ligandmpnn-noise010
OFoldX pipeline artifact for biomolecular design generation, using the ligandmpnn architecture.
Disclaimer
This model card was generated by the OFoldX team for an OFoldX pipeline artifact.
The upstream model authors did not write this card unless explicitly stated otherwise.
OFoldX is pre-alpha research software. Check the source checkpoint, upstream release, and local validation
before using the artifact for scientific or operational decisions.
Model Details
LigandMPNN sequence-design model with ligand/atom context features.
Converted LigandMPNN sequence-design checkpoint with ligand and non-protein atom context.
Model Provenance
- Upstream Project: LigandMPNN
- Primary Paper: Atomic context-conditioned protein sequence design using LigandMPNN
- Upstream License: MIT for upstream LigandMPNN code and model parameters

Usage
The artifact depends on the
ofoldx library. Install it with pip:
Pipeline Usage
Load the artifact from oteam/ligandmpnn-noise010 with the OFoldX task pipeline. Use AutoModel or AutoProcessor only when you need lower-level control:
1from ofoldx.pipelines import Pipeline
2
3pipeline = Pipeline.from_pretrained("oteam/ligandmpnn-noise010")
When a matching processor is available, load it with AutoProcessor.from_pretrained(...) and pass the
processed batch to the model.
Interface
- Task:

- Artifact kind:

- Architecture:

- Runtime files:
manifest.json, config.json, and model.safetensors when present
Training Details
OFoldX did not train these weights. This repository contains a converted checkpoint and OFoldX runtime
metadata for loading it.
Training Data
LigandMPNN was trained on PDB assemblies as of 2022-12-16 from X-ray crystallography or cryo-EM structures better than 3.5 A and shorter than 6,000 residues, with 30% sequence-identity clustering and non-protein atomic context such as ligands, nucleic acids, and metals. OFoldX does not redistribute the training set.
Training Procedure
Upstream LigandMPNN uses categorical cross-entropy sequence-design training with Adam, mixed precision/checkpointing, and released noisy-backbone checkpoint variants. OFoldX converts released LigandMPNN checkpoints into model.safetensors; it does not run LigandMPNN training.
Evaluation
OFoldX conversion reports and contract tests validate artifact structure and checkpoint loading. Task-level
scientific evaluation should be checked against the corresponding upstream model release or paper.
Limitations
- This artifact is distributed for research use.
- Inputs must match the model-specific processor and expected biomolecular representation.
- OFoldX is pre-alpha, so APIs and artifact metadata may still change before a stable release.
