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.
