Visual Orchestration Tax in Agentic VLM Pipelines: Auditing and Certifying Visual Evidence Reuse

Read the original on arXiv Computer Vision →

The paper introduces the concept of a visual orchestration tax in agentic vision‑language model (VLM) pipelines, where the same static images are repeatedly processed by multiple agents, creating redundancy. It proposes a measurement‑to‑certification framework that audits visual evidence reuse using metrics M1_trace and M2, and certifies reuse through a SharedVisCache contract. Experiments on SeeingEye and MAMMQA show high redundancy rates (66.8‑75.6%) and demonstrate that certified reuse can reduce vision‑API calls while preserving output fidelity.

Don't Read the Log: Execution Traces Contaminate Verifiers in Video-Generation Agents

The paper investigates how providing execution traces to multimodal judges in agentic video‑generation systems can bias their verdicts. On a benchmark of 109 two‑event clips, traces that falsely report successful tool calls cause large‑language‑model judges to incorrectly accept 78–90 % of failures, while contradictory traces lead to 100 % rejection of correct clips. The effect persists even when judges are instructed to consider only the video frames, indicating that the vulnerability stems from the judges’ learned trust in tool logs rather than the visual content itself.
