V1

Workflow for Wan 2.1 text to video that can generate a small resolution video first, then upscales it when you find one you like. The workflow has teacache and sage attention to reduce generation time, but sage does requires triton to run.

If you don't want to use sage attention or don't have triton installed, you can just bypass the node.

V2

Changed the workflow slightly to make it faster to run while keeping quality.
