With artificial intelligence advancing at breakneck speed, particularly in large language models, traditional benchmarking methods struggle to keep pace. Recognizing this challenge, Sequoia China unveiled xbench on May 26 - a next-generation evaluation tool designed to revolutionize how we measure AI capabilities.

The development of xbench traces back to Sequoia China's intensified focus on Artificial General Intelligence (AGI) following ChatGPT's 2022 debut. As AI agents proliferate across industries, static testing frameworks have proven inadequate for assessing real-world performance. xbench tackles this through a dual-track system: comprehensive datasets measure theoretical limits while practical evaluations gauge operational effectiveness.

At its core lies the Evergreen Assessment Mechanism, where tests evolve alongside technological progress. This dynamic approach eliminates stale question banks that enabled "ranking games" - a persistent industry issue where models optimize for known benchmarks rather than genuine capability. By continuously refreshing evaluation criteria, xbench maintains assessment integrity.

Beyond foundational metrics, xbench incorporates specialized evaluations for vertical applications like recruitment and marketing. The tool scrutinizes emerging capabilities critical for AGI: deep search proficiency, information synthesis, and advanced reasoning. Particular attention goes to multimodal models generating commercial video content and GUI agent reliability in fluid environments.

"Traditional benchmarks became obsolete the moment they published," notes Dr. Liang Wei, Sequoia China's AI research lead. "xbench represents a living measurement system that grows with the technology it evaluates."

The launch comes as enterprises increasingly demand trustworthy AI evaluation standards. Early adopters report xbench provides unprecedented insight into how models perform in production environments versus controlled tests.
