What it does

Benchmark video Q&A accuracy and latency of a deployed RT-VLM (Cosmos Reason 3) via vss vlm run, using questions and videos from the DSS vss-devx-base dataset. Replaces the deprecated nat eval / vss-agent QA path. Not for tool-calling or trajectory evaluation, and not for LVS summarization throughput.

Benchmark video Q&A via vss vlm

Measure accuracy (LLM-as-judge vs ground truth) and latency of end-to-end video question answering by calling vss vlm run against a deployed Cosmos Reason 3 RT-VLM. Questions and clips come from DSS dataset vss-devx-base (nvdataset).

This replaces docker exec vss-agent nat eval for the QA slice. It does not score tool-calling or trajectories.

When to use

  • The user asks to benchmark / evaluate VLM video Q&A after vss-agent / NAT eval was removed.
  • The user wants latency and answer accuracy on vss-devx-base.

When not to use

  • Tool-calling or trajectory evaluation, out of scope.
  • LVS summarization throughput, use vss-benchmark-video-summarization.
  • Ad-hoc single questions, use /vss-ask-video.

Prerequisites

  • A VSS stack with RT-VLM serving Cosmos Reason 3, and vss configure already run so vss configure check lists rt_vlm as ok and vst as ok.
