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

Zuhao Yang, Sudong Wang, Kaichen Zhang +8

Large multimodal models (LMMs) have shown great potential for video reasoning with textual Chain-of-Thought. However, they remain vulnerable to hallucinations, especially when proc…
