# ThinkingViT DeiT 3H -> 6H 800 Epochs ImageNet-1K

This repository contains the ImageNet-1K EMA weights for **ThinkingViT DeiT 3H -> 6H 800 Epochs ImageNet-1K** from
[ThinkingViT: Matryoshka Thinking Vision Transformer for Elastic Inference](https://arxiv.org/abs/2507.10800).

- Paper: https://arxiv.org/abs/2507.10800
- Hugging Face paper: https://huggingface.co/papers/2507.10800
- Code: https://github.com/ds-kiel/ThinkingViT
- Project page: https://ds-kiel.github.io/ThinkingViT-project-page/
- Exported checkpoint key: `state_dict_ema`
- Weight format: `model.safetensors`

## Usage

```python
import torch
from timm.models import create_model

# Run from the ThinkingViT repository root, or put this repository on PYTHONPATH.
model = create_model("hf-hub:NCPS/thinkingvit_deit-3h-6h-800epochs-imagenet1k", pretrained=True)
model.eval()

x = torch.randn(1, 3, 224, 224)
with torch.no_grad():
    logits, stage = model(x, threshold=1.0)
print(logits.shape, stage)
```


This is a custom timm-based architecture. Use the code from the ThinkingViT repository when loading this model.

## Threshold Behavior

The entropy threshold controls early exit. Lower thresholds send more samples to the 6-head stage; higher thresholds exit earlier at the 3-head stage.
