How to choose between Nano Banana Pro, 2 and 2 Lite
Start with the job, not the model
Use Lite to find a prompt that works without spending much. Move the final prompt to Nano Banana 2 for a bigger file, or to Pro for the image a customer will study closely.
Size
Lite makes 1K images only. Nano Banana 2 goes from 512px to 4K and Pro from 1K to 4K. Bigger sizes cost more, and your agent works out the exact price for the size you ask for.
Editing
All three edit from reference images. Give your agent a product photo and ask for a new background, light or season, or combine several images into one scene.
| If you need | Choose | Today's price |
|---|---|---|
| A final product photo or ad at 4K | Nano Banana Pro | $0.195 per image |
| A batch of social images in several formats | Nano Banana 2 | $0.065 per image |
| An edit of a photo you already have | Nano Banana 2 | $0.065 per image |
| Ten quick drafts to find the prompt | Nano Banana 2 Lite | $0.052 per image |
| Motion from the finished image | Kling or Seedance, on our video page |
Quick picks: Nano Banana 2 Lite for drafts, Nano Banana 2 for everyday images and edits, and Nano Banana Pro for the final image.
Nano Banana API or MCP: which should you use?
The Nano Banana API is for developers: you create a Gemini API key, write code and pay Google directly. Most Nano Banana MCP servers we found are community projects that also want that key stored on your machine, and Google's own open-source genmedia servers are marked as not an officially supported product and run in your own Google Cloud project. Through Agensi you connect your agent once and sign in, with no key to store, and Nano Banana sits next to GPT Image, video, voice and data tools on one balance.
| What you get | Official MCP per brand | Own API key or community server | Agensi |
|---|---|---|---|
| Accounts | One per brand | One per brand | One |
| API keys | Per brand, or a sign-in | Per brand, kept by you | None |
| Payment | A plan or credits per brand | Per brand | One balance, per use |
| Spending control | Varies | Up to you | Limits per use, day and month, or ask first |
| Several sources in one answer | Connect several servers | Several servers and keys | One connection |
| Skills for the whole job | No | No | Yes, from the marketplace |
When another way is the better choice. If you call Nano Banana thousands of times a month from your own app, use Google's Gemini API with your own key: you get Google's quotas, settings and billing directly. Agensi is built for using Nano Banana from an AI agent, next to other tools, without managing keys.
