Google’s new Nano Banana Pro model is rolling out across Gemini, Search, Ads and Workspace — and early tests show both mind‑blowing creativity and serious moderation gaps.
What is Google Nano Banana Pro?
Nano Banana Pro is Google DeepMind’s new flagship AI image generation and editing model, officially labeled Gemini 3 Pro Image. It’s the successor to the original Nano Banana (Gemini 2.5 Flash Image) that went viral in late summer 2025 for its toy‑like 3D figurine selfies and creative photo edits. [1]
Announced on November 20 in a Google DeepMind blog post, Nano Banana Pro promises:
- Studio‑quality 2K and 4K images
- Much better text rendering directly inside images
- Richer “world knowledge” via Gemini 3
- Fine‑grained creative controls over lighting, camera, aspect ratio and composition
- Multi‑image blending with consistent characters and branding [2]
Unlike the original Nano Banana, which was positioned as a fun consumer editor, Pro is clearly aimed at designers, marketers, developers and enterprises who need production‑ready visuals, not just memes.
How Nano Banana Pro works under the hood
Nano Banana Pro is built on the Gemini 3 Pro multimodal model, which gives it stronger reasoning and a better grasp of real‑world facts than earlier image generators. [3]
According to Google’s launch and developer posts, the model can: [4]
- Connect to Google Search (when enabled) to ground images in live data — for example, generating an infographic using current weather, sports scores or factual snippets.
- Blend up to ~14 input images into a single composition, while maintaining identity consistency for up to five people — useful for group shots, brand style sheets or storyboard panels.
- Render text in multiple languages inside the image itself, from short slogans to longer paragraphs, with much cleaner spelling, fonts and diacritics than previous models.
- Output in multiple aspect ratios at 2K or 4K resolution, so assets can be used for print, packaging, billboards, or high‑quality video frames.
In practice, that means Nano Banana Pro behaves less like a toy and more like a layout engine plus illustrator plus copy renderer, all fused into one model.
Where you can use Nano Banana Pro today
As of November 21, 2025, Nano Banana Pro is already appearing in multiple Google products and developer tools: [5]
- Gemini app (web, Android, iOS)
- Choose Gemini “Thinking” / Gemini 3 Pro as the model.
- Use the Create images / Images tool to generate or edit visuals.
- Free users get a limited daily quota before the app falls back to the original Nano Banana model.
- Google Workspace
- Integration is rolling out to Slides and Vids, letting users generate slide backgrounds, product shots and storyboards directly in presentations and video projects.
- Google Search & Ads
- In Search’s AI Mode, Pro images are available to higher‑tier subscribers in some regions, especially for data‑driven visuals. [6]
- In Google Ads, Nano Banana Pro is being promoted as a model “built for professional marketing applications,” able to generate campaign‑ready creatives, infographics and localized ad variants. [7]
- Flow (AI video tool)
- Ultra‑tier users gain frame‑level control for storyboards and key art, powered by Nano Banana Pro, according to coverage from Primetimer and Times of India. [8]
- Developers (Google AI Studio, Vertex AI, Antigravity IDE)
Pricing and quotas: How “Pro” is Pro?
Pricing for Nano Banana Pro depends on where you’re using it:
- Consumer Gemini app
- Enterprise & developer usage
- Techloy and other outlets report that in cloud contexts, 2K images are priced around $0.139, while 4K images are roughly $0.24 per generation, compared to about $0.039 for a 1024×1024 image with the older model. [13]
- Google itself frames Nano Banana Pro as the high‑quality, higher‑latency option, while Nano Banana (2.5 Flash) remains the faster, cheaper workhorse for drafts and experiments. [14]
CNET, via regional syndication, points out that a rare Adobe promotion is landing at the same time as Nano Banana Pro’s release, effectively creating one of the cheapest ways to pair Google’s model with professional editing pipelines for heavy image volumes — though that deal is time‑limited and region‑dependent. [15]
Early hands‑on tests: What reviewers are seeing today
Tom’s Guide: Seven “Nano Banana Pro trends” that actually look good
In a feature published today, Tom’s Guide ran seven of the internet’s favorite Nano Banana‑style prompts through Nano Banana Pro, from Funko‑like figurines to camera‑angle gymnastics and age‑progressed portraits. [16]
Key takeaways from their testing:
- Character stylization is more controlled. Turning a child into a chibi‑style collectible figure kept hair, clothing and overall vibe intact, while still looking like a polished 3D render.
- Complex UI scenes are more coherent. A “rhythm game screenshot” prompt produced a convincing arcade‑style interface, with HUD elements and lighting that felt game‑ready rather than chaotic.
