WanVideo Tea Cache (native)

KJNodes/teacacheDeprecatedExperimental

WanVideoTeaCacheKJ

Patch WanVideo model to use TeaCache. Speeds up inference by caching the output and applying it instead of doing the step. Best results are achieved by choosing the appropriate coefficients for the model. Early steps should never be skipped, with too aggressive values this can happen and the motion suffers. Starting later can help with that too. When NOT using coefficients, the threshold value should be about 10 times smaller than the value used with coefficients. Official recommended values https://github.com/ali-vilab/TeaCache/tree/main/TeaCache4Wan2.1

Deprecated: This node is deprecated and may be removed in future versions. Consider using an alternative node if available.

Experimental: This node is experimental and its behavior may change without notice.

JSON Example

{
  "class_type": "WanVideoTeaCacheKJ",
  "inputs": {
    "model": [
      "node_id",
      0
    ],
    "rel_l1_thresh": 0.275,

}

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

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 WanVideoTeaCacheKJ 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]
