Nano Banana 2.1
vs Pro
A direct comparison of official per-image prices, resolution options, creative controls and the workflows where paying for Pro can make sense.
Choose 2.1 for volume and iteration. Choose Pro when maximum fidelity matters.
Nano Banana 2.1 is substantially cheaper at every documented output resolution and is built for efficient generation and conversational editing. Nano Banana Pro remains Google’s specialist choice for high-fidelity work requiring maximum factual accuracy and studio-quality control.
01 / PRICE PER IMAGE
