Model Card for InternVL3Fangwusha2B

InternVL3Fangwusha2B is a 2B-parameter vision-language model (VLM) fine-tuned from InternVL3-2B, optimized for Chinese multimodal understanding, image-text interaction, document analysis, and visual content reasoning in practical application scenarios.

Model Details

Model Description

This model is a lightweight multimodal large model based on the InternVL3-2B architecture, focusing on improving Chinese image-text alignment, visual question answering, document OCR + understanding, and daily scene multimodal interaction. It provides efficient inference while maintaining strong multimodal capabilities.

Uses

Direct Use

This model can be directly used for:

• Chinese visual question answering (VQA)
• Image captioning and description generation
• Document image analysis (tables, forms, scanned files)
• OCR-assisted text understanding from images
• Daily scene multimodal dialogue and information extraction

Downstream Use [optional]

Can be further fine-tuned for:

• Enterprise document intelligent processing systems
• Educational image-text question answering
• E-commerce product image understanding
• Mobile-side lightweight multimodal assistants
• RAG systems combined with visual information

Out-of-Scope Use

• Not designed for high-risk visual decision-making (medical imaging, autonomous driving, industrial detection without professional review)
• Not suitable for generating harmful, illegal, pornographic, or privacy-violating multimodal content
• Not optimized for non-Chinese languages
• Not intended for ultra-high-resolution image analysis beyond its input constraints

Bias, Risks, and Limitations

• The model may inherit social, cultural, and visual biases present in the pre-trained InternVL3 and public image-text datasets.
• It may produce visual hallucinations, misrecognize objects, or generate inconsistent descriptions for blurry, low-light, or highly abstract images.
• Performance on specialized professional images (medical, remote sensing, microscopic) is limited without domain fine-tuning.
• The model does not have autonomous fact-checking and may generate factually incorrect multimodal responses.

Recommendations

All outputs in professional or production scenarios should be verified by humans. Visual inputs with sensitive or private information require appropriate filtering and protection. It is recommended to access professional modules for high-precision visual tasks. Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.

How to Get Started with the Model

Use the code below to get started with the model.

from transformers import AutoModel, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained(model_name)

# Example image-text interaction
# image = load_image("your_image.jpg")
# response = model.chat(tokenizer, image, "请描述这张图片的内容")
# print(response)
