Nano Banana is Google's image model embedded in Gemini, purpose-built for fast generation with in-image text accuracy. Through RunAPI, all Nano Banana variants share a single key.
A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.
Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.
Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.
Nano Banana is optimized for text accuracy — it reliably renders short to medium-length text like headlines, labels, and captions within generated images.
Nano Banana maintains consistent character appearance across multiple subjects in the same image — faces, clothing, and proportions stay coherent.
The base variant is fast. The pro variant takes 10–20 seconds but outputs up to 4K resolution.
Pro is built on Gemini 3 Pro and outputs up to 4K with the best text rendering. The standard variant is optimized for faster generation at 1K.
Yes — Nano Banana 2 Lite and the edit variant accept source images and apply prompt-driven modifications while preserving the original composition.
Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
