+# SynLogic-7B: Logical Reasoning Model
+
+* 🐙 **GitHub Repo:** [https://github.com/MiniMax-AI/SynLogic](https://github.com/MiniMax-AI/SynLogic)
+* 📜 **Paper (arXiv):** [https://arxiv.org/abs/2505.19641](https://arxiv.org/abs/2505.19641)
+* 🤗 **Dataset:** [SynLogic on Hugging Face](https://huggingface.co/datasets/MiniMaxAI/SynLogic)
+
+## Model Overview
+
+**SynLogic-7B** is a logical reasoning model built on Qwen2.5-7B-Base and trained using reinforcement learning on our SynLogic dataset. Despite its smaller size, the model demonstrates strong logical reasoning capabilities and effective generalization to mathematical domains.
+
+## Key Features
+
+* **Comprehensive Logical Reasoning:** Trained on 27 diverse logical reasoning tasks (adapted for 7B scale) including Sudoku, Game of 24, Cipher, and more
+* **Verifiable Training:** All training data can be automatically verified, enabling effective reinforcement learning
+* **Strong Generalization:** Transfers logical reasoning skills to mathematical problem-solving without explicit math training
+* **Efficient Scale:** Achieves strong performance with a more compact 7B parameter model
+
+## Performance Highlights

+### Logical Reasoning Benchmarks
+| Model | KOR-Bench | BBH | BBEH |
+|-------|-----------|-----|------|
+| Qwen2.5-7B-Instruct | 38.6 | 62.7 | 12.4 |
+| **SynLogic-7B** | **48.1** | **66.5** | 8.0 |
+
+### Mathematical Benchmarks
+| Model | AIME 2024 | MATH 500 | AMC 2023 |
+|-------|-----------|----------|----------|
+| Qwen2.5-7B-Base | 0.3 | 64.6 | 30.0 |
+| Qwen2.5-7B-Instruct | 6.3 | 76.4 | 52.5 |
+| **SynLogic-7B** | **10.0** | 71.8 | **55.0** |
+
+**Key Achievements:**
