Summary
This paper talks about ReTool, a new system that helps language models get better at solving structured problems, like math, by letting them use tools and learn from their actions using reinforcement learning.
What's the problem?
The problem is that while language models can answer lots of questions, they often struggle with tasks that require step-by-step reasoning or using external tools, such as running code to check their answers. This limits how well they can solve complex problems, especially in subjects like math or science.
What's the solution?
The researchers created ReTool, which allows language models to actually use tools like code execution while they're working on a problem. By using reinforcement learning, the model gets feedback and learns which actions help it solve problems more accurately. This makes the model much better at handling structured and logical tasks.
Why it matters?
This matters because it means AI can now tackle more complicated problems that need careful reasoning and real-world tool use, making it much more useful for students, teachers, and professionals who need help with tough subjects.
Abstract
ReTool, a tool-integrated learning framework, enhances reasoning models with real-time code execution and reinforcement learning, significantly improving performance in structured problem-solving tasks like mathematical reasoning.
