| # rfdiffusion-complex-base |
|
|
| OFoldX `pipeline` artifact for biomolecular design generation, using the `rfdiffusion` 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 |
|
|
| RFdiffusion backbone-generation model for protein design and motif scaffolding. |
|
|
| Converted RFdiffusion checkpoint for backbone generation, motif scaffolding, and binder design. |
|
|

|
|
| ## 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/rfdiffusion-complex-base` 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/rfdiffusion-complex-base") |
| ``` |
|
|
| 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**: `rfdiffusion` |
| - **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 |
|
|
| RFdiffusion fine-tunes a RoseTTAFold-style structure network as a denoising diffusion model over PDB protein structures. OFoldX does not redistribute the training set. |
|
|
| ### Training Procedure |
|
|
| Upstream RFdiffusion noises residue frames with Gaussian C-alpha translation noise and rotational Brownian motion, trains denoising to true frames with self-conditioning, and uses checkpoint-specific inference configs. OFoldX converts released RFdiffusion checkpoints into `model.safetensors`; it does not run RFdiffusion 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. |
