Sonnet 5.5's Terminal-Bench 4.0 Win: Costly Mirage? DevOps Model Selection Guide

The article analyzes Claude Sonnet 5.5's 70.6% Terminal-Bench 4.0 score, revealing it only surpasses Opus 5.5 at $13 per task via brute-force retries, while Opus dominates at practical $1-8 budgets; it maps scores to DevOps task complexity and provides a four-quadrant model selection matrix based on blast radius and state depth.

Why Max Reasoning Backfires: Opus 5.5 Medium Outperforms Max in Terminal-Bench 4.0

Terminal-Bench 4.0 reveals that excessive reasoning (max) reduces accuracy for top models like Opus 5.5 and GPT-6 Astra due to overthinking traps—agent drift, over-engineering, context dilution, and self-doubt—while high-end models at medium reasoning outperform mid-tier models at max reasoning at lower cost.

GEPA: Zero-Config Prompt Self-Evolution via Reflective Mutation & Pareto Optimization

This article details a production-ready GEPA (Genetic-Pareto Reflective Prompt Evolution) system that automates prompt optimization through a data-driven loop of inference, scoring, reflection, and Pareto-frontier selection, replacing manual trial-and-error with a task-agnostic, zero-configuration pipeline that supports classification, scoring, and clustering tasks while preserving explainability.
