Checked 2026-10-31

Nano Banana 2.1 is Google's image generation and editing model in the Gemini API, with the official model ID gemini-nano-banana-2.1. It takes text, image, video and PDF input and returns image and text. Google lists an input limit of 131,072 tokens and an output limit of 32,768 tokens. On the Gemini API pricing page the standard tier is $1.50 per million input tokens, $7.50 per million text and thinking output tokens and $30.00 per million image output tokens. Per image it lists $0.0336 at 1K, $0.0504 at 2K and $0.113 at 4K, with batch at half that. It is not on the free tier. It supports image generation, search grounding, thinking and the Batch API. It does not support function calling, structured outputs, context caching, code execution or the Live API, so build tool-driven flows around it, not inside it. Output is 1K, 2K or 4K, takes up to 14 reference images, and every image carries a SynthID watermark. Google's docs describe it as available in the Gemini API and link to Google AI Studio; we did not find the Gemini app or Vertex AI named for it. We have not run it ourselves for this note.
