Media translation with Google Nano Banana Pro
Google’s new powerful image generation model gemini-3-pro-image-preview, also known as “Nano Banana Pro” or referred to as “Nano Banana 2”, can use input images not just as style references, but as an exact original for translation work. Google Deepmind’s product manager Bea Alessio shared several examples for this: one example was a marketing visual featuring two views from different angles on a can of a drink, where the English labels were translated by Nano Banana Pro to Korean. Someone in the live audience remarked that the translation was accurate.
Bea used the Gemini App in her presentation, but the API documentation describes the same “text-and-image-to-image” use case in the “Multi-turn image editing” section:
The prompt shown in the documentation is this (after generating the infographic first:
Update this infographic to be in Spanish. Do not change any other elements of the image.
In my own test, using Google’s Vertex AI platform and a proprietary slide with more text, boxes, icons, … I had success with this prompt:
Make a German version of this slide
Bea’s prompts for the Gemini App may have been more elaborate because it lacks the UI controls for aspect ratio etc. which the Vertex AI Studio has - so this needs to be done in natural language as part of the prompt. Bea at some point hinted at some point that “unusual” aspect ratios could be supported by the Gemini App, but the Vertex AI Studio restricts these to the standard 1:1, 4:3, 16:9, etc. - which are sufficient to translate slides.
Results need to be verified, though: Google Deepmind researcher Yi Tai shared his CV-rendered-as-infographic and his startup “Reka AI” was rendered by Nano Banana Pro as “REKE”.
Availability
Nano Banana Pro is available on Google AI Studio, Vertex AI and several end-user apps like the Gemini App or also NotebookLM. For the API-centric offerings, a paid account seems to be needed. Google AI Studio requires a Billing Account to be linked, with apparently no generations available through the free tier. Low rate limits seem to be an issue (and I experienced cases where I got the “Resource exhausted” error message but simply retrying did the job), and Google’s Logan Kilpatrick offered to e-mail him if higher rates are needed.
Nano Banana Pro is also to be available through third party image generation platforms, including LetzAI.
