# 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.

### Model Provenance

- **Upstream Project**: RFdiffusion
- **Source Release**: [https://github.com/RosettaCommons/RFdiffusion/blob/main/scripts/download_models.sh](https://github.com/RosettaCommons/RFdiffusion/blob/main/scripts/download_models.sh)
- **Primary Paper**: [De novo design of protein structure and function with RFdiffusion](https://doi.org/10.1038/s41586-023-06415-8)
- **Upstream License**: BSD for upstream RFdiffusion code and referenced model weights

## 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.
