Model artifacts

The release includes every local checkpoint needed by the submitted PDC generation code. Run python scripts/verify_release.py to verify byte counts, SHA-256 hashes, and private-path hygiene. The machine-readable manifest is in docs/artifacts.json.

ESM-2 (facebook/esm2_t33_650M_UR50D) and PeptideCLM (aaronfeller/PeptideCLM-23M-all) are downloaded from Hugging Face on first use and therefore are not duplicated here.

The optional AA-input binding predictor was not used for the reported PDC runs, which used --affinity_type smiles, and is intentionally excluded (it would add about 2.7 GB). The public wrapper passes the reported SMILES-input setting explicitly.

When publishing with hf upload, the Hugging Face Hub client handles large-file storage. If this release is mirrored to a Git LFS remote:

git lfs install
git lfs track "*.pt" "*.ckpt"
git add .gitattributes checkpoints smiles/scoring/checkpoints
