# Cuttlefish-Encoder

Graph encoder component of **Cuttlefish**, a unified all-atom LLM that grounds language reasoning in geometric cues while scaling modality tokens with structural complexity.

This model was presented in the paper [Scaling-Aware Adapter for Structure-Grounded LLM Reasoning](https://arxiv.org/abs/2602.02780).

- **Code:** [GitHub - zihao-jing/Cuttlefish](https://github.com/zihao-jing/Cuttlefish)
- **Pretrained with:** Masked reconstruction on all-atom structures.

## Usage

You can download the encoder using the `huggingface_hub` library:

```python
from huggingface_hub import snapshot_download
encoder_dir = snapshot_download("zihaojing/Cuttlefish-Encoder")

# Load via the Cuttlefish codebase
# See https://github.com/zihao-jing/Cuttlefish for full usage
```

## Pretraining data

Pretrained on **[Cuttlefish-Encoder-Data](https://huggingface.co/datasets/zihaojing/Cuttlefish-Encoder-Data)**, covering:
- Molecules (SMILES → 3D graph)
- Proteins (PDB/CIF → all-atom graph)
- DNA and RNA sequences

## Model details

- **Architecture**: All-atom graph encoder with Scaling-Aware Patching.
- **Encoder hidden dim**: 256
- **Modalities**: molecule, protein, dna, rna
