  • 2024.11.11: Mono-InternVL is supported by lmdeploy
  • 2024.11.3: Mono-InternVL is supported by vllm.

Introduction

We release Mono-InternVL, a monolithic multimodal large language model (MLLM) that integrates visual encoding and textual decoding into a single LLM. In Mono-InternVL, a set of visual experts is embedded into the pre-trained LLM via a mixture-of-experts (MoE) mechanism. By freezing the LLM, Mono-InternVL ensures that visual capabilities are optimized without compromising the pre-trained language knowledge. Based on this structure, an innovative Endogenous Visual Pretraining (EViP) is introduced to realize coarse-to-fine visual learning.

Mono-InternVL achieves superior performance compared to state-of-the-art MLLM Mini-InternVL-2B-1.5 and significantly outperforms other monolithic MLLMs, as shown in the radar chart above. Meanwhile, it achieves better deployment efficiency, with first token latency reduced by up to 67%.

This repository contains the instruction-tuned Mono-InternVL-2B model, which has 1.8B activated parameters (3B in total). It is built upon internlm2-chat-1_8b. For more details, please refer to our paper.

  • Sources of the results include the original papers, our evaluation with VLMEvalKit, and OpenCompass.
  • Average scores are computed by normalizing each metric to a range between 0 and 100.
  • Please note that evaluating the same model using different testing toolkits can result in slight differences, which is normal. Updates to code versions and variations in environment and hardware can also cause minor discrepancies in results.

Limitations: Although we have made efforts to ensure the safety of the model during the training process and to encourage the model to generate text that complies with ethical and legal requirements, the model may still produce unexpected outputs due to its size and probabilistic generation paradigm. For example, the generated responses may contain biases, discrimination, or other harmful content. Please do not propagate such content. We are not responsible for any consequences resulting from the dissemination of harmful information.

Quick Start

We provide an example code to run Mono-InternVL-2B inference using transformers.

Please use transformers==4.37.2 to ensure the model works normally.

简介

我们发布了Mono-InternVL，这是一种原生多模态大语言模型，将视觉编码和文本解码集成到一个单一的大语言模型中。在Mono-InternVL中，一组视觉专家通过专家混合机制嵌入到预训练的语言模型中。通过冻结语言模型的语言部分参数，Mono-InternVL确保了视觉能力的优化，同时不会影响预训练的语言知识。基于这一结构，我们引入了内生视觉预训练（Endogenous Visual Pretraining, EViP），实现了由粗粒度到精粒度的视觉学习。

Mono-InternVL在性能上优于当前最先进的多模态语言模型Mini-InternVL-2B-1.5，并且显著超越了其他原生多模态模型，如上方的雷达图所示。同时，它的部署效率也得到了提升，首个单词的延迟降低了最多达67%。

本仓库包含了经过指令微调的Mono-InternVL-2B模型，它是基于internlm2-chat-1_8b搭建的。更多详细信息，请参阅我们的论文和公众号报道。
