| # SD3Transformer2D | |
| This class is useful when *only* loading weights into a [`SD3Transformer2DModel`]. If you need to load weights into the text encoder or a text encoder and SD3Transformer2DModel, check [`SD3LoraLoaderMixin`](lora#diffusers.loaders.SD3LoraLoaderMixin) class instead. | |
| The [`SD3Transformer2DLoadersMixin`] class currently only loads IP-Adapter weights, but will be used in the future to save weights and load LoRAs. | |
| > [!TIP] | |
| > To learn more about how to load LoRA weights, see the [LoRA](../../tutorials/using_peft_for_inference) loading guide. | |
