Compare GLM 5.2 from Z.AI and GLM 5.3 Prime from Z.AI on key metrics including benchmarks, price, context length, and other model features. Access both models and hundreds of others through the AIHubMix API.
GLM 5.2GLM 5.3 PrimeGLM-5.2 is Z.ai’s flagship model for the era of long-horizon tasks. With a truly usable 1M-token context window, it can handle project-level engineering context, execute long-running tasks more reliably, follow engineering standards more consistently, and complete the full development workflow from requirements to multi-platform deployment in a single task.
GLM-5.3-Prime is the high-speed version of GLM-5.3, with comprehensive advancements in programming and agent capabilities that reach open-source SOTA levels. Its internal programming benchmarks are 50% better than the previous generation, and it can deliver end-to-end production-grade results. It exhibits emergent cybersecurity capabilities, with the CyberGym vulnerability-discovery benchmark achieving the current best. It supports a 1M-token context window, 128K-token output, and three tiers of deep reasoning, making it suitable for long-range, complex tasks.
