The original Nano Banana model was impressive enough, but Google is bragging about Nano Banana 2 as if the original model was nothing but cardboard cutouts. It is faster and more logical thanks to its ability to plan its composition before rendering it.

How do you use it? Nano Banana 2 has already rolled out behind the scenes, so if you create an image in Gemini now that's what it will use. Just tap the Create Image and type in your prompt. You'll see that a number of preset styles like Cyborg or Cinematic are available.

Google implies that Nano Banana 2 can essentially engineer reality from prompts, so I decided to peel back the hype and see how potent the model really is.

1. Clarity is key

Here's the first prompt I used:

A macro photograph capturing a clear glass sphere balanced perfectly atop the spout of a ceramic teapot. Inside the sphere, intricate, tiny silver letters spell out the phrase, "CLARITY IS KEY."

This prompt is a triple-threat test designed to humble any model still struggling with physical logic, material properties, and basic spelling. Nano Banana 2’s reasoning engine must first determine the complex physics of nesting tiny text inside a sphere, and then calculate how that text should warp and refract.

The resulting image showcases its flawless typography; the tiny silver letters are legible and subtly distorted by the sphere’s curvature, revealing high-fidelity texture.

2. Airship animals

Here's the prompt:

"A cinematic shot of a steampunk pirate ship sailing through a sea of clouds at sunset. The ship is made of polished brass, copper, and dark wood and has a crew of anthropomorphic animals."

When a model is asked to render a complex scene, there's a risk of visual chaos or subject drift. Nano Banana 2 navigates the issue well, defining and maintaining multiple subjects, and the detailed steampunk ship shows logical engineering, all bathed in cinematic golden-hour lighting that reflects off the complex brass and wood surfaces.
