This node is primarily used for loading CLIP text encoder models independently. The model files can be detected in the following paths:
  • “ComfyUI/models/text_encoders/”
  • “ComfyUI/models/clip/”
If you save a model after ComfyUI has started, you’ll need to refresh the ComfyUI frontend to get the latest model file path list
Supported model formats:
  • .ckpt
  • .pt
  • .pt2
  • .bin
  • .pth
  • .safetensors
  • .pkl
  • .sft
For more details on the latest model file loading, please refer to folder_paths

Device Options Explained

When to choose “default”:
  • Have sufficient GPU memory
  • Want the best performance
  • Let the system optimize memory usage automatically
When to choose “cpu”:
  • Insufficient GPU memory
  • Need to reserve GPU memory for other models (like UNet)
  • Running in a low VRAM environment
  • Debugging or special purpose needs
Performance Impact Running on CPU will be much slower than GPU, but it can save valuable GPU memory for other more important model components. In memory-constrained environments, putting the CLIP model on CPU is a common optimization strategy.

​
Supported Combinations

As ComfyUI updates, these combinations may expand. For details, please refer to the CLIPLoader class definition in node.py

Additional Notes

CLIP models play a core role as text encoders in ComfyUI, responsible for converting text prompts into numerical representations that diffusion models can understand. You can think of them as translators, responsible for translating your text into a language that large models can understand. Of course, different models have their own “dialects,” so different CLIP encoders are needed between different architectures to complete the text encoding process.
