From Perception to Prediction and Intervention: Benchmarking Proactive Video Assistants in Real-Life Scenarios

The paper introduces “P…IBench”, a benchmark for proactive video understanding that tests daily perception, risk prediction, and intervention in real‑life streaming scenarios. It evaluates 12 video‑language models, finding that current systems struggle to make well‑calibrated response decisions. The authors also create new proactive training data and train “P…I-Assistant-4B”, which shows uneven improvements across the benchmark’s capabilities.
