Microsoft's rStar-Math aims to enhance small language models' math reasoning by:
β‘οΈ using System 2-style deep thinking (careful analysis and step-by-step reasoning).
β‘οΈ Monte Carlo Tree Search and self-evolution to generate high-quality training data.
It appears to achieve 90% accuracy on the MATH dataset and gets close to larger models, making advanced AI more accessible.

Microsoft AI Introduces rStar-Math: A Self-Evolved System 2 Deep Thinking Approach that Significantly Boosts the Math Reasoning Capabilities of Small LLMs
Mathematical problem-solving has long been a benchmark for artificial intelligence (AI). Solving math problems accurately requires not only computational precision but also deep reasoningβan area where even advanced language models (LLMs) have traditionally faced challenges. Many existing models rely on what psychologists term 'System 1 thinking,' which is fast but often prone to errors. This approach generates solutions in a single inference, bypassing the iterative reasoning process essential for tackling complex problems. Furthermore, training high-quality models relies on curated datasets, which are particularly scarce for competition-level math problems. Open-source methods frequently fail to exceed the capabilities of their 'teacher' models,
