 ### Faster Text-to-Image using SDXL + LCM (Latent Consistency Model) LoRA weights
 [LCM-LoRA](https://arxiv.org/abs/2311.05556) produces good quality images in 4 to 8 denoising steps instead of 30+ needed base model. Note that we use LCM scheduler and disable classifier-free-guidance by setting `--guidance-scale` to 0.
 LoRA weights are fused into the ONNX and finalized TensorRT plan files in this example.
