WAN2.2-14B-I2V-INT8

Uploaded here are some INT8 conversions of various Wan2.2 14B I2V models. All credits go to the original authors

Note: Very few BF16 originals (DaSiWa released v11 of his custom wan2.2 in int8 a bit ago) of custom wan2.2 models like those found on civitai exist, so these models were made in as a minimally lossy way possible as Claude described it.

Steps taken as follows:

Diff custom FP8 with base Wan FP8 -> Take diff and merge with base FP16 Wan -> convert FP16-ish Wan to INT8...

Base Wan FP8 and FP16 from https://huggingface.co/Comfy-Org/Wan_2.2_ComfyUI_Repackaged

Conversion to INT8 from https://github.com/Comfy-Org/comfy-model-tools

Quality looked 'acceptable' to me but YMMV Im guessing since most/all wan 'finetunes' are just a bunch of loras merged with base wan2.2 (there maybe some secret sauce from the author too, i dunno), claude figured this way would lose minimal quality.

If the original authors would like their models removed, i will gladly do so.
