Multimodal large language models (MLLMs) have advanced in processing visual, text, and audio data, improving applications like document analysis and video comprehension. However, they often struggle to accurately identify and track objects, scenes, and movements in complex videos, which can be frustrating for users. To address this, researchers at the Shanghai AI Laboratory have developed InternVideo2.5, which is built upon their InternVL2.5 model.
This new model improves how videos are processed by capturing more details and understanding longer sequences, making it better at recognizing complex video content. InternVideo2.5 can improve existing MLLMs with notable performance in video understanding as well as granting them expert-level visual perception abilities.

Technical Innovations Behind InternVideo2.5
1. Long and Rich Context (LRC) Modeling
The core innovation of InternVideo2.5 lies in its Long and Rich Context (LRC) modeling. This approach focuses on enhancing the model’s ability to perceive and interpret multimodal inputs over extended periods. By addressing the length and detail of the context, InternVideo2.5 significantly improves its understanding of complex narratives and interactions within videos.
2. Direct Preference Optimization
InternVideo2.5 employs Direct Preference Optimization to incorporate dense vision task annotations into its processing framework. This method enables the model to learn from high-quality visual data more effectively, enhancing its overall performance.
3. Compact Spatiotemporal Representations
Through adaptive hierarchical token compression (HiCo), InternVideo2.5 creates compact representations of spatiotemporal data. This technique allows the model to efficiently process long visual signals while preserving essential details efficiently, thus enhancing its interpretative capabilities.
Performance Benchmarks and Achievements
InternVideo2.5 has been rigorously tested against various benchmarks, consistently outperforming state-of-the-art (SOTA) models. InternVideo2.5 achieves leading performance on MVBench and VideoMME, demonstrating its exceptional ability to comprehend complex video content. Its ability to handle longer video sequences while maintaining high accuracy in object recognition and temporal understanding sets it apart from its competitors.
While models like GPT4-o achieved a score of 64.6 on MVBench, InternVideo2.5 surpassed this with a score of 75.7. Furthermore, proprietary models like Gemini-1.5-Pro and LLaVA-OneVision also fall behind in several benchmarks. The model’s performance demonstrates its potential to revolutionize the field of video analysis.
Potential Applications of InternVideo2.5
