Nano Banana 2
Fast, high-efficiency AI image generation powered by Gemini 3.1 Flash
Nano Banana 2 is Google's high-efficiency image generation model, officially named Gemini 3.1 Flash Image. It brings much of Nano Banana Pro's quality to a faster, more affordable architecture — making it the go-to choice for everyday image creation, rapid iteration, and high-volume workflows. On Keyo Studio, Nano Banana 2 generates high-quality images in seconds, at up to 4K resolution, with the reasoning of Gemini 3.1 behind every result.
What is Nano Banana 2?
Nano Banana 2 is built on Gemini 3.1 Flash Image, the speed-optimized member of Google DeepMind's Nano Banana family. Released in February 2026, it distills the multimodal reasoning of the Pro model into a faster architecture — Google describes it as delivering around 95% of Nano Banana Pro's capabilities at a significantly lower cost. In practice, Nano Banana 2 is the recommended default for most projects: fast enough for rapid iteration, strong enough for professional product and social content, and far more economical when you need many images.
Built for speed and volume
Where Nano Banana Pro "thinks harder" about complex scenes, Nano Banana 2 thinks fast enough for almost everything. It generates standard images in just a few seconds — several times faster than Pro — which makes a real difference when you're producing dozens of variations, running A/B tests, or iterating on a concept. If Pro is a professional DSLR, Nano Banana 2 is a high-end smartphone camera: both produce excellent results, but Nano Banana 2 is built for the everyday, high-throughput work.
Resolutions and aspect ratios
Nano Banana 2 supports a full range of output resolutions — from 0.5K for quick drafts, through 1K (default) and 2K, up to 4K for high-fidelity final assets. It also handles a wide variety of aspect ratios, including square, portrait, landscape, and widescreen formats, with improved aspect-ratio adherence over previous models. This flexibility lets you draft cheaply at low resolution and render the final version at 4K only when the composition is right.
Search grounding and text rendering
Like the Pro model, Nano Banana 2 supports Image Search Grounding — combining text and image search results to inform generation with real-time web data. It also features improved multilingual text rendering, producing clearer, more accurate text inside images across languages. This makes it a strong choice for social graphics, product listings, and marketing assets that need legible text and real-world accuracy.
When to choose Nano Banana 2 vs Pro
Choose Nano Banana 2 for everyday production: rapid product mockups, listing images, social content, thumbnails, and any project where you need speed, volume, and value. Choose Nano Banana Pro when the stakes are highest — hero images, print-quality assets, text-heavy poster designs, and complex multi-element compositions that demand maximum fidelity. A common workflow is to default to Nano Banana 2 for most tasks and reserve Pro for the critical 10–20%.
Pricing on Keyo Studio
On Keyo Studio, Nano Banana 2 is priced by resolution: 2 credits for 1K, 3 credits for 2K, and 4 credits for 4K. Its low cost makes it ideal for high-volume work — draft freely at lower resolutions, then render your final version at 4K.
Content authenticity
Every image generated with Nano Banana 2 includes an invisible SynthID watermark embedded by Google in the pixel data. It's undetectable to the eye but verifiable through Google's tools, providing transparent provenance for AI-generated content.
Frequently asked questions
What is Nano Banana 2?

Nano Banana 2 is priced by resolution: 2 credits for 1K, 3 credits for 2K, and 4 credits for 4K. Its low cost makes it ideal for high-volume work — draft freely at lower resolutions, then render your final version at 4K.
What's the difference between Nano Banana 2 and Nano Banana Pro?
Nano Banana 2 is the cheaper, faster sibling built for high-volume work and quick iterations, while Nano Banana Pro is the high-quality lane for maximum fidelity and complex scenes. Choose Nano Banana 2 for speed and volume, Pro for final quality.
Does Nano Banana 2 have a watermark?
Yes. Every image generated with Nano Banana 2 includes an invisible SynthID watermark embedded by Google in the pixel data. It's undetectable to the eye but verifiable through Google's tools, providing transparent provenance for AI-generated content.
Is Nano Banana 2 good at text in images?
Yes. Nano Banana 2 renders accurate, legible text for mockups and marketing, and can even translate and localize text within an image, inheriting strong text capabilities from the Nano Banana Pro family at faster speed.
What can I use Nano Banana 2 for?
Nano Banana 2 is ideal for high-volume, fast-turnaround image work — rapid iterations, marketing mockups, infographics, and everyday generation where speed and low cost matter more than absolute maximum fidelity.
