Aligned Multi-View Scripts for Universal Chart-to-Code Generation

CharLuMA-6.7B generates a plotting script in Python, R, or LaTeX from a chart image. This 6.7B variant is from the paper "Aligned Multi-View Scripts for Universal Chart-to-Code Generation" (ACL 2026 Main Conference).

Paper: https://arxiv.org/abs/2604.24559
Code (required for inference): https://github.com/zhihan72/CharLuMA
1.3B Variant: CharLuMA-1.3B
Training data: Chart2NCode

Backbone	Vision encoder	Output languages	dtype
DeepSeek-Coder-6.7B-Instruct	SigLIP-SO400M-patch14-384	Python, R, LaTeX	bfloat16

Usage

This is a custom architecture, so AutoModel.from_pretrained will not load it.

Clone the codebase and use its loader:

git clone https://github.com/Zhihan72/CharLuMA

Before loading, replace the placeholder paths in config.json (/your_local_path/...) with deepseek-ai/deepseek-coder-1.3b-instruct (or a local copy) and google/siglip-so400m-patch14-384 (or a local copy).

Inference example: scripts/inference_charluma.py in the repo.
