Streaming video understanding is not only about what a model answers, but also about when it answers. The arXiv abstract for PACE notes that evidence arrives progressively, and recent benchmarks identify premature responses—answers issued before the queried event has occurred.
To address this, the paper introduces PACE, which stands for Plan, Attend, Check, and Emit. The method is described as training-free, meaning it does not require additional fine-tuning of the underlying video model.
The announcement is brief and does not include experimental results or implementation details. It frames PACE as a response-timing mechanism for streaming video, but the available text does not specify how each component works or how the method compares to alternatives.
