| # 🚀 GRPO-LEAD: Efficient Reasoning Enhancement for Mathematical Tasks |
|
|
| --- |
|
|
| ## 📚 Overview |
|
|
| **GRPO-LEAD** (**GRPO** with **L**ength-dependent rewards, **E**xplicit penalties, and **A**dvantage reweighting for **D**ifficulty) is an advanced reinforcement learning pipeline designed to fine-tune large language models (LLMs) for concise, accurate, and efficient reasoning in mathematical tasks. |

|
|
| ## 📊 Performance Benchmarks |
|
|
| The following benchmarks were conducted on AIME24 and AIME25 datasets, evaluated with parameters: 14k maximum tokens, temperature of 0.6, min-p of 0.01, and 32 samples per question. |
|
|
| | **Model** | **AIME24 Cons@32** | **AIME24 Pass@1** | **AIME24 Avg. Length** | **AIME25 Cons@32** | **AIME25 Pass@1** | **AIME25 Avg. Length** | |
| |---------------------|--------------------|-------------------|------------------------|--------------------|-------------------|------------------------| |
| | **DeepSeek-Distlled-14B** | 0.800 | 0.614 | 9182 | 0.633 | 0.429 | 10046 | |
| | **Light-R1-14B-DS** | 0.833 | 0.641 | 9571 | 0.767 | 0.505 | 10194 | |
| | **LEAD-14B (ours)** | **0.867** | **0.650** | **8267** | **0.767** | **0.539** | **8668** | |
|
|
| Our GRPO-LEAD model achieves superior consistency and higher accuracy, demonstrating significantly improved reasoning efficiency as evidenced by shorter average reasoning lengths. |

| ## ⚙️ Usage |
|
|
| To achieve the best performance in solving mathematical problems, simply use the following prompt format: |
| ```python |
| [ |
| { |
| "role": "user", |
| "content": question + "\nLet's think step by step and output the final answer within \\boxed{}." |
| } |
| ] |
| ``` |

| ## 📦 Dataset: GRPO-LEAD-SFTData |
|
|
| We release [**GRPO-LEAD-SFTData**](https://huggingface.co/datasets/PlanePaper/GRPO-LEAD-SFTData), a curated collection of **12,153** high-quality mathematical reasoning samples for supervised fine-tuning. Generated via [**QwQ-32B**](https://huggingface.co/Qwen/QwQ-32B). |
| Derived primarily from the **DeepScaler** dataset ([DeepScaler](https://github.com/agentica-project/rllm)), we retain only examples with **difficulty > 1**, targeting challenging problem-solving scenarios. All entries are structured for seamless integration with [**LLaMA Factory**](https://github.com/hiyouga/LLaMA-Factory) and follow a standardized SFT-ready format. |
|
|
| Used as the training data for GRPO-LEAD’s supervised fine-tuning stage, this dataset is able to increase the model's base capability in solving mathematical problems., |
