TwiFF (Think With Future Frames): A Large-Scale Dataset for Dynamic Visual Reasoning

🧠 Method

We present TwiFF, a unified model fine-tuned on a high-quality dynamic visual Chain-of-Thought (VCoT) dataset comprising 2.7 million samples. In dynamic multimodal question-answering tasks involving instructional, predictive, and camera, TwiFF iteratively generates future event frames alongside textual reasoning, thereby producing temporally coherent visual reasoning trajectories. Experimental results demonstrate that, on dynamic scenario reasoning benchmarks, our dynamic VCoT approach outperforms both static VCoT methods based on tool-calling paradigms and purely textual chain-of-thought baselines.
