About the challenge
Z.ai just dropped GLM 5.1.
We’re inviting developers to push it to its limits.
This is a 1-week async build challenge focused on shipping real-world AI use cases using GLM 5.1: an agent-first model optimized for long-horizon reasoning, coding, and multi-step execution.
Build something real. Ship it publicly. Make it visible!
Top projects will earn cash prizes/coding plan, get featured by Z.ai, and gain global visibility across the developer ecosystem.
