# DylanDeep-Core-8B-DPO

A math reasoning model achieving **84.84% on GSM8K** through preference optimization.

## Model Details

- **Base**: Abel-7B-002 (LLaMA-2 architecture)
- **Method**: SFT + DPO with counterfactual reasoning
- **Evaluation**: 8-shot majority voting

## Performance

| Model | GSM8K Accuracy |
|-------|----------------|
| Abel-7B-002 (base) | 79.08% |
| + SFT | 84.46% |
| + DPO | **84.84%** |

## Training

Fine-tuned with LoRA adapters using a two-stage approach:
1. Supervised fine-tuning on GSM8K training set
2. DPO on 3,334 preference pairs with counterfactual probing
   

## Training Code

[DylanDeep-Core-8B-DPO](https://github.com/dmilstein-match/DylanDeep-Core-8B-DPO)

## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("dylxnmyl/DylanDeep-Core-8B-DPO")
tokenizer = AutoTokenizer.from_pretrained("dylxnmyl/DylanDeep-Core-8B-DPO")
