    Nvidia drops PID 1.5 to upscale AI images in seconds

    Nvidia just updated its open-source PID decoder to version 1.5, bringing sharper detail and cleaner color fidelity without grid artifacts. It turns 512×512 latents straight into 2K or 4K renders on consumer GPUs in mere seconds. Why it matters: it bypasses slow, two-step upscaling workflows and works out of the box with models like FLUX and Qwen-Image.

    Nvidia's PiD fixes blurry AI image decoding in under a second

    Nvidia just introduced PiD, a pixel diffusion decoder designed to replace traditional VAEs and eliminate blurry high-resolution AI images. By turning decoding and upsampling into a four-step diffusion process, it renders 2K images from latents in under one second on an RTX 5090. Why it matters: It wipes out the slowest, most blur-prone bottleneck in modern image generation.
