## Files

The checkpoint files mirror the official repository while preserving their repository-relative paths:

| Path | Role |
| --- | --- |
| `Scripts/VAE/ckpt/split/global/MaskedVAE2-HorizonFlip/best.pt` | Global rotation VAE checkpoint |
| `Scripts/VAE/ckpt/split/global/MaskedVAE3-HorizonFlip/best.pt` | Global rotation VAE checkpoint |
| `Scripts/FM/ckpt/split/SimpleSpeechModel/best.zip` | Speech model checkpoint archive |
| `Scripts/FM/EMAGE_VAE/AESKConv_240_100.bin` | Evaluation/representation asset |
See the code repository's environment checker and inference instructions for all runtime dependencies.

Verify the files from the repository root with `sha256sum -c SHA256SUMS`.
