Overview

Nano Banana 2 is Google's flagship fast image model — gemini-3.1-flash-image-preview under the hood — with the highest LM Arena Elo score (1263) of any Gemini image model as of May 2026. It produces realistic, high-fidelity images with strong prompt adherence and natural typography, all in a single low-latency request.

It is Google's direct-to-developer image model accessed via the Gemini Developer API. CallMissed routes requests straight to Google with no markup — you pay exactly Google's standard 1K-tier rate of $0.067 per image, just as if you were calling the Gemini API yourself.

The model is multimodal: it accepts both text prompts and reference images, allowing for image-to-image editing, style transfer, and consistent character generation across multiple outputs. Default output is 1024×1024 — 4K resolution requests follow Google's tiered pricing.
