Internvl2 8B MPO
Overview :
InternVL2-8B-MPO is a multimodal large language model (MLLM) that enhances multimodal inference capabilities by introducing a Mixed Preference Optimization (MPO) process. The model features an automated pipeline for preference data construction and builds the MMPR, a large-scale multimodal inference preference dataset. Based on the InternVL2-8B model, InternVL2-8B-MPO is fine-tuned using the MMPR dataset, demonstrating stronger multimodal inference capabilities with fewer hallucinations. The model achieved an accuracy of 67.0% on MathVista, surpassing the InternVL2-8B by 8.7 points, and performing closely to the much larger InternVL2-76B model.
Target Users :
The target audience includes researchers, developers, and enterprise users, especially those who need to handle multimodal data (such as images and text) and wish to enhance the inference capabilities of models. InternVL2-8B-MPO provides more accurate data analysis and generates more reliable results, making it suitable for improving product intelligence and supporting decision-making.
Use Cases
