WanVideoTextEncodeCachedMultiGPU
WanVideoTextEncodeCachedMultiGPU is a convenience wrapper that loads a Wan T5 encoder on demand, produces prompt embeddings, and fully unloads the encoder when finished. It favours disk caching so repeated prompts can reuse saved embeddings without re-running the model.
Inputs
Required

Data Type |
Description |
model_name |
STRING |
T5 encoder to load from ComfyUI/models/text_encoders. |
precision |
STRING |
Precision for the temporary encoder (fp32 or bf16). |
positive_prompt |
STRING |
Prompt text for the conditioned branch. |
negative_prompt |
STRING |
Prompt text for the unconditioned branch. |
quantization |
STRING |
FP8 switch (disabled or fp8_e4m3fn). |
use_disk_cache |
BOOLEAN |
Enables Wan disk caching for embeddings. |
load_device |
STRING |
MultiGPU device that will host the one-shot encoder. |
