Model Card

InternVL3 78B is an open-source multimodal large language model developed by OpenGVLab, combining a 6B vision transformer with a 72.7B Qwen2.5 language backbone. It is the flagship of the InternVL3 series and achieves state-of-the-art performance among open-source multimodal models.

The model excels at visual reasoning, document understanding, OCR, chart interpretation, and video comprehension. On the MMMU benchmark it scores 72.2%, surpassing GPT-4o (70.7%), and on MathVista it reaches approximately 79.0 compared to GPT-4o's 63.8. It also achieves an OCRBench score of 906.

A key differentiator is its native multimodal pre-training approach, which trains vision and language capabilities together from the start rather than retrofitting vision onto a text-only model. This actually improves text performance over the base Qwen2.5, making it a strong choice for developers who need both visual and textual reasoning in a single model with a 32,768-token context window.
