## Overview
This repository provides **steering vectors only** for ReBalance.

It does **not** include:
- base model weights,
- inference/training code,
- datasets.

Use this repository together with the official codebase:
- Code: https://github.com/yu-lin-li/ReBalance
- Inference script: `transformer_inference_steer_dp.py`

## Available Steering Vectors
| Base model | Vector path | Recommended `--steer_layer` |
|---|---|---|
| DeepSeek-R1-Distill-Qwen-1.5B | `vectors/DeepSeek-R1-Distill-Qwen-1.5B/steer_vector_layer19_conf_mixed.pt` | `19` |
| DeepSeek-R1-Distill-Qwen-7B | `vectors/DeepSeek-R1-Distill-Qwen-7B/steer_vector_layer22_conf_mixed.pt` | `22` |
| QwQ-32B | `vectors/QwQ-32B/steer_vector_layer58_conf_mixed.pt` | `58` |

## Local Directory Layout (after download)
```text
ReBalance/
├── transformer_inference_steer_dp.py
└── vectors/
    ├── DeepSeek-R1-Distill-Qwen-1.5B/
    │   └── steer_vector_layer19_conf_mixed.pt
    ├── DeepSeek-R1-Distill-Qwen-7B/
    │   └── steer_vector_layer22_conf_mixed.pt
    └── QwQ-32B/
        └── steer_vector_layer58_conf_mixed.pt
```

## Download
### Option 1: Clone the full model repository
```bash
git lfs install
git clone https://huggingface.co/Yulin-Li/ReBalance
```

Then copy the `vectors/` folder into your local `ReBalance/` root directory.

### Option 2: Download only the vectors with `huggingface_hub`
```python
from huggingface_hub import snapshot_download

snapshot_download(
    repo_id="Yulin-Li/ReBalance",
    repo_type="model",
    allow_patterns="vectors/*",
    local_dir="."
)
```

## Quick Usage with ReBalance
```bash
python transformer_inference_steer_dp.py \
  --model_name_or_path 'DeepSeek-R1-Distill-Qwen-1.5B' \
  --dataset_dir "./Data/" \
  --output_path "./outputs" \
  --dataset "Math_AIME2024" \
  --max_generated_tokens 16000 \
  --num_gpus 8 \
  --steer_vector_path ./vectors/DeepSeek-R1-Distill-Qwen-1.5B/steer_vector_layer19_conf_mixed.pt \
  --steer_layer 19 \
  --steer_coef -1
```
