Stable Diffusion WebUI Forge, developed with Stable Diffusion WebUI and Gradio, aims to optimize resource management and accelerate inference. Compared to the original WebUI, Forge can boost SDXL inference speed by 30-75% at 1024px resolution, increase the maximum resolution by 2-3 times, and enlarge the maximum batch size by 4-6 times. Forge retains all the functionalities of the original WebUI while adding samplers like DDPM, DPM++, and LCM, enabling algorithms such as Free U, SVD, and Zero123. Its UNet Patcher allows developers to implement algorithms with minimal code. Forge also optimizes control network usage, achieving true zero-memory occupancy calls.
