Nano Banana AI Image Generator
Google DeepMind's Gemini 2.5 Flash Image — the fast, affordable everyday image model for text-to-image and natural-language editing.
Features of Nano Banana
Natural-Language Image Editing
Just describe the change. Remove a passerby, swap an outfit, relight the scene, or fix a small detail — Nano Banana preserves the rest of the photo while applying the edit you asked for.
Multi-Image Fusion
Upload up to three reference images to blend subjects, keep a character or product consistent across scenes, or combine a style image with your subject. Each reference adds context the model reasons over — not just a style filter.
Built for Speed and Volume
Nano Banana sits on the Flash tier for a reason: single-digit second generation, low cost, and generous throughput. It's the right default when you need dozens of variations or a quick first draft.
11 Aspect Ratios Out of the Box
Go from square social posts to cinematic 21:9 hero banners with one parameter. Pick a ratio, or leave it on Auto to let the model choose based on your prompt.
Safe by Default with SynthID
Every Nano Banana output carries an invisible SynthID watermark signed by Google DeepMind. The watermark doesn't affect image quality but makes provenance verifiable — important for publishers, marketplaces, and compliance-sensitive teams.
Text-to-Image and Image-to-Image in One Model
The same model handles prompt-only generation and multi-reference editing. Start from nothing, start from a product photo, or start from a sketch — the pipeline and pricing stay the same.

Frequently Asked Questions
Find answers to common questions about this model
Nano Banana is Google DeepMind's public nickname for the Gemini 2.5 Flash Image model. The name started as an internal codename during anonymous testing on LMArena in August 2025 — it went viral, and Google kept it as the official product name. It launched in Preview on August 26, 2025 and became generally available on October 2, 2025.
They are two different Google models. Nano Banana (this page) is based on Gemini 2.5 Flash Image — optimized for speed and low cost. Nano Banana Pro is based on Gemini 3 Pro Image, released in November 2025 — optimized for 4K output, multilingual text rendering, and strict multi-character consistency. Use the standard model for everyday volume work; upgrade to Pro when you need poster-grade output or precise typography.
Our platform accepts up to 10 reference files per request (JPEG, PNG, or WebP, 10 MB each). Google's official guidance is that three references or fewer produce the best fidelity — beyond that, the model has to compromise between inputs. For subject consistency, keep references tight and closely related.
Ten official ratios: 1:1, 9:16, 16:9, 3:4, 4:3, 3:2, 2:3, 5:4, 4:5, and 21:9. An Auto option is also available — the model picks the ratio that best fits your prompt. All ratios arrive at native resolution, no cropping.
Nano Banana runs on the Flash tier, so most images come back in under 10 seconds. Pricing is a flat 3 credits per image for both text-to-image and image-to-image — there's no resolution surcharge, unlike Pro.
Yes. Images generated with your account can be used for commercial purposes under our terms of service. All outputs include Google's SynthID invisible watermark, which makes AI provenance verifiable without affecting image quality. Many platforms and publishers now require or prefer watermarked AI content.
Pick Nano Banana when you need speed, volume, cheap iterations, everyday photo edits, or quick first drafts. Pick Pro when the final asset needs crisp typography (posters, thumbnails with text), 4K resolution, or strict multi-character consistency across many frames.
Yes. The same model powers text-to-image and image-to-image — no separate editor. Send a prompt alone to generate from scratch, or send a prompt plus reference images to edit, extend, or blend. The pricing is identical for either mode.
