ComfyUI-AIT

A ComfyUI implementation of Meta's AITemplate repo for faster inference using cpp/cuda. The old AIT repo is still available for reference. You can find it here. The node in the UI is located under loaders->AIT. This new repo is behiond but is a much more stable foundation to keep AIT online. Please be patient as the repo will eventually include the same features as before.

Modules

You can find already compiled modules here otherwise you can compile your own modules (requires sm80 or higher NVIDIA GPU).

a bundle for Windows compilation is included with this repo. See Windows installation instructions.

Place your downloaded or compiles Modules in the ComfyUI/models/ait directory.

While in ComfyUI, simply hook up the AIT_Unet_Loader to your workflow and select a module that is equal to or larger than the resolution you are generating at.
