SimpleStream

Paper: A Simple Baseline for Streaming Video Understanding Project: SimpleStream Code: EvolvingLMMs-Lab/SimpleStream Core Idea SimpleStream is a deliberately simple streaming baseline: when a question arrives, keep only the most recent N observed frames and feed them with the question to an off-the-shelf VLM. It uses: 1 fps sampling under the observed-only streaming protocol; a short recent-frame window, usually 2 / 4 / 8 frames; Qwen2.5-VL-7B or Qwen3-VL-8B as the base VLM; no new memory bank; no retrieval module; no KV cache compression; no extra training. So this is not a new architecture. It is a strong recency baseline for asking whether complex streaming memory is actually helping. ...
