GLM-5.3 is Z.ai's open-weight flagship model (743B parameters, 1M-token context), an incremental upgrade over GLM-5.2 with stronger coding and much better token efficiency per task. Reasoning is always on with low, high, and max effort levels (max by default), and Z.ai positions it as a top open-weight model for complex software engineering and long-horizon agent tasks.
