We release InternViT-6B-448px-V1-0, which is integrated into [InternVL-Chat-V1-1](https://huggingface.co/OpenGVLab/InternVL-Chat-V1-1). In this update, we explored increasing the resolution to 448x448, enhancing Optical Character Recognition (OCR) capabilities, and improving support for Chinese conversations. For examples of the enhanced capabilities, please refer to the [LINK](https://huggingface.co/OpenGVLab/InternVL-Chat-V1-1#examples).

## Model Details
- **Model Type:** vision foundation model, feature backbone
- **Model Stats:**
  - Params (M): 5903
  - Image size: 448 x 448
- **Pretrain Dataset:** LAION-en, LAION-COCO, COYO, CC12M, CC3M, SBU, Wukong, LAION-multi, OCR-related datasets.
- **Note:** This model has 48 blocks, and we found that using the output after the fourth-to-last block worked best for MLLM. Therefore, when building a MLLM with this model, **please use the features from the fourth-to-last layer.**

## Quick Start

> \[!Warning\]
> 🚨 Note: In our experience, the InternViT V2.5 series is better suited for building MLLMs than traditional computer vision tasks.

```python
import torch
from PIL import Image
from transformers import AutoModel, CLIPImageProcessor

model = AutoModel.from_pretrained(
    'OpenGVLab/InternViT-6B-448px-V1-0',
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True).cuda().eval()

image = Image.open('./examples/image1.jpg').convert('RGB')

image_processor = CLIPImageProcessor.from_pretrained('OpenGVLab/InternViT-6B-448px-V1-0')

pixel_values = image_processor(images=image, return_tensors='pt').pixel_values
pixel_values = pixel_values.to(torch.bfloat16).cuda()

outputs = model(pixel_values)
```
