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

Parameter	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.

Optional

Parameter	Data Type	Description
extender_args	WANVIDEOPROMPTEXTENDER_ARGS	Configuration for Wan prompt extender helpers.

Outputs

Output Name	Data Type	Description
text_embeds	WANVIDEOTEXTEMBEDS	Positive/negative embedding bundle for Wan samplers.
negative_text_embeds	WANVIDEOTEXTEMBEDS	Negative-only embeddings (for workflows that split branches).
positive_prompt	STRING	The positive prompt as finalised by the extender (handy for preview nodes).
