我们发布了InternViT-6B-448px-V1-0，该模型已集成到InternVL-Chat-V1-1中。在此次更新中，我们探索了将分辨率提升至448x448，增强了光学字符识别（OCR）能力，并改进了对中文对话的支持。有关增强功能的示例，请参阅链接。

模型详情

• 模型类型: 视觉基础模型，特征骨干网络
• 模型统计:
  • 参数（百万）: 5903
  • 图像尺寸: 448 x 448
• 预训练数据集: LAION-en, LAION-COCO, COYO, CC12M, CC3M, SBU, Wukong, LAION-multi, OCR相关数据集。
• 注意: 该模型包含48个块，我们发现使用倒数第四块的输出对于MLLM效果最佳。因此，在构建MLLM时，请使用倒数第四层的特征。

[!警告] 🚨 注意：根据我们的经验，InternViT V2.5系列更适合构建MLLM，而非传统的计算机视觉任务。
