After a few weeks of using Nano Banana Pro, agencies and design or image professionals have delivered their verdict. Google’s image generator and editor offers quality, speed and reduces expenses.
Until now, if tools like Midjourney and DALL-E 3 had the ability to create images with a simple prompt, Nano Banana Pro clearly seems to have taken a step forward. Presented last November by Google, Nano Banana Pro can boast advantages such as text rendering, 4K resolution, multi-element coherence, and editing different visual aspects of an image. It even partially eliminates the need for post-processing via Photoshop. For this, Nano Banana Pro is based on the architecture of Gemini 3 Pro, natively multimodal and capable of reasoning to create or modify visuals. Its cost is not negligible, however, around $0.134 for a 1K/2K image and up to $0.24 for a 4K image. Note that, trained on data prior to January 2025, the content generated includes an invisible SynthID watermark intended to authenticate productions a posteriori.
With these advantages, the tool brings about a daily change among the professionals interviewed. It allows the creation of professional quality visuals and the staging of them. The time and money savings are also interesting. Even if the relevant use of the tool requires solid artistic skills and regular monitoring of performances.
Closet photo shoots
For Jessica Guillot, expert design manager, “Nano Banana Pro generates ultra-realistic visuals of real products in a virtual setting, to populate a brand catalog and web product sheets. The rendering quality and speed of production helped me land projects.” This use has avoided a large part of the traditional costs: recruitment of models, logistics, location rental, photographer, equipment, styling, AD… She explains: “I have completely stopped photo shoots in decorative interiors with models, logistics, or even rentals. I can generate coherent and premium atmospheres, while keeping the product faithful, which really changes the situation.” The gain is considerable for her, even if she does not yet quantify it precisely. “In many cases, this can replace hours of CAD/3D for design and rendering, or hours of photography for the product shoot,” she confides. Note that, beyond these advantages, Nano Banana Pro requires, like most AI tools, rigorous and sometimes time-consuming human management. “Like any tool, you need a minimum of method, with a clear brief, iterations, a product consistency check to obtain a perfectly controlled result,” she says.
Julien Rézette, creative director at Versus AI Agency and head of art at New Business Agency, regularly uses Nano Banana Pro. “We have led several TV, print, digital and social content and creative campaign projects, where Nano Banana Pro played a key role in our production. It allowed us to quickly explore different artistic intentions, test fine variations and arrive at very qualitative visuals, in perfect coherence with the creative directions sought.” This also allowed him, for example, to work for Coperni and Cut By Fred, on projects where AI was used as a real artistic direction tool. “In these cases, Nano Banana Pro allowed us to explore demanding aesthetic universes, to test cutting-edge creative intentions and to produce images very close to reality, while respecting the visual DNA and singularity of each brand.”
4 times faster, 7 times cheaper
Generally speaking, the use of Nano Banana Pro allowed it to go four times faster on average than traditional production. This cost him on average seven times less per project. He nevertheless notes that, “without a strong idea, without a clear creative intention or without a human perspective, AI does not produce anything relevant. The real limit is not the technology, it is the human: the quality of the concept, the artistic direction and the vision. Nano Banana Pro amplifies an idea, but does not replace it.”
Visuals for Google sheets in less than a quarter of an hour
Stéphanie Barge, local SEO specialist, uses Nano Banana Pro in particular for painters and restaurants. “In these cases, the tool allows me to generate images that are ultra realistic, credible and consistent with the client’s activity and their local environment,” she points out. “For a painter, for example, it was a matter of clean and realistic construction site scenes. For restaurants, dining room ambiances by the sea or dishes corresponding to the identity of the place. The objective is not to create “marketing” images, but reassuring and authentic visuals.” Thanks to conversational editing, it can quickly refine images, with natural light, warm atmosphere, Mediterranean context in particular. She integrates this into local pages, Google Business Profiles and editorial content.
“Result: I design more engaging pages, with better credibility and a positive impact on local visibility and the interaction rate,” she explains. Thanks to this, instead of spending around two hours per client searching for images, retouching, adding text, formats, compression, “today, in less than 15 minutes, I have my Google Post and my image”, assures Stéphanie Barge. “I generate a series of 2 to 4 coherent visuals at once to populate each Google Business Profile each week. The time saving is massive, and above all scalable.”
At the same time, it uses Gemini Pro in Deep Research mode to produce scientific or technical content, by cross-referencing sources and structuring complex information. “This makes it possible to create expert, clear and reliable content, understood by both search engines and generative AI.”
She also notes certain precautions in using the tool. “To use it effectively, one must have prior knowledge on the subject matter, in order to verify the generated outputs and correct any possible hallucinations or approximations, whether textual or visual content. One must also remain vigilant on issues of rights and brand safety, in particular for backgrounds or generated visuals. Traceability of prompts and respect for brand identity are essential. Nano Banana Pro is an excellent accelerator for creation and analysis, but it does not replace strategy, business expertise, or knowledge of the field, which remain decisive in producing reliable and differentiating results.” In addition, Nano Banana Pro may also prove counterproductive compared to other tools on the market. Oram Dannreuther, creative director at Infuse IA, advises “putting it in competition with other models, Seedream 4.5, Flux Kontext-Pro in particular. From time to time we obtain better results with them.”
