Current Supported Models:

LongCat 6B Image
LongCat 6B Image Edit
GLM Image (Text-to-Image)
GLM Image (Image-to-Image)

Installation

Clone this repository into your ComfyUI custom_nodes directory:

cd ComfyUI/custom_nodes

Restart ComfyUI

Available Nodes

Pipeline Loading Node

Diffusers Pipeline Loader (`DiffusersPipeline`)

Initializes different LongCat diffusion pipelines with dynamic components.

Inputs:
- pipeline_class_name: Select pipeline type ("LongCatImagePipeline" or "LongCatImageEditPipeline")
- model_path: Path to the model directory
- pipeline: Existing pipeline (optional, for component swapping)
- torch_dtype: Data type (float16, float32, bfloat16) - Default: bfloat16
- components: Comma-separated list of components to load (optional)
- presets: Predefined component sets to load - Default: "text_encoder, tokenizer, text_processor"
Outputs:
- pipeline: The loaded pipeline object
Category: Diffusers/LongCat

Text Encoding Node

Diffusers Text Encode (`DiffusersTextEncode`)

Encodes text prompts using the pipeline's text encoder. Supports both text-only and text+image encoding depending on the pipeline type.

Inputs:
- pipeline: The loaded pipeline object
- prompt: Text prompt to encode (multiline, default: "Masterpiece, best quality, 8k uhd, photo realistic,")
- image: Optional image input for pipelines that support text+image encoding
- batch_size: Number of images to generate (default: 1, min: 1, max: 64)
Outputs:
- diffusers_cond: Conditioning information for sampling
Category: Diffusers/Encode

Sampling Node

Diffusers Sampling (`DiffusersSampling`)

Performs the generation loop using a pipeline and conditioning to generate images using the diffusion process.

Inputs:
- pipeline: Loaded diffusion pipeline
- diffusers_cond: Conditioning from DiffusersTextEncode node
- steps: Number of inference steps (default: 26, min: 1, max: 100)
- cfg: Guidance scale (default: 1.5, min: 0.0, max: 20.0)
- negative_diffusers_cond: Negative conditioning (optional)
- num_images_per_prompt: Number of images to generate per prompt (default: 1, min: 1, max: 8)
- seed: Random seed for generation (default: 42, range: 0 to 0xffffffffffffffff)
- image: Input image for image editing (optional)
- width: Output image width (for regular generation, or override for editing) (default: 1024, min: 256, max: 4096, step: 64)
- height: Output image height (for regular generation, or override for editing) (default: 1024, min: 256, max: 4096, step: 64)
Outputs:
- image: Generated image(s)
Category: Diffusers/Sampling

LoRA Utility Nodes

Diffusers Load LoRA Only (`DiffusersLoadLoraOnly`)

Load a LoRA file without applying it to any models. Use with MergeLoraToModel or other nodes to apply the LoRA later.

Inputs:
- lora_path: Path to the LoRA file
Outputs:
- lora: The loaded LoRA state dictionary
Category: Diffusers/Lora

Diffusers LoRA Layers Operation (`DiffusersLoraLayersOperation`)

Modify specific layers in a LoRA by zeroing them out (when scale=0) or scaling them (otherwise) based on pattern matching.

Inputs:
- lora: The LoRA state dictionary to modify
- layer_pattern: Regex pattern to match layer names (default: .*transformer_blocks\.(\d+)\.)
- layer_indices: Comma-separated list of layer indices to operate on, with support for ranges (e.g., '59', '10,11,12', or '50-53') (default: '59')
- scale_factor: Scale factor to apply. Use 0 to zero out layers (default: 1.0, range: -10.0 to 10.0)
Outputs:
- modified_lora: The modified LoRA state dictionary
Category: Diffusers/Lora

Diffusers Save LoRA (`DiffusersSaveLora`)

Save a modified LoRA state dictionary to a file.

Inputs:
- lora: The modified LoRA state dictionary to save
- filename: Filename to save the LoRA as (e.g. my_lora.safetensors) (default: "my_lora.safetensors")
- output_dir: Directory to save the LoRA to (optional, defaults to ComfyUI output directory)
Outputs:
- None (saves file to specified location)
Category: Diffusers/Lora

Diffusers LoRA Stat Viewer (`DiffusersLoraStatViewer`)

View information about LoRA layers to help define layer patterns for LoraLayersOperation.

Inputs:
- lora: The loaded LoRA to analyze
Outputs:
- lora_info: Information about the LoRA layers
Category: Diffusers/Lora

Diffusers Merge LoRA to Pipeline (`DiffusersMergeLoraToPipeline`)

Apply a pre-loaded LoRA to transformer. This allows separation of loading and applying LoRAs.

Inputs:
- pipeline: The pipeline to apply the LoRA to
- lora: The loaded LoRA to apply
- strength: How strongly to modify the diffusion model. This value can be negative (default: 1.0, range: -10.0 to 10.0)
- adapter_name: The name of the adapter to use (default: "default")
Outputs:
- pipeline: The modified pipeline
Category: Diffusers/Lora

Usage Examples

The nodes are designed to work together in a pipeline:

Use DiffusersPipeline to load your model (select appropriate pipeline type)
Encode your prompts using DiffusersTextEncode (with optional image for edit pipelines)
Apply LoRAs if desired using the LoRA utility nodes:
- Load with DiffusersLoadLoraOnly
- Modify with DiffusersLoraLayersOperation (optional)
- Apply to pipeline with DiffusersMergeLoraToPipeline
Generate images using DiffusersSampling with your conditioning and parameters

For image editing workflows, use LongCatImageEditPipeline with an input image to the sampling node.
