A Deep Dive into Agent Evaluation: From Basics to Advanced Practices

This article explains why evaluating AI agents requires more than answer correctness, outlines a four‑layer evaluation framework (result, process, efficiency, risk), compares short‑ and long‑horizon agents, and presents a practical methodology that combines objective and subjective metrics, rubric binary‑ization, case management, and infrastructure requirements for scalable, repeatable agent testing.

From Moonwalks to Cyber Cities: How WBench Maps the Limits of World Models

WBench, the first systematic multi‑turn benchmark for interactive video world models, evaluates 20 cutting‑edge models across navigation, actions, editing and view‑switching, revealing that no single model excels at all tasks, navigation is independent of visual quality, and multi‑turn interaction causes a 33‑point drop in performance.
