. STaR studies a reasoning-bootstrapping approach of this kind. The important design question is what qualifies an attempt for selection and what information the policy had when producing it.
A correct result may have the wrong explanation
A final-answer check can retain a lucky answer with invalid reasoning. A strict process check can reject useful unconventional work. Review what the selector actually verifies and preserve the distinction between an answer key, a proof check, and a judgment of explanatory quality.
Selection can narrow the distribution
Easy tasks and familiar strategies may contribute most accepted samples. Track which task families survive, how many attempts they consume, and whether difficult but important failure modes disappear from the training mix. Acceptance rate is a property of the generator and selector together.
Account for the full compute bill
Report sampling cost, filtering cost, training cost, and matched test-time evaluation. A new checkpoint should be compared at the same inference budget as its base. Extra attempts used to manufacture the dataset remain part of the intervention even when the resulting student is inexpensive to serve.
