# LoRA

LoRA is a fast and lightweight training method that inserts and trains a significantly smaller number of parameters instead of all the model parameters. This produces a smaller file (~100 MBs) and makes it easier to quickly train a model to learn a new concept. LoRA weights are typically loaded into the denoiser, text encoder or both. The denoiser usually corresponds to a UNet ([UNet2DConditionModel](/docs/diffusers/pr_12595/en/api/models/unet2d-cond#diffusers.UNet2DConditionModel), for example) or a Transformer ([SD3Transformer2DModel](/docs/diffusers/pr_12595/en/api/models/sd3_transformer2d#diffusers.SD3Transformer2DModel), for example). There are several classes for loading LoRA weights:

- `StableDiffusionLoraLoaderMixin` provides functions for loading and unloading, fusing and unfusing, enabling and disabling, and more functions for managing LoRA weights. This class can be used with any model.
- `StableDiffusionXLLoraLoaderMixin` is a [Stable Diffusion (SDXL)](../../api/pipelines/stable_diffusion/stable_diffusion_xl) version of the `StableDiffusionLoraLoaderMixin` class for loading and saving LoRA weights. It can only be used with the SDXL model.
- `SD3LoraLoaderMixin` provides similar functions for [Stable Diffusion 3](https://huggingface.co/blog/sd3).
- `FluxLoraLoaderMixin` provides similar functions for [Flux](https://huggingface.co/docs/diffusers/main/en/api/pipelines/flux).
- `CogVideoXLoraLoaderMixin` provides similar functions for [CogVideoX](https://huggingface.co/docs/diffusers/main/en/api/pipelines/cogvideox).
- `Mochi1LoraLoaderMixin` provides similar functions for [Mochi](https://huggingface.co/docs/diffusers/main/en/api/pipelines/mochi).
- `AuraFlowLoraLoaderMixin` provides similar functions for [AuraFlow](https://huggingface.co/fal/AuraFlow).
- `LTXVideoLoraLoaderMixin` provides similar functions for [LTX-Video](https://huggingface.co/docs/diffusers/main/en/api/pipelines/ltx_video).
- `SanaLoraLoaderMixin` provides similar functions for [Sana](https://huggingface.co/docs/diffusers/main/en/api/pipelines/sana).
- `HunyuanVideoLoraLoaderMixin` provides similar functions for [HunyuanVideo](https://huggingface.co/docs/diffusers/main/en/api/pipelines/hunyuan_video).
- `Lumina2LoraLoaderMixin` provides similar functions for [Lumina2](https://huggingface.co/docs/diffusers/main/en/api/pipelines/lumina2).
- `WanLoraLoaderMixin` provides similar functions for [Wan](https://huggingface.co/docs/diffusers/main/en/api/pipelines/wan).
- `SkyReelsV2LoraLoaderMixin` provides similar functions for [SkyReels-V2](https://huggingface.co/docs/diffusers/main/en/api/pipelines/skyreels_v2).
- `CogView4LoraLoaderMixin` provides similar functions for [CogView4](https://huggingface.co/docs/diffusers/main/en/api/pipelines/cogview4).
- `AmusedLoraLoaderMixin` is for the [AmusedPipeline](/docs/diffusers/pr_12595/en/api/pipelines/amused#diffusers.AmusedPipeline).
- `HiDreamImageLoraLoaderMixin` provides similar functions for [HiDream Image](https://huggingface.co/docs/diffusers/main/en/api/pipelines/hidream)
- `QwenImageLoraLoaderMixin` provides similar functions for [Qwen Image](https://huggingface.co/docs/diffusers/main/en/api/pipelines/qwen)
- `LoraBaseMixin` provides a base class with several utility methods to fuse, unfuse, unload, LoRAs and more.

Moves the LoRAs listed in `adapter_names` to a target device. Useful for offloading the LoRA to the CPU in case
you want to load multiple adapters and free some GPU memory.

After offloading the LoRA adapters to CPU, as long as the rest of the model is still on GPU, the LoRA adapters
can no longer be used for inference, as that would cause a device mismatch. Remember to set the device back to
GPU before using those LoRA adapters for inference.

  Speed up model loading by only loading the pretrained LoRA weights and not initializing the random

- **hotswap** (`bool`, *optional*) --
  Defaults to `False`. Whether to substitute an existing (LoRA) adapter with the newly loaded adapter
  in-place. This means that, instead of loading an additional adapter, this will take the existing
  adapter weights and replace them with the weights of the new adapter. This can be faster and more
  memory efficient. However, the main advantage of hotswapping is that when the model is compiled with
  torch.compile, loading the new adapter does not require recompilation of the model. When using
  hotswapping, the passed `adapter_name` should be the name of an already loaded adapter.

  If the new adapter and the old adapter have different ranks and/or LoRA alphas (i.e. scaling), you need
  to call an additional method before loading the adapter:

```py
pipeline = ...  # load diffusers pipeline
max_rank = ...  # the highest rank among all LoRAs that you want to load
# call *before* compiling and loading the LoRA adapter
pipeline.enable_lora_hotswap(target_rank=max_rank)
pipeline.load_lora_weights(file_name)

Moves the LoRAs listed in `adapter_names` to a target device. Useful for offloading the LoRA to the CPU in case
you want to load multiple adapters and free some GPU memory.

After offloading the LoRA adapters to CPU, as long as the rest of the model is still on GPU, the LoRA adapters
can no longer be used for inference, as that would cause a device mismatch. Remember to set the device back to
GPU before using those LoRA adapters for inference.

```python
>>> pipe.load_lora_weights(path_1, adapter_name="adapter-1")

>>> image_1 = pipe(**kwargs)
