UNETLoader

Example

JSON Example

{
  "class_type": "UNETLoader",
  "inputs": {
    "unet_name": "https://huggingface.co/black-forest-labs/FLUX.1-schnell/resolve/main/flux1-schnell.safetensors",
    "weight_dtype": "default"
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
unet_name	ENUM 0 options URL: UNet	required	-	-
weight_dtype	ENUM 4 options default fp8_e4m3fn fp8_e4m3fn_fast fp8_e5m2	required	-	-

Outputs

Index	Name	Type	Is List	Connection Reference
0	MODEL	MODEL	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this UNETLoader node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• MODEL (MODEL): ["5", 0]
