Open-H3-Regenerate-2K is an open-source repo in our Generation category. NVIDIA's open refiner for MiniMax H3: draft at 768p, upsample the latent, and a LoRA regenerates it at 2560×1440 (up to 4K) in three Euler steps, with a sharpening LoRA and a fast H3 VAE. Authors claim a 5 s 2K clip in 22.45 s on one B200, about 5× the official 2K API. Re-draws detail like img2img, so faces and text can shift. Kijai's rank-16 to rank-384 LoRAs cut the 12 GB file to 0.15 to 6 GB. MiniMax H3 Community License plus mixed component licences.
