How to read this report
- 01Each row is a dated verified model record; later records can preserve subsequent price or availability changes.
- 02Prices are shown exactly as disclosed per million tokens and are not adjusted for caching, batching, or enterprise discounts.
- 03The chart is an observation history, not a claim that unchanged prices persisted between observations.
