The GLM family from Z-AI has grown quickly, and we now offer five distinct GLM models across the Light, Balanced, and Power tiers. Here’s a one-stop reference for which one to pick.

The full GLM lineup on Chat-O

How to choose

Pick GLM-5 Turbo (Light) when speed and cost matter most

It’s the fastest GLM on the platform and the only one in the Light tier. Great for quick chat responses, autocomplete-style code generation, and high-volume agent loops where each step is cheap.

Pick GLM-4.7 (Balanced) as your balanced daily driver

Z-AI describes GLM-4.7 as its “latest flagship” for enhanced programming and more stable multi-step reasoning. If you don’t need the 1M context of GLM-5.2, GLM-4.7 is the sweet spot for everyday coding.

Pick GLM-5 / GLM-5.1 for traditional reasoning depth

GLM-5 and GLM-5.1 stay focused and predictable. GLM-5.1 specifically improves on long-horizon coding tasks compared to GLM-5.

Pick GLM-5.2 when you need the full 1M-token context

This is the heavyweight. Load a whole repository, run long agent workflows, and never lose the thread. Available in both Balanced and Power tiers.

One family, many tradeoffs

The whole point of a multi-model platform is that no single model is best for every task. With the full GLM lineup available, you can:

• Use GLM-5 Turbo for fast drafting
• Switch to GLM-4.7 or GLM-5 for balanced coding
• Jump to GLM-5.2 when a task needs the full context window

All five are live now in the model dropdown.
