Nano Banana 2 Brings Reasoning and 4K to Google's Fastest Image Model
The newest Nano Banana — Gemini 3.1 Flash Image — with Pro-level smarts at Flash-tier speed.
Nano Banana 2 is the generation that closed the gap between fast and capable. It reasons about what you ask instead of pattern-matching the gist, so a detailed, multi-part prompt comes back with the pieces it actually called for, and real-world things — objects, layouts, proportions — land right rather than approximately. It holds several characters or products consistent inside a single image, and it renders up to 4K when the output is final. All of that runs at Flash speed, quicker than the Pro tier, so you get most of the quality without the wait. Start from a prompt or an upload, and reach back into your library on the next pass.

What's New in Nano Banana 2: Reasoning, Consistency, 4K
Reasoning and world knowledge
It works through a complex, multi-part prompt instead of guessing at the gist — and it draws on broad world knowledge, so real objects, layouts, and proportions come out plausible rather than almost-right. Hand it a detailed brief and more of what you specified survives into the image.
Several characters, kept consistent
Place a cast of characters or a set of products in one scene and Nano Banana 2 keeps each of them — up to five characters — looking the same, so a group illustration, a comic panel, or a product family reads as one coherent picture instead of a collage of near-misses.
Up to 4K, at Flash speed
Generate at 1K for a quick draft, then step up to 2K or 4K for finished, large-format output — and because this is the Flash tier, it turns around faster than Nano Banana Pro while still reaching the same top resolution.
Generate or edit with the newest model
Begin from a text prompt for something new, or upload an image and describe the change — both run on Gemini 3.1 Flash Image in the same panel, so you bring the newest model's smarts to creating and refining alike.

Nano Banana 2, Explained
What is Nano Banana 2?
Nano Banana 2 is Google's Gemini 3.1 Flash Image, the newest model in the Nano Banana family, released in 2026. On SupaImagine you run it in the browser to generate or edit images at 1K, 2K, or 4K, alongside other top models in one workspace.
What's new in Nano Banana 2 compared with the original Nano Banana?
It's a generation ahead: real reasoning and broader world knowledge for following detailed prompts, consistency across several characters in one image, and output up to 4K — while staying on the fast Flash tier. The original Nano Banana is still the cheaper, lighter pick for quick edits.
Should I pick Nano Banana 2 or Nano Banana Pro?
Both reach 4K. Choose Nano Banana 2 when you want speed plus reasoning and multi-character consistency for everyday high-quality work; choose Nano Banana Pro when top-end photoreal fidelity for print and large format matters more than turnaround. They sit side by side in the generator, so you can compare on the same prompt.
Does Nano Banana 2 cost more at higher resolutions?
It depends on resolution: 5 credits at 1K, 10 at 2K, and 15 at 4K. New accounts get 10 starter credits to try it, and paid plans add more — the pricing page lists current packages.
Can Nano Banana 2 render readable text inside an image?
Yes — it can place legible text in a picture, which helps for simple captions and labels. When a design is text-heavy — a poster or packaging where every word has to be exact — GPT Image 2 on SupaImagine is the more specialized pick, and it's one switch away in the same generator.
Is commercial use allowed for Nano Banana 2 output?
On a paid plan, yes — generated and edited images are cleared for commercial work like ads, listings, and client deliverables. Output made on the free starter credits is for trying the model and isn't licensed commercially.
