CodePlot-CoT: Mathematical Visual Reasoning by Thinking with Code-Driven Images

This repository contains the CodePlot-CoT model, a core component of the paper CodePlot-CoT: Mathematical Visual Reasoning by Thinking with Code-Driven Images. CodePlot-CoT is an innovative code-driven Chain-of-Thought (CoT) paradigm designed to enable Vision Language Models (VLMs) to "think with images" when solving mathematical problems. Instead of generating pixel-based images directly, the model outputs executable plotting code to represent its "visual thoughts". This code is then executed to render a precise figure, which is reinput to the model as a visual input for subsequent reasoning steps.

The model is built upon the Qwen2.5-VL architecture and is compatible with the transformers library.
