pytti-vqgan-checkpoints

pytti VQGAN checkpoints (preservation mirror)

First-stage VQGAN checkpoints from CompVis/taming-transformers and community retrainings, as used by pytti and the wider VQGAN+CLIP ecosystem (2020-2021 era).

Why this mirror exists

The original hosts for these files have been decaying for years. eaidata.bmk.sh (the canonical WikiArt host) is already dead, batbot.ai and dl.nmkd.de have been intermittent, the FacesHQ koofr share rejects plain HTTP clients, and the remaining heibox (Heidelberg University) shares are single points of failure. This repo is a verbatim, hash-verified mirror so the pytti toolchain has one stable place to download from.

Every file was verified before upload: size sanity, torch/zip container integrity (torch.load(weights_only=True) where the checkpoint format allows it, zip central directory check otherwise), and sha256 recorded below and in manifest.json.
