# How to upscale an image with AI

**How do I upscale an image with AI?**

Run the finished image through an AI upscaler. In OTOY Studio that is Topaz Image Upscale, usually the last node in an image workflow. Nano Banana Pro can also generate directly at up to 4K, which saves the extra step for new images.