- Camera‑angle edits are now practical. Asking Nano Banana Pro to recreate a scene from four angles delivered consistent identity and background, something earlier models struggled with.
- Weather and scene swaps feel natural. Converting a winter scene in Colorado into a sunny beach shot preserved identity and posture while replacing clothing, background and lighting.
- Age‑progression is sharp but recognizable. Aging a subject by 20 years produced a plausible older version without turning them into a different person.
Tom’s Guide also tested the new AI‑detection feature in Gemini by uploading images generated elsewhere (including from a ChatGPT image library). In many cases, Gemini either failed to recognize them as AI or returned an error, suggesting detection is still rolling out and currently best at spotting its own SynthID‑watermarked images. [17]
WIRED: Corporate‑grade text — with lingering quirks
WIRED’s hands‑on today focuses on how Nano Banana Pro changes everyday creative work, especially in business settings. Their tests highlight: [18]
- Markedly improved text rendering. Posters, flyers and web banners with multiple typefaces and full sentences now look much closer to human‑designed layouts, with far fewer nonsense spellings.
- Infographics that actually say something. When asked for a safety infographic on deep‑frying a turkey, Nano Banana Pro produced sensible directions and even referenced a U.S. federal fire‑safety agency.
- Localization that keeps design intact. Example images show product cans where English text is translated into languages like Korean or French while preserving layout and branding.
- Search‑grounded visuals that still need clear prompts. When WIRED asked for an image of what the weather at SFO will be on Thanksgiving, the model produced an airport scene with the forecast tucked into signage — only switching to a more traditional infographic once “infographic” was specified in the prompt.
Even so, WIRED notes ongoing labeling issues (for example, mis‑tagging table items in a Thanksgiving feast diagram), underscoring that the model is powerful but not infallible.
Safety, deepfakes and “conspiracy fuel”
Verge tests: Disturbingly easy to generate sensitive scenes
In a report published this morning, The Verge showed that it was alarmingly easy to coax Nano Banana Pro, via the Gemini app, into generating photorealistic images connected to real‑world tragedies and conspiracy theories. [19]
Their journalists say they were able to create images depicting:
- A second shooter at the JFK assassination site
- A plane striking New York’s Twin Towers
- The White House engulfed in flames
- Cartoon characters placed into scenes of real‑world attacks
Crucially, they report that:
- The model understood historical context even when explicit event names weren’t used.
- Some outputs included dates and text overlays, leveraging the very text‑rendering improvements Google is promoting.
- The free, globally available Nano Banana Pro tier showed little resistance to such prompts during their tests.
The Verge concludes that guardrails are “far from ironclad,” warning that the combination of photorealism, world knowledge and strong text capabilities makes Nano Banana Pro “ripe for abuse” in disinformation campaigns if not tightened quickly. [20]
Google’s response: Watermarks and detection — with big caveats
On the same general launch day, Google and independent outlets highlighted a parallel safety push:
- SynthID Detector in Gemini: Users can now upload an image to the Gemini app and ask whether it was created or edited by Google AI. However, The Register notes that the detector can reliably spot only images that contain Google’s own SynthID watermark, and often fails on images from other models. [21]
- Watermarking & C2PA metadata: Google says that Nano Banana Pro images embed SynthID watermarks and C2PA provenance metadata by default, and that platforms like TikTok are beginning to consume this metadata to label AI content. [22]
- Visible “sparkle” watermark: Most Nano Banana Pro images include a visible Gemini watermark, although Ultra‑tier subscribers and some developer surfaces can opt for clean exports for professional use. [23]
Experts quoted by The Register emphasise that watermark‑based detection remains far from foolproof: research has already shown methods that can strip or disturb watermarks (including SynthID) to the point of evading detectors. [24]
Net result: Nano Banana Pro launches with more provenance tooling than many rivals, but detection alone is not enough, especially if content from the model can be screen‑captured, heavily edited or intentionally obfuscated.
What today’s coverage says Nano Banana Pro means for creators and brands
Putting the November 21 coverage together, a few themes stand out:
- From toy to tool
- Design and marketing workflows will change fast
- Google Ads is already baking Nano Banana Pro into campaign tools, and media reports suggest Slides, Vids and Flow will let non‑designers churn out polished visuals in minutes. [27]
- Wired explicitly warns that corporate AI imagery — “banners, flyers, decks and billboards” — is about to become even more ubiquitous. [28]
- Costs are shifting from “per image” to “per ecosystem”
- On the enterprise side, Pro images are more expensive per render, but pricing is still low enough that thousands of branded images per month are viable for many teams. [29]
- On the consumer side, the cheapest route right now is free app access plus limited‑time software promos (like the Adobe deal flagged by CNET), rather than standalone image‑model subscriptions. [30]
- Safety and regulation debates will intensify
- Stronger text, higher resolution and real‑world knowledge make Nano Banana Pro extremely useful — and also increase the stakes if it’s used for deepfakes, misinformation or harassment. [31]
How to start using Nano Banana Pro (without going down a rabbit hole)
Several guides, including Google’s own “7 tips” post and a step‑by‑step piece from Storyboard18, outline best practices for prompting Nano Banana Pro. [32]
Here’s a distilled, news‑friendly overview:
1. Access Nano Banana Pro in Gemini
- Open gemini.google.com or the Gemini app.
