This extension provides TensorRT optimization for Stable Diffusion Web UI (Automatic1111), enabling faster image generation on NVIDIA RTX GPUs. Users generate optimized inference engines for specific resolutions and batch sizes before use. The extension supports Stable Diffusion 1.5, 2.1, SDXL, SDXL Turbo, and LCM models, with recommended GPU requirements of 12 GB VRAM for SDXL variants. It also includes LoRA/LyCORIS checkpoint conversion to TensorRT format for use with the extension.
