LongVT: Incentivizing "Thinking with Long Videos" via Native Tool Calling

arXiv — cs.CVThursday, November 27, 2025 at 5:00:00 AM
  • LongVT has been introduced as an innovative framework designed to enhance video reasoning capabilities in large multimodal models (LMMs) by utilizing a method termed 'Thinking with Long Videos.' This approach allows for a more effective analysis of long-form videos by interleaving global and local reasoning processes, ultimately improving the accuracy of video-based question answering.
  • The development of LongVT is significant as it addresses the challenges of hallucinations in LMMs, particularly when dealing with long videos where relevant information is often sparse. By leveraging a native video cropping tool, LongVT aims to ground answers in visual evidence, thereby enhancing the reliability of video reasoning tasks.
  • This advancement aligns with ongoing efforts in the AI community to improve multimodal reasoning and question-answering systems. Similar frameworks, such as SFA and CounterVQA, also focus on refining video understanding and reasoning capabilities, highlighting a broader trend towards enhancing AI's ability to process and interpret complex visual and textual information.
