Pricing Details
GoogleImage generation model (Nano Banana 2 Lite) and the cheapest durable way to leave Imagen 4, though no Google migration notice names it. The stored output rate is the IMAGE rate of $30.00/1M, exactly half Gemini 3.1 Flash Image; text and thinking output bills at $1.50/1M. Limited to 1K output (2K and 4K unsupported). At 1,120 tokens that is $0.0336 per image standard and $0.0168 batched, both figures printed in Google's own pricing footnote. The batched rate undercuts Imagen 4 Fast's flat $0.02, so a migration off the cheapest Imagen tier can lower the bill rather than raise it. Gemini 2.5 Flash Image batched ($0.0195) also undercuts Imagen 4 Fast and is the target named on three of five Google pages, but it shuts down 2026-10-02, so this model is the only Google image model that is both cheaper than Imagen 4 Fast and free of an announced end date. Note that standard Flash Lite Image and batched Flash Image both land on $0.0336, turning that choice into a straight trade between a lighter model now and a better model on a 24h delay for identical money. Batch input $0.125/1M. No free tier. Thinking is on by default and billed at the text rate, so treat per-image figures as a floor. GA 2026-06-30, no announced shutdown. Estimated tokens.
