boltzgen-adherence

OFoldX pipeline artifact for biomolecular design generation, using the boltzgen-adherence 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

BoltzGen design generator variant optimized for adherence to conditioning signals.

Converted BoltzGen adherence generator checkpoint for controllable binder and protein design.

Usage

The artifact depends on the ofoldx library. Install it with pip:

pip install ofoldx

Pipeline Usage

Load the artifact from oteam/boltzgen-adherence with the OFoldX task pipeline. Use AutoModel or AutoProcessor only when you need lower-level control:

from ofoldx.pipelines import Pipeline

pipeline = Pipeline.from_pretrained("oteam/boltzgen-adherence")

When a matching processor is available, load it with AutoProcessor.from_pretrained(...) and pass the processed batch to the model.

Interface

• Task: design_generation
• Artifact kind: pipeline
• Architecture: boltzgen-adherence
• 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

BoltzGen builds on the Boltz-2 data pipeline. The public training release includes targets.zip and msa.zip in the boltzgen/boltzgen1_train dataset and molecule dictionaries in boltzgen/inference-data; the full large-model recipe may also use additional distillation data.

Training Procedure

Upstream BoltzGen trains a diffusion objective over randomly cropped biomolecular structures with randomly selected design and conditioning regions. OFoldX converts the released adherence checkpoint; it does not run BoltzGen 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.
