Discounted rates are shown where a promotion is active. On the LMArena coding leaderboard coding-glm-5-free scores 1496 and glm-5.2 scores 1506.
coding-glm-5-freeglm-5.2coding-glm-5-free is the open and free version of coding-glm-5. To ensure stable service performance, usage limits are in place: up to 5 requests per minute, 500 requests per day, and a daily token allowance of 1 million.
GLM-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.
Prices are per million tokens. Time to First Token and throughput are rolling averages measured on AIHubMix.
