We released InternVL-Chat-V1-1, featuring a structure similar to LLaVA, including a ViT, an MLP projector, and an LLM. In this version, we explored increasing the resolution to 448x448, enhancing OCR capabilities, and improving support for Chinese conversations.

## Model Details
- **Model Type:** multimodal large language model (MLLM)
- **Model Stats:**
  - Architecture: [InternViT-6B-448px](https://huggingface.co/OpenGVLab/InternViT-6B-448px) + MLP + LLaMA2-13B (Our internal SFT versions)
  - Image size: 448 x 448 (256 tokens)
  - Params: 19B

- **Training Strategy:**
  - Pretraining Stage
    - Learnable Component: InternViT-6B + LLaMA2-13B
    - Data: Trained on 72M samples, including COYO, LAION, CC12M, CC3M, SBU, Wukong, GRIT, Objects365, OpenImages, and OCR-related datasets.
    - Note: In this stage, we load the pretrained weights of the original [InternViT-6B-224px](https://huggingface.co/OpenGVLab/InternViT-6B-224px) and interpolate its position embedding to the size corresponding to 448 x 448 pixels. Moreover, in order to reduce the number of visual tokens, we use a pixel shuffle operation to reduce 1024 tokens to 256 tokens.
  - Supervised Finetuning Stage
    - Learnable Component: MLP + LLaMA2-13B
    - Data: A comprehensive collection of open-source datasets, along with their Chinese translation versions, totaling approximately 6M samples.

## Model Usage

We provide an example code to run InternVL-Chat-V1-1 using `transformers`.

You also can use our [online demo](https://internvl.opengvlab.com/) for a quick experience of this model.

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

path = "OpenGVLab/InternVL-Chat-V1-1"
# If your GPU has more than 40G memory, you can put the entire model on a single GPU.
model = AutoModel.from_pretrained(
    path,
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True).eval().cuda()
# Otherwise, you need to set device_map='auto' to use multiple GPUs for inference.
# model = AutoModel.from_pretrained(
#     path,
#     torch_dtype=torch.bfloat16,
#     low_cpu_mem_usage=True,
#     trust_remote_code=True,
#     device_map='auto').eval()

tokenizer = AutoTokenizer.from_pretrained(path)
image = Image.open('./examples/image2.jpg').convert('RGB')
image = image.resize((448, 448))
image_processor = CLIPImageProcessor.from_pretrained(path)

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

generation_config = dict(
    num_beams=1,
    max_new_tokens=512,
    do_sample=False,
)

# single-round conversation
question = "请详细描述图片"
response = model.chat(tokenizer, pixel_values, question, generation_config)
print(question, response)

# multi-round conversation
question = "请详细描述图片"
response, history = model.chat(tokenizer, pixel_values, question, generation_config, history=None, return_history=True)
print(question, response)

question = "请根据图片写一首诗"
response, history = model.chat(tokenizer, pixel_values, question, generation_config, history=history, return_history=True)
print(question, response)
```

## Examples

In this update, InternVL-Chat has **improved support for Chinese and OCR**.

As you can see, although the Lynyrd Skynyrd in the image has some letters that are out of the camera's lens, and TOUR's T is blocked, the model is still able to recognize it correctly.

This model can also conduct an in-depth analysis of AAAI's official website and identify important information on the web page.
