TEX: Test-Time Scaling Testing Agents via Execution-based Cross-Validation

TEX is a new test‑time scaling framework that uses execution‑driven cross‑validation to generate and refine tests for language‑model agents. By running agents in parallel and cross‑executing each test against every patch, TEX builds a $K imes K$ feedback matrix that guides objective refinement without sharing verbose traces. On the SWT‑Bench Verified benchmark, TEX reaches 86.4% accuracy—setting a new state‑of‑the‑art and improving over single‑agent baselines by 9.0%—and even random selections from its outputs outperform the previous best score.

Agentic Routing: The Harness-Native Data Flywheel

arXiv:2607. 11399v1 Announce Type: cross Abstract: Large language model agents are increasingly executed not by a single model call, but by an execution harness that manages observation, context, control, action, state, and verification.

AgentHop: A Diagnostic Benchmark for Agentic Multi-Hop Question Answering over Scientific Citation Graphs

AgentHop is a diagnostic benchmark comprising 1,011 multiple‑choice questions that test agentic multi‑hop question answering over scientific citation graphs. It provides a controlled seven‑tool sandbox with fixed token, turn, and tool‑call limits, allowing researchers to dissect model performance across four operational axes: retrieval, synthesis, tool‑call, and resource management. Analysis of 19 models shows distinct family‑specific behaviors, such as GPT models committing early, Anthropic and GLM checkpoints verifying before committing, DeepSeek and Kimi over‑searching, and Gemini‑3 Pro maintaining balance, while within‑family differences are revealed in retrieval versus synthesis strategies.
