Capabilities

What's new in Nano Banana 2.

Pro quality at Flash speed

Built on Gemini 3.1 Flash, it brings Nano Banana Pro's reasoning, world knowledge, and visual fidelity into a faster, cheaper package, and it replaced the original Nano Banana.

Faster and cheaper than Pro

It generates in roughly 4 to 6 seconds at about half the per-image cost of Nano Banana Pro, which suits high-volume and iterative work.

Up to 4K output

It supports resolutions from 512px up to 4096px across 14 aspect ratios, covering everything from social posts to print.

Search grounding and world knowledge

It pulls from Gemini's knowledge base and real-time web search to render specific subjects accurately, and it excels at infographics, notes-to-diagrams, and data visualizations.

Strong multi-subject consistency

It keeps multiple characters and objects consistent across a series of images, alongside accurate multilingual text rendering and translation.

Flexible reasoning and provenance

It offers minimal or high reasoning levels, and every output carries an invisible SynthID watermark plus C2PA Content Credentials.

Use cases

What teams build with Nano Banana 2.

The default for new builds

Near-Pro output at half the price and roughly twice the speed, the tier most teams standardize on for generation and editing.

Generation + editing in one

One model covers text-to-image and conversational editing, so a single integration handles the full image workflow.

World knowledge on tap

Search grounding and multimodal knowledge keep real subjects, products, landmarks, people, accurate instead of approximate.

Multi-subject consistency

Strong identity holding across subjects and edits, up to 4K when the deliverable demands it.

Reviews

Speeds up our ad creative iteration

The API integrates directly into my existing pipeline, so I can generate and iterate on image variations for Meta ads without jumping between tools. We can go from concept to a testable ad in the same day instead of spreading it across a week.

Ethan M. July 2026 G2

Fast, reliable, easy to integrate

Image generation requests are processed quickly, and the results are consistently high quality. Customer support has also been responsive whenever I had questions. It has saved me a lot of development time.

Nana Arianto July 2026 Trustpilot

Seamless integrations, effortless setup

Generating ad creatives for Facebook and Google ads is more streamlined now since we use APIFRAME to manage the workflow, which used to require a lot of time with official APIs. The initial setup was very easy, just a matter of using curl.
