What is Nano Banana Pro?
Nano Banana Pro is Google DeepMind’s image generation and editing model, officially Gemini 3 Pro Image (model id gemini-3-pro-image; preview November 2025, generally available since May 2026). Spicymayo accesses it through fal and provides the browser workspace, account, image history, and subscription credits around it.
You do not need to configure an API key to use Spicymayo. Image generation requires a signed-in account and available credits.

Is Nano Banana Pro the same as Nano Banana 2.1, Nano Banana 2.5 or the spicy-mayo model?
No — and the difference matters if you arrived here from a “Nano Banana 2.5” or “spicy mayo” search. Nano Banana Pro is Google's premium image model (Gemini 3 Pro Image), and it is what this page and our studio run: 2K or 4K output, seven aspect ratios, one reference image, 50 or 100 credits.
Status as of : Google released Nano Banana 2.1 (model id gemini-nano-banana-2.1) on 6 October 2026. Whether the Arena model codenamed spicy-mayo shipped as Nano Banana 2.1 is reported by trackers and not confirmed by Google or Arena. No model named "Nano Banana 2.5" has been released.
“spicy-mayo” is the codename of an anonymous model tested in Arena's blind battles from 9 September 2026 and nicknamed “Nano Banana 2.5” by testers; Google never released a model under that name. On 6 October 2026 Google released Nano Banana 2.1 (gemini-nano-banana-2.1), the lower-cost counterpart to Pro, which trackers report is the spicy-mayo model under its production name. Nano Banana 2.1 is also selectable in Spicy Mayo (30–60 credits, up to four reference photos); Pro remains the pick for the most demanding 4K and typography work.

Four ways to edit a reference image
Restyle the photograph
Try an editorial film look or a different color treatment. Name the visual qualities you want, such as warm tones or softer contrast.
Change the lighting
Specify the direction, softness, and color of the light. Keep the subject and composition in the instructions if they should stay consistent.
Create a product-style shot
Ask for an uncluttered background and studio lighting. Check labels, shapes, and product details carefully before using the output.
Use Nano Banana Pro in your browser
Spicy Mayo is an independent studio built around released models such as Nano Banana Pro. Choose the AI image generator to start from text, or the AI image editor to work with a photo. You can also start with a prompt for a background change or a video thumbnail. The studio uses the Pro model and is not affiliated with Google.

Choose output size before you generate
A 2K image uses 50 credits; a 4K image uses 100. Start with 2K while exploring a composition, and choose 4K when you want the higher-resolution output. Resolution changes image dimensions; it does not guarantee a perfect edit.
Spicymayo Pro includes 2,200 credits for US$29.99 per month, without rollover. See pricing and subscription details.
