Hands On With Google’s Nano Banana Pro Image Generator

Corporate AI slop feels inescapable in 2025. From website banner ads to outdoor billboards, images generated by businesses using AI tools surround me. Hell, even the bar down the street posts happy hour flyers with that distinctly hazy, amber glow of some AI graphics.

On Thursday, Google launched Nano Banana Pro, the company’s latest image generating model. Many of the updates in this release are targeted at corporate adoption, from putting Nano Banana Pro in Google Slides for business presentations to integrating the new model with Google Ads for advertisers globally.

This “Pro” release is an iteration on its Nano Banana model that dropped earlier this year. Nano Banana became a viral sensation after users started posting personalized action figures and other meme-able creations on social media.

Nano Banana Pro builds out the AI tool with a bevy of new abilities, like generating images in 4K resolution. It’s free to try out inside Google’s Gemini app, with paid Google One subscribers getting access to additional generations.

One specific improvement is going to be catnip for corporations in this release: text rendering. From my initial tests generating outputs with text, Nano Banana Pro improves on the wonky lettering and strange misspellings common in many image models, including Google’s past releases.

Google wants the images generated by this new model—text and all—to be more polished and production-ready for business use cases. “Even if you have one letter off it’s very obvious,” says Nicole Brichtova, a product lead for image and video at Google DeepMind. “It’s kind of like having hands with six fingers; it’s the first thing you see.” She says part of the reason Nano Banana Pro is able to generate text more cleanly is the switch to a more powerful underlying model, Gemini 3 Pro.

The mock flyers and web banner ads I generated still sometimes had that yellowish tint prevalent in AI-generated graphics. Even so, Nano Banana Pro was able to put together fairly detailed marketing materials, with full sentences in multiple typefaces, from a single prompt. You can ask for tweaks to the image in a follow-up prompt, like removing a certain detail or adjusting the overall style.

Brichtova says this improved text rendering has made the creation of infographics markedly better in Nano Banana Pro. In some of my initial tests, that proved to be true. The infographic the tool generated on how to deep fry a turkey included reasonable directions and cited warnings from the US Fire Administration, a federal agency, as well as other proper safety precautions.

“The model now uses Gemini’s world knowledge and reasoning to be able to make not just beautiful visuals but also informative visuals,” says Brichtova. “You can make an infographic about your favorite animal, or you could make a visual that you can put into a work presentation.” White collar workers can expect to see AI visuals in the workplace, from presentation slides to promotional materials, even more often than they already do.

Where Nano Banana Pro still struggled in my day-one tests was at image labeling. When asked to generate an image of a Thanksgiving feast laid out on a table and then label everything in the image, the AI output included an arrow pointing to a spoon that was labeled as “Autumn leaves.” An empty plate near the pecan pie was labeled as if it was the pecan pie. And a bare spot on the table was marked as “dinner rolls,” despite no bread appearing at the table at all.

Please don’t invite me to your fall feast if there’s no bread. Please.

Another aspect of Nano Banana Pro’s update is generating text in additional languages. “It’s the first time I’ve seen our models be able to render Czech, with the diacritics and everything,” says Brichtova. Companies can request brand visuals to be switched to other languages for localization purposes. Google’s announcement blog shows the tools changing the words on an energy drink can from English to Korean, while preserving the other design elements.

Since the AI tool is connected to Google Search, Nano Banana Pro can pull details from the web and incorporate them into the graphics it spits out. Though to get the best results, you have to be specific.

With many American’s holiday travels in mind, I entered the prompt: “Create an image with what the weather will be like at SFO on Thanksgiving Day.” The output confused me at first. It was a photorealistic image of the inside of an airport, near a boarding gate with a nice view out of a large wall of windows. Two people in matching puffer jackets were milling about. Looking closer, I noticed a small blue sign in the corner of the image displaying Thanksgiving’s date and the predicted temperature.

Nano Banana Pro is much better at making infographics from scratch.

After a few tries at rewording the prompt and getting similar results, it was only when I specified that I wanted an “infographic” rather than an “image” that Nano Banana Pro spit out a cartoonish forecast with data sourced from Google Weather.

Despite the rough edges, Nano Banana Pro is likely to have staying power. Companies want higher resolution outputs and ways to create marketing assets for even cheaper. The era of corporate AI slop, generated by businesses for internal and external purposes, is blossoming. Though, personally, I’m not sure how many AI-powered presentations I can sit through without falling asleep, even if the text is correctly generated.
