Gaps in this history

Exact date of the 2025 price cut not documented (bounded 2025-01-29 to 2025-02-01). Batch prices ($0.55/$2.20) appear only on platform docs captures from 2025-12-11, after the model's 2025-10-27 shutdown; earlier pages list o1-mini in tables with no batch column, so no batch rate is recorded.
