GLM 5.3 (batch)
Open weightToolsZ.ai · Released August 2026
GLM-5.3 is a large-scale reasoning model from Z.ai, built for complex software engineering and long-horizon agent tasks.
It is part of Z.ai's GLM series, an open-weight line where the 5.x generation leads, Prime raises throughput, Flash and Turbo servings cut latency and cost, and 5V adds vision.
