About Nano Banana 2 API

It is the Gemini-based Nano Banana line with explicit resolution selection and the same reference-image and aspect-ratio controls as other Nano Banana models on Unifically.

Nano Banana 2 1K at $0.03, Nano Banana 2 2K at $0.05, and Nano Banana 2 4K at $0.06, each per image.

Nano Banana is a single list price without separate resolution tiers. Nano Banana 2 bills by Nano Banana 2 1K, Nano Banana 2 2K, or Nano Banana 2 4K. Nano Banana Pro uses Gemini 3 Preview and the Nano Banana Pro 1K/2K price row instead of the Nano Banana 2 resolution lines.
