A Google-led team introduced StreamVibe, a proactive video-understanding agent that decides each second whether to offer spoken guidance.

StreamVibe aims to address over-talking and poor timing in video assistants. Its StreamVibe-VL model uses reinforcement learning to encourage restraint and memory to track unfinished requests and completed steps. One account of the tests says Gemini 3.8 Flash scored higher on some measures, while all models struggled to time help in videos longer than five minutes.
