# Model Card for InternVL-14B-224px |
|
|
|
## What is InternVL? |
|
|
|
\[[Paper](https://arxiv.org/abs/2312.14238)\] \[[GitHub](https://github.com/OpenGVLab/InternVL)\] \[[Chat Demo](https://internvl.opengvlab.com/)\] |
|
|
|
InternVL scales up the ViT to _**6B parameters**_ and aligns it with LLM. |
|
|
|
It is _**the largest open-source vision/vision-language foundation model (14B)**_ to date, achieving _**32 state-of-the-art**_ performances on a wide range of tasks such as visual perception, cross-modal retrieval, multimodal dialogue, etc. |

## Model Usage |
|
|
|
**Note: the prefix `'summarize:'` and `tokenizer.pad_token_id = 0` are necessary. Their absence will lead to abnormal results.** |
|
|
|
```python |
|

|
from PIL import Image |
|
from transformers import AutoModel, CLIPImageProcessor |
|
