HiDream-Studio v.01 open-sourced: 20s per image on 4090 at 2K
New open-source image gen runs 20s per image at 2048x2048 on a single RTX 4090.
HiDream-Studio v.01, released on GitHub by user gjnave, brings fast, open-source image generation to the community. Built as a PySide application (a Python GUI framework), it achieves impressive performance: approximately 20 seconds per image at a resolution of 2048x2048 on an RTX 4090. The model is specifically optimized for square resolutions like 2048x2048 and 1024x1024; using odd or non-square resolutions can actually degrade speed. This makes it ideal for high-res generation tasks without needing complex ComfyUI workflows.
Installation is remarkably straightforward: clone the repository and double-click the install.bat file. The developer notes that while ComfyUI typically runs faster for similar models, this PySide app is surprisingly efficient. For professionals and enthusiasts with capable hardware, HiDream-Studio v.01 lowers the barrier to generating high-quality 2K images quickly. Its open-source nature invites further optimization and customization, potentially accelerating adoption for creative and research workflows.
