No changelog entry or announcement dates explicit caching for 2.5 Flash Preview; the date is bounded by the captures of 2025-05-10 01:38 UTC ('Coming soon!') and 2025-05-11 21:02 UTC (priced). The row was dropped from the pricing page on 2025-06-17.

    Context caching was 'Coming soon!' at launch; the cached rate arrived later (see the 2025-05-11 addition). The 2025-05-21 page, a day after 05-20 was released, still had a single 'Gemini 2.5 Flash Preview' row at the same price.

Gaps in this history

What gemini-2.5-flash-preview-05-20 was billed from 2025-06-17 until its 2025-11-18 shutdown is undocumented: the pricing page dropped the preview row on 2025-06-17. The cached rate's start is only bounded (2025-05-10 to 2025-05-11). No batch prices (the row was gone before batch mode launched on 2025-07-07).
