# DNA-R1

<p align="center">

</p>

We introduce **DNA-R1**, a specialized reasoning model optimized for Korean language based on Microsoft's Phi-4. By applying large-scale reinforcement learning (RL) using the same methodology as DeepSeek-R1, we have significantly enhanced the model's Korean reasoning capabilities. This model demonstrates deep understanding of Korean text and exhibits exceptional reasoning abilities across mathematics, coding, and general reasoning tasks.

</p>

## Training Methodology

Our comprehensive training pipeline consists of three strategic stages:

- **Stage 1:** Initial SFT with a large Korean non-reasoning dataset (760k examples) reused from our [DNA 1.0 8B Instruct](https://huggingface.co/dnotitia/Llama-DNA-1.0-8B-Instruct) training pipeline
- **Stage 2:** Strategic integration of Korean reasoning patterns from DeepSeek R1 using a specialized Korean reasoning dataset (300k examples)
- **Stage 3:** Advanced reinforcement learning with GRPO using a combined Korean/English reasoning dataset, with format, accuracy, and language consistency as rewards

DNA-R1 has learned reasoning patterns specifically tailored for Korean language, and demonstrates capabilities such as self-verification, reflection, and generation of long chains-of-thought (CoT). This represents a significant milestone for the AI research community in the Korean language environment.

## Technical Details

### Multi-Stage Training Pipeline

We implemented a sophisticated training approach to enhance Phi-4's Korean reasoning capabilities:

1. **Initial Foundation (Stage 1):** Supervised Fine-Tuning using our extensive Korean non-reasoning dataset from the established [DNA 1.0 8B Instruct](https://huggingface.co/dnotitia/Llama-DNA-1.0-8B-Instruct) training pipeline
2. **Reasoning Integration (Stage 2):** Specialized adaptation of DeepSeek R1's reasoning patterns with Korean-specific optimization through a meticulously curated dataset
3. **Advanced Refinement (Stage 3):** Reinforcement learning optimization using GRPO to perfect reasoning in both Korean and English, with comprehensive reward signals for format structure, factual accuracy, and language consistency

This methodical approach enables DNA-R1 to develop sophisticated chain-of-thought (CoT) reasoning for complex problem solving, resulting in a model finely calibrated for Korean language reasoning while maintaining robust general capabilities.

### Performance Highlights

Our Korean-specific multi-stage training pipeline significantly enhances the Phi-4 base model's understanding of Korean context, reasoning depth, and response capabilities. The model excels at:

- Generating nuanced Korean chains-of-thought (CoT)
- Performing rigorous self-verification
- Solving multi-step complex problems
- Maintaining cultural and linguistic context in reasoning
- Distinguishing between deep thinking and concise answers using the `<think>` and `<answer>` tags

## Evaluation Results

Below, we present our evaluation results for the DNA-R1 model across math, coding, science, Korean, and general-performance benchmarks.
Despite being only 14B in size, the DNA-R1 model demonstrates superior performance compared to many larger models across various benchmarks.

그러다 라면이 너무 지겨워서
맛있는 것 좀 먹자고 대들었었어
그러자 어머님이 마지못해 꺼내신
