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

Repo: https://github.com/mathllm/MathCoder

Paper: 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, an image-to-code model.

Base Model	Ours
Mini-InternVL-Chat-2B-V1-5	MathCoder-VL-2B
InternVL2-8B	MathCoder-VL-8B
InternVL2-8B	FigCodifier-8B

Usage

For training and inference code, please refer to InternVL.

from datasets import load_dataset
from PIL import Image
from io import BytesIO

mm_mathinstruct = load_dataset("MathLLMs/MM-MathInstruct")
print(mm_mathinstruct)

# show the last image
img = Image.open(BytesIO(mm_mathinstruct['train'][-1]['image']))
img.show()

It should print:

DatasetDict({
    train: Dataset({
        features: ['id', 'image', 'question', 'solution', 'image_path'],
        num_rows: 2871988
    })
})

Prompt for TikZ Code Generation

<image>\nPlease generate the corresponding TikZ code that accurately represents the visual elements in the image. TikZ is a powerful tool for creating vector graphics within LaTeX documents. Your generated code should be precise, well-structured, and should recreate the image as faithfully as possible.

Prompt for Python Code Generation

Please provide the Python code needed to reproduce this image.\n<image>
