<p>大型语言模型 (LLM) 的迅猛增长为多模态 AGI 系统开辟了无数可能性。然而，视觉和视觉语言基础模型（也是多模态 AGI 的关键要素）的进步却未能跟上 LLM 的步伐。在这项工作中，我们设计了一个大型视觉语言基础模型 (InternVL)，该模型将视觉基础模型扩展到 60 亿个参数，并逐步将其与 LLM 对齐，使用来自各种来源的网络规模图像文本数据。该模型可广泛应用于 32 个通用视觉语言基准测试，并在这些基准测试中取得最佳性能，包括视觉感知任务（例如图像级或像素级识别）、视觉语言任务（例如零样本图像/视频分类、零样本图像/视频文本检索），并与 LLM 链接以创建多模态对话系统。它具有强大的视觉功能，可以成为 ViT-22B 的良好替代品。</p>
