# IVT-LR

## Overview

This model was presented in the paper [Reasoning in the Dark: Interleaved Vision-Text Reasoning in Latent Space](https://huggingface.co/papers/2510.12603).

Interleaved Vision-Text Latent Reasoning (IVT-LR) is the first VLM framework that unifies textual and visual representations in the latent space and implements multimodal latent reasoning. Specifically, IVT-LR represents each reasoning step by combining two implicit parts: **latent text** and **latent vision**. We further introduce a progressive multi-stage training strategy to enable MLLMs to perform the above multimodal latent reasoning steps.

## Usage

This repository provides pretrained models for **Qwen2-VL on M3CoT** and **Chameleon on ScienceQA**.  

To see detailed usage, including inference code and scripts for training, please refer to the [GitHub repository](https://github.com/FYYDCC/IVT-LR).
