Model Card for InternVL-Chat-Chinese-V1.1
What is InternVL?
InternVL scales up the ViT to 6B parameters and aligns it with LLM.
Model Details
Model Type: multimodal large language model (MLLM)
Model Stats:
- Architecture: 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 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.
- Pretraining Stage
Model Usage
We provide a minimum code example to run InternVL-Chat using only the transformers library.
You also can use our online demo for a quick experience of this model.
Note: If you meet this error ImportError: This modeling file requires the following packages that were not found in your environment: fastchat, please run pip install fschat.

# single-round conversation

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.
