Corporate AI visuals are everywhere in 2025, from website banner ads to billboards and the local bar’s happy hour flyer, all carrying that same hazy, amber glow common to many AI graphics. Google hopes its newest image model will make those assets look sharper and read cleaner.
On Thursday, Google introduced Nano Banana Pro, an upgraded image-generation model aimed squarely at business users. The company is rolling the model into Google Slides for presentations and connecting it with Google Ads so advertisers worldwide can generate campaign art from prompts.
The “Pro” edition grows out of the Nano Banana model that launched earlier this year. Nano Banana turned into an online hit after people shared custom action figures and other meme-worthy creations on social networks.
Nano Banana Pro adds several capabilities, including the ability to output images at 4K resolution. Anyone can try it inside Google’s Gemini app for free; paid Google One members receive extra generations.
A major improvement companies will appreciate is text rendering. In early tests that mixed words and visuals, Nano Banana Pro reduced the warped lettering and odd misspellings that have plagued many image models, even Google’s earlier tools. Nicole Brichtova, a product lead for image and video at Google DeepMind, said a single wrong character jumps out and that such mistakes are often the first thing viewers notice. She credited part of the change to the shift to a more powerful underlying model, Gemini 3 Pro.
The model can combine multiple images into a single composite with surprising detail. My mock flyers and web banners still sometimes showed the faint yellow tint common in AI-generated art, yet Nano Banana Pro managed to produce fairly detailed marketing pieces, generating full sentences in varied typefaces from a single prompt. Users can request edits after the initial result, such as removing an element or shifting the overall style.
Brichtova said the better text handling has made infographics significantly stronger in Nano Banana Pro. In tests I ran, that held up: an infographic about how to deep-fry a turkey came with sensible steps and included warnings cited from the US Fire Administration, along with other appropriate safety notes.
Labeling within images remained a weak spot on day one. When I asked the model to create a picture of a Thanksgiving spread and then tag every item, the AI misapplied labels. An arrow aimed at a spoon read “Autumn leaves.” An empty plate near a pecan pie was labeled as the pie itself. A bare patch on the table was marked “dinner rolls,” though no bread appeared in the scene.
Please don’t invite me to your fall feast if there’s no bread. Please.
The update improves language rendering, too. Brichtova said she had not seen the models render Czech with correct diacritics until now. Brands can ask Google to swap text on visuals into other languages for localization. In its announcement blog, Google showed an energy drink can whose English text was changed to Korean while the rest of the design remained intact.
Nano Banana Pro can also adjust lighting and color in photos, giving users control over tone and mood. The model’s connection to Google Search lets it pull current facts from the web and fold them into generated graphics, though prompt phrasing matters.
I tested that by asking for an image showing the weather at SFO on Thanksgiving Day. The first results looked like a photorealistic airport gate area with a big window and two people in puffer jackets. A tiny blue sign in the corner displayed the date and a predicted temperature. Rewording the prompt produced similar outputs; only when I specified that I wanted an “infographic” did Nano Banana Pro return a cartoon-style forecast with data sourced from Google Weather.
The improvements aren’t flawless, but they answer a clear demand. Businesses want higher-resolution images and cheaper ways to create promotional material. That will lead to more AI-produced assets in marketing and internal communications. On a personal note, I’m not confident I’ll sit through many AI-powered slide decks without drifting off, even when the words render correctly.
Nano Banana Pro’s free access in Gemini and its Ads and Slides connections make it simple for companies to start experimenting. Paid Google One users get more generation capacity for regular use. The mix of better typography, language support and web awareness gives teams a faster path from idea to final graphic, and marketing departments are likely to put the tool to immediate use.
