Can Nano Banana Pro Upscale Images? Here’s the Answer
In this tutorial, the instructor (Kush Sharma) explores whether Nano Banana Pro (Google’s Gemini 3 Pro image model) can be used as an image upscaler. While technically an image generator and not an upscaling tool, the video demonstrates a “hack” using a highly detailed prompt to force the model to behave like one. However, after a side-by-side comparison with a dedicated AI upscaler (Topaz Generative Upscale), the instructor concludes that while Nano Banana Pro can improve an image’s sharpness, it cannot match the specialized pattern recognition and micro-texture reconstruction of a dedicated upscaling tool. Here’s the video:
