### PixArt LCM
The LCM model also works if you're on the latest version. To use it:
1. Download the [PixArt LCM model](https://huggingface.co/PixArt-alpha/PixArt-LCM-XL-2-1024-MS/blob/main/transformer/diffusion_pytorch_model.safetensors) and place it in your checkpoints folder.
2. Add a `ModelSamplingDiscrete` node and set "sampling" to "lcm"
3. Adjust the KSampler settings - Set the sampler to "lcm". Your CFG should be fairly low (1.1-1.5), your steps should be around 5.
Everything else can be the same the same as in the example above.
