Model Overview

SynLogic-32B is a state-of-the-art reasoning model built on Qwen2.5-32B-Base and trained using reinforcement learning on our comprehensive SynLogic dataset. The model excels at logical reasoning tasks and demonstrates strong generalization to mathematical domains.

Key Features

• Comprehensive Logical Reasoning: Trained on 35 diverse logical reasoning tasks including Sudoku, Game of 24, Cipher, Arrow Maze, 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

Performance Highlights

Key Achievement: +6 points improvement over DeepSeek-R1-Distill-Qwen-32B on the challenging BBEH benchmark, establishing state-of-the-art performance among open-source logical reasoning models.

Training Details

• Base Model: Qwen2.5-32B-Base
• Training Algorithm: GRPO (Group Relative Policy Optimization)
• Dataset: 33k SynLogic-Hard samples with controlled difficulty
• Reward Design: Binary rewards based on format adherence and correctness verification
