Column name "Training compute cost" with unit "2023 USD" is a clear real_additive signal: cost/amount in currency. Sample values are large absolute magnitudes (1.1M to 387M USD), unbounded upper range, strictly positive, centered far from 1.0—all consistent with an extensive quantity. No multiplicative naming tokens present. This is a textbook extensive cost measure that accumulates under volume union. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
