Gemini 2.5 Flash Image (Nano Banana)

Deprecated

The original Nano Banana. Input $0.30/1M text/image; image output $30.00/1M, which Google states as $0.039 per image (images up to 1024x1024px consume 1290 tokens). Batch $0.15 in / $0.0195 per image; Priority $0.54 in / $0.0702 per image. SHUTDOWN DATE MOVED 2026-10-07: Google's deprecations table now gives a shutdown date of March 15, 2027 (row not grey) and gemini-3.1-flash-lite-image as the recommended replacement. Until 2026-10-06 the same table gave a shutdown date of October 2, 2026 and named gemini-3.1-flash-image-preview as the replacement; that date passed with no grey marker, so the row stayed deprecated, and the preview it pointed to is itself now greyed. Google publishes shutdown dates as "the earliest possible dates on which a model might be retired"; already-shut-down models are marked with a grey row on the deprecations page.

Gemini 2.5 Flash Image (Nano Banana) by Google costs $0.3 per 1M input tokens and $30 per 1M output tokens ($7.72/1M blended). It is deprecated, shutting down 15 Mar 2027; the recommended replacement is Gemini 3.1 Flash Lite Image (Nano Banana 2 Lite).
