Liu Zhiyuan calls for a practice-based AI evaluation system over leaderboard metrics

Tsinghua professor and ModelBest chief scientist Liu Zhiyuan published an opinion piece in Guangming Daily proposing a practice-based AI evaluation system. He argues AI competition is shifting from single models to whole systems, while leaderboard-driven evaluation reinforces a scale-and-compute development model; efficiency and cost should be built into evaluation to steer the industry toward efficiency- and value-oriented competition.

He outlines three levels: (1) evaluate concrete applications as complete systems—industry data, business rules, tools, human review—across procurement, validation, and operation, with controlled validation for high-risk domains; (2) assess industry-level outcomes via sector-run real-task libraries scoring both completion and unit cost; (3) measure overall contribution by incorporating AI's impact on productivity, employment, and public services into national statistics, with grassroots users' real-world benefit as a key yardstick.
