GLM-5.2, the latest open-weights model from Zhipu AI, has claimed the top position on the Artificial Analysis Intelligence Index among all openly available models. This marks a notable shift in the open-weights leaderboard, which tracks quality, speed, and price across dozens of frontier and community models. The result signals continued momentum from Chinese AI labs producing competitive open-weights alternatives to proprietary frontier systems.
Vercel has expanded its AI Gateway by adding GLM 5.2, the latest release from Chinese AI lab Zhipu AI. The AI Gateway gives developers a single endpoint to route requests across multiple model providers with built-in caching, observability, and rate-limit controls. GLM 5.2's addition broadens the roster of non-Western frontier models available through the platform.
