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 Small BoltzGen structure-conditioned generation checkpoint. Converted small BoltzGen structure-trained checkpoint for structure-conditioned generation. ### Model Provenance - **Upstream Project**: BoltzGen - **Source Checkpoint**: `boltzgen1_structuretrained_small.ckpt` - **Source Release**: [https://huggingface.co/boltzgen/boltzgen-1](https://huggingface.co/boltzgen/boltzgen-1) - **Primary Paper**: [BoltzGen: Toward Universal Binder Design](https://doi.org/10.1101/2025.11.20.689494) - **Upstream License**: MIT for upstream BoltzGen code ### Model Specification | Field | Value | | ----- | ----- | | Repository | `oteam/boltzgen-structure-small` | | Artifact Kind | `pipeline` | | Task | `design_generation` | | Architecture | `boltzgen-structure-small` | | Entrypoint | `ofoldx.pipelines.design.DesignPipeline` | | Source Checkpoint | `boltzgen1_structuretrained_small.ckpt` | > [!NOTE] > Source checkpoint: `boltzgen1_structuretrained_small.ckpt`. ### Links - **Hub repository**: [oteam/boltzgen-structure-small](https://huggingface.co/oteam/boltzgen-structure-small) - **Upstream paper**: [BoltzGen: Toward Universal Binder Design](https://doi.org/10.1101/2025.11.20.689494) - **Upstream repository**: [BoltzGen](https://github.com/HannesStark/boltzgen) - **Source checkpoint release**: [https://huggingface.co/boltzgen/boltzgen-1](https://huggingface.co/boltzgen/boltzgen-1) - **Code**: [`ofoldx/pipelines/design.py`](https://github.com/OTeam-AI4S/OFoldX/tree/main/ofoldx/pipelines/design.py) - **Project repository**: [https://github.com/OTeam-AI4S/OFoldX](https://github.com/OTeam-AI4S/OFoldX) - **Issues**: [https://github.com/OTeam-AI4S/OFoldX/issues](https://github.com/OTeam-AI4S/OFoldX/issues) ## Usage The artifact depends on the [`ofoldx`](https://github.com/OTeam-AI4S/OFoldX) library. Install it with pip: ```bash pip install ofoldx ``` ### Pipeline Usage Load the artifact from `oteam/boltzgen-structure-small` with the OFoldX task pipeline. Use `AutoModel` or `AutoProcessor` only when you need lower-level control: ```python from ofoldx.pipelines import Pipeline pipeline = Pipeline.from_pretrained("oteam/boltzgen-structure-small") ``` 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-structure-small` - **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`; this artifact corresponds to the released small structure-trained checkpoint. ### Training Procedure OFoldX converts the released BoltzGen structure-trained 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. ## Citation Please cite the upstream BoltzGen work for the source checkpoint.
