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.

General 365: Meituan LongCat’s Open‑Source Benchmark Redefines LLM Reasoning Evaluation

The General 365 benchmark, built from 365 original seed questions and 1,095 variants across eight reasoning challenges, reveals that most mainstream large language models struggle with everyday logical tasks, achieving at most 62.8% accuracy and requiring far more tokens than on traditional subject‑specific tests.

Managing AI‑Generated Code with Agent‑Based Evaluation: Refactoring 310K Lines of Code

When over 90% of a codebase is produced by AI, system quality hinges on constraining AI rather than speed, and this article details how a team used an agent‑based evaluation framework, unified standards, and incremental refactoring to turn 310,000 lines of AI‑written code into a maintainable, low‑debt system.

LARYBench Introduces an ImageNet‑Style Benchmark for Embodied Action Representations Learned from Human Video

LARYBench (Latent Action Representation Yielding Benchmark) provides the first systematic, ImageNet‑scale evaluation for implicit action representations derived from large‑scale human video, decoupling representation quality from downstream control, and shows that general‑purpose vision models outperform specialized embodied models in both action generalization and control precision across diverse robot morphologies and environments.
