Gemini 2.5 Flash cache-read price history tracks cache read list pricing for gemini-2.5-flash. It publishes 1 editorially verified episode while preserving the broader machine timeline as a separate evidence layer.
Identity and scope
The stable API model ID is gemini-2.5-flash. The tracked component is standard paid-tier context-cache reads for text, image and video tokens, not audio caching, cache storage, Batch, Flex or Priority service.
Editorially verified change
The standard context-cache read rate fell 60% while the model ID stayed stable. Cost comparisons that retain the earlier $0.075 rate overstate the cached-input portion of later Gemini 2.5 Flash workloads.

How to use this history
Use the verified row when reconstructing a dated standard-list-price estimate. Use the machine timeline to audit extraction and locate captures, not to infer billing scope or a precise effective timestamp. Recheck the provider’s current documentation before making a live purchasing or architecture decision.
