Google’s new image generator, officially named Gemini 3 Pro Image, fundamentally changes how AI creates visuals. Instead of immediately generating a result from a prompt, the model first enters a “Thinking Mode” to reason, critique, and correct its own plan.
Stephen Smith writes in Intelligence by Intent that this new approach marks a significant shift. He describes the model, also know under its nickname “Nano Banana Pro”, as a “multimodal reasoning engine wrapped in an image generator”. This reasoning step allows the AI to produce 4K resolution images with legible text and consistent characters across a series of pictures.
According to Smith, the new system eliminates the need for specialized and expensive programming to maintain brand consistency in marketing campaigns. The tool can use reference images for products and logos and is integrated directly into Google Workspace. Smith notes that it can create detailed storyboards, generate localized ad creatives with multilingual text, and understand complex negative instructions, such as removing an object but keeping its shadow.
The new capabilities come with trade-offs. Smith points out that the process is slower and more expensive than previous models. It also employs very strict safety filters to prevent the creation of harmful content or copyright infringement.
