SDXL LoRA Training: Best Settings and Practical Workflow

Training LoRAs for SDXL requires different settings than SD 1.5. This guide provides optimized configurations: recommended rank 32-64 for SDXL (higher than SD 1.5), alpha typically equals rank for SDXL, learning rate 1e-4 with Prodigy optimizer (auto-adjusting), resolution 1024x1024 with bucket aspect ratios, 1500-3000 training steps depending on dataset size, mixed precision bf16 for modern GPUs. Covers dataset preparation best practices, captioning strategies for SDXL's dual text encoder, SDXL-specific augmentation settings, training monitoring with TensorBoard, and common failure modes with solutions.
