Route First, See Later: Enabling Vision Agents to Reason Scientifically by Separating Routing Policy from Action Spaces

The paper introduces ZETA, an architecture that separates routing policy from action execution in scientific vision agents. By resolving scientific intent before invoking specialized visual tools, ZETA treats measurement as a deterministic operation grounded in explicit geometry, enabling independent evaluation of routing correctness and downstream execution. Experiments on a zero‑shot benchmark of 51 scientific‑intent queries demonstrate that explicit routing semantics can dramatically improve routing accuracy, especially for models like Qwen 3.8 where segmentation routing accuracy jumps from 6.2% to 75.0% and detection routing accuracy from 60.0% to 100%.

The Hard Part Comes After Search: Benchmarking Web Agents on Synthesizing, Organizing, and Displaying Knowledge

The paper introduces KNOWS, a benchmark for evaluating web agents that act as assistants by retrieving, synthesizing, and presenting information across complex, multi-step browser tasks. It outlines a task design rubric, evaluation protocol combining deterministic checks with LLM judgments, and reports that current agents achieve only modest success, with the best performing agent succeeding on less than 3% of tasks. The study highlights significant gaps in agents’ tool use, visual understanding, and long‑horizon reasoning.

RSure-Agent: Reliable Use of Tool Observations for Remote Sensing Agents

RSure-Agent is a framework designed to improve remote sensing agents by verifying tool observations before they influence downstream reasoning. It introduces a verifiable observation protocol that requires tools to provide process evidence, and builds a task‑tool reliability prior from offline feedback to assess each tool configuration’s past performance. In evaluations on EarthBench, ThinkGeo, TerraLogic, and CHOICE‑420, RSure-Agent cuts error propagation by 21.3–25.9 percentage points and boosts overall accuracy, while also reducing the number of tool calls.

Making Every Tool Call Count: Necessary Tool-Evidence Path Rewards for Agentic Vision-Language Models

The paper introduces the Necessary Tool‑Evidence Path (NTEP) annotation scheme and its associated reward mechanism (NTEP‑R) to better supervise vision‑language models that use external tools. By explicitly specifying which evidence is needed and penalizing redundant tool calls, the authors train an 8B‑parameter model that shows improved accuracy and tool‑use efficiency across seven image‑grounded benchmarks. The approach demonstrates that fine‑grained supervision of tool‑evidence paths is essential for robust agentic VLM performance.

OSWorld-Science: A Benchmark of Computer Use Agents for Learning and Using Scientific Software

OSWorld-Science is a benchmark and evaluation environment for computer-using agents that use visual language models (VLMs) to perform scientific software tasks. It includes 12 VLMs and 146 high-quality tasks across domains such as molecular drawing, pathology image analysis, statistical computing, and physical simulation, with artifact-based evaluation and a harness that logs interactions and supports model comparison. The benchmark was developed through expert proposals and iterative human–AI co‑design, and results show that current VLMs still struggle with key scientific questions, offering insights into factors like language, reasoning, and context length.

MatToolBench: Benchmarking Multimodal Agents in Real-World Materials Science Workflows

MatToolBench is a new benchmark that evaluates multimodal GUI agents on professional materials science software. It contains 204 tasks across 10 tools in three modalities—GUI operation, OriginPro scripting, and code-based database queries—executed inside a Windows 11 VM. The benchmark offers fine-grained, expert-decomposed scoring and a high-performing multimodal judge for aesthetic assessment, revealing that strong general benchmark performance does not transfer to scientific workflows.

VTOS: Learning to Orchestrate Vision Tools by Co-Searching Solutions and Observers

VTOS (Vision Tools Orchestration Search) is a framework that adaptively orchestrates vision foundation tools—such as open‑vocabulary detectors, segmentation models, and post‑processing operators—by jointly searching for executable solution programs and observer programs that diagnose failures and provide feedback. The observer programs feed observations into a shared VisionThoughts knowledge base, guiding subsequent searches. In two case studies—dense object counting on LVIS‑Count and zero‑shot plant‑disease segmentation on PlantSeg‑OOD—VTOS outperforms static tool pipelines and agentic visual‑programming baselines, especially in complex scenarios like dense, occluded scenes and out‑of‑distribution segmentation.

AgentHorizon: Evaluating Agentic Judges for Long-Horizon Computer-Use Tasks

AgentHorizon is a benchmark comprising 1,373 computer‑use tasks with instruction‑trajectory pairs collected from 166 hours of human‑recorded activity across three operating systems. The benchmark uses a paired design that swaps instructions to create negative tasks, testing judges’ ability to distinguish successful trajectories from those that completed a similar but incompatible request. Eleven judges were evaluated, with GPT‑5.5 achieving the highest balanced accuracy of 80.9% on the full trajectory subset, while tool‑use benefits some models but harms others, revealing large variability in judges’ performance.
