Google: Nano Banana (Gemini 2.5 Flash Image)
🇺🇸 Google · Nano Banana
Overview
Google: Nano Banana (Gemini 2.5 Flash Image) is a large language model API from Google, part of its Nano Banana model family. Priced at $0.300 per million input tokens and $2.50 per million output tokens, it occupies the mid-range, balancing capability against running cost. Output tokens cost about 8× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. The 33K-token context window — around 49 pages of text — comfortably handles long documents, multi-file code, or extended conversations. Beyond plain text it also accepts Image input, so it can be applied to multimodal tasks rather than text alone. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
