# Reflect-R1

Model checkpoints for **Reflect-R1: Evidence-Driven Reflection for Self-Correction in Long Video Understanding**.

- Paper: https://arxiv.org/abs/2606.27922
- Code: https://github.com/ShuimuChen-hyq/Reflect-R1
- Data: https://huggingface.co/datasets/CSDDSFSFSAFSAF/Reflect-R1-data

## Checkpoints

```text
Reflect-R1-SFT-6000/       Cold-start SFT checkpoint.
Reflect-R1-GRPO-Final/     Final SD-GRPO checkpoint.
```

Both checkpoints are based on Qwen2.5-VL-7B and include sharded `safetensors` weights together with the corresponding tokenizer and processor configuration files.
