Overview

• Light-R1 is a new 32B parameter language model specifically designed for long chain-of-thought reasoning
• Built using a curriculum approach combining Supervised Fine-Tuning (SFT), Direct Preference Optimization (DPO), and Reinforcement Learning (RL)
• Started training from scratch rather than building on existing models
• Achieves strong performance on complex reasoning benchmarks with long-form answers
• Demonstrates that systematic training rather than model size is key for reasoning capabilities

Plain English Explanation

Language models have gotten incredibly good at many tasks, but they still struggle with complex reasoning - especially when they need to work through problems step-by-step over long sequences. The researchers behind Light-R1 decided to tackle this challenge head-on.
