 # InternVL2.5
 ## 论文

 [Expanding Performance Boundaries of Open-Source Multimodal Models with Model, Data, and Test-Time Scaling](https://arxiv.org/abs/2412.05271)
 
-
-## 模型结构
-InternVL 2.5保留了与InternVL 1.5[35]相同的模型架构，并且
-InternVL 2.0，即广泛使用的“ViT-MLP-LLM”范式，结合了预先训练的InternViT-300M
-或通过MLP投影仪具有各种尺寸的LLM[19，229]的InternViT-6B。与之前的版本一致，
-我们应用像素反洗牌操作来减少每个448 × 448图像块产生的1024个视觉令牌
-到256个代币。此外，与InternVL 1.5相比，InternVL 2.0和2.5引入了额外的数据类型，
-将多图像和视频数据与现有的单图像和纯文本数据合并。

+## 模型简介
+InternVL 2.5 保留了与前代模型 InternVL 1.5 和 2.0 相同的模型架构，遵循“ViT-MLP-LLM”范式。在新版本中，使用随机初始化的 MLP 投影器集成了一个新增量预训练的 InternViT 与各种预训练 LLM（包括 InternLM 2.5 和 Qwen 2.5）。
+正如之前的版本一样，应用了像素解混操作，将视觉标记的数量减少到原来的四分之一。此外，采用了与InternVL 1.5类似的动态分辨率策略，将图像分割成448×448像素的块。从InternVL 2.0开始的关键区别在于，额外引入了对多图像和视频数据的支持。

-## 算法原理
-
-InternVL 2.5训练过程分为三个阶段——阶段1（MLP预热）可选阶段1.5（ViT增量学习）和阶段2（全模型指令调优）。多阶段设计逐步增强视觉-语言对齐，稳定培训，并为与更大的LLM集成准备模块。(b)逐步扩大战略。在早期阶段用较小的LLM训练的ViT模块可以很容易地与较大的LLM集成，以可承受的资源开销实现可扩展的模型对齐。

-## 环境配置
-### Docker（方法一）
-推荐使用docker方式运行， 此处提供[光源](https://www.sourcefind.cn/#/service-details)拉取docker镜像的地址与使用步骤
-```
