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...
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.