- Sign in with your Google account.
- Select Gemini “Thinking” / Gemini 3 Pro as the model.
- Go to Tools → Create images (wording may vary slightly by region).
- Enter a text prompt or upload a reference image to start editing. [33]
Note: Free users will eventually hit a daily image cap; once that happens, the app reverts to the original Nano Banana model.
2. Write prompts like a creative brief
Google recommends thinking like a director or art lead when prompting: [34]
Include:
- Subject – who/what is in the image e.g., “a stoic robot barista with glowing optics”
- Composition – how it’s framed e.g., “low‑angle wide shot,” “portrait, centered”
- Action – what is happening e.g., “pouring coffee,” “mid‑air kickflip”
- Location – where it takes place e.g., “futuristic café on Mars,” “old town street in Berlin”
- Style – the overall look e.g., “photorealistic,” “90s product photography,” “watercolor illustration”
- Editing instructions (if modifying an existing photo) e.g., “change the suit from black to blue,” “turn daytime into sunset”
3. Use the new Pro controls
Once you’ve got a base image, Nano Banana Pro lets you refine it with: [35]
- Camera and lens controls – angle, depth of field, focal length feel
- Lighting and color grading – “golden hour backlight,” “muted teal and orange”
- Aspect ratio & resolution – square social posts, vertical stories, 16:9 presentation slides, and export at 1K, 2K or 4K
- Image blending – upload multiple references (e.g., product photo, logo, background), and tell the model what to borrow from each
4. Keep ethics and policies in mind
Given what The Verge, The Register and others have demonstrated, it’s worth being extra cautious: [36]
- Avoid prompts that target real people in harmful or misleading contexts.
- Treat any factual diagrams, maps or “news‑style” images with skepticism and double‑check the underlying information.
- Assume that watermarking and detection tools help but do not guarantee provenance — especially once images leave Google’s ecosystem.
Nano Banana Pro vs. Nano Banana (original)
For readers tracking the evolution of Google’s image stack, today’s coverage makes the dividing line clearer: [37]

|---|---|---|
| Underlying model | Gemini 2.5 Flash | Gemini 3 Pro |
| Resolution | Up to 1024×1024 | 2K and 4K options |
| Text rendering | Often distorted or misspelled | Strong, multi‑language, layout‑aware |
| World knowledge & grounding | Limited | Deep reasoning + optional Search |
| Multi‑image blending | Fewer inputs, less consistent | Up to ~14 inputs, 5 identities |
| Ideal use | Fun edits, social media, quick drafts | Branding, infographics, campaign assets |
| Speed & cost | Faster, cheaper | Slower, higher per‑image cost |
FAQ: Nano Banana Pro on November 21, 2025
Is Nano Banana Pro free?
- Yes, with limits. Anyone can try Nano Banana Pro inside the Gemini app on a free tier, but there’s a daily cap on generations; after that, the app rolls back to the original Nano Banana. [38]
- For heavy use, you’ll likely need a paid Gemini / Google AI plan or a developer account with AI Studio / Vertex AI.
Can it really render legible text now?
Multiple outlets — from Dataconomy to WIRED — report that posters, diagrams and UI mockups now contain clearly readable, correctly spelled text, including in languages that previously tripped Google’s models up. [39]
It’s not perfect, but it’s a substantial step up from earlier releases.
How safe is it to rely on watermarking and detection?
Watermarks (SynthID) and provenance metadata (C2PA) are helpful, especially for platforms that actively read them. But:
- They only work reliably when images still contain that metadata or watermark. [40]
- Tools already exist that can weaken or strip watermarks.
- Detection does not replace basic media literacy or human review.
Bottom line for today
On November 21, 2025, Nano Banana Pro looks like:
- One of the most capable AI image tools on the market for text‑heavy, brand‑consistent visuals.
- A new backbone for Google’s own ecosystem of apps, ads and dev tools.
- A flashpoint in the ongoing debate over AI safety, deepfakes and how best to label synthetic media.
If you work in design, marketing or product storytelling, you’ll almost certainly be seeing Nano Banana Pro — whether you ever open the Gemini app yourself or not.
