For example, to speedup training with mixed precision using the bf16 format, add the `--mixed_precision` parameter to the training command:  
```bash
accelerate launch train_text_to_image_sdxl.py \
--mixed_precision="bf16"
```  
Most of the parameters are identical to the parameters in the [Text-to-image](text2image#script-parameters) training guide, so you'll focus on the parameters that are relevant to training SDXL in this guide.
