NVIDIA’s GauGAN2 is a real-time generative tool that turns sketches, images, and detailed text prompts into photorealistic results, performing text-guided inpainting and global light/reflection updates automatically. Compared to the 2019 GauGAN it offers roughly 4× resolution, broader material support, interactive per-keystroke updates, and is distributed as NVIDIA Canvas (desktop GPU) plus a web app with layered Photoshop export.
