# MathCoder-VL: Bridging Vision and Code for Enhanced Multimodal Mathematical Reasoning

Repo: [https://github.com/mathllm/MathCoder](https://github.com/mathllm/MathCoder)

Paper: [https://huggingface.co/papers/2505.10557](https://huggingface.co/papers/2505.10557)

## Introduction
We introduce MathCoder-VL, a series of open-source large multimodal models (LMMs) specifically tailored for general math problem-solving. We also introduce [FigCodifier-8B](https://huggingface.co/MathLLMs/FigCodifier), an image-to-code model.

| Base Model                                          	|Ours                                               |
