What InternVL3 does
InternVL3 is an open source family of multimodal large language models from the OpenGVLab team that understand images, video and text together. It is aimed at researchers and developers building vision language applications. The series spans sizes from InternVL3-1B to InternVL3-78B and uses a ViT-MLP-LLM design with native multimodal pre-training, Variable Visual Position Encoding for longer contexts and Mixed Preference Optimization for reasoning. It supports dynamic resolution image tiling, multi-image and video input, tool use, GUI agents, OCR and document understanding, and 3D vision perception, with a VisualPRM reward model for test time scaling. Models are free to download from Hugging Face and ModelScope.
