What GLM-4.5 is good for

GLM-4.5 is the larger member of Z.ai's original agent-focused GLM-4.5 pair, with a mixture-of-experts design and more active capacity than GLM-4.5-Air. It offers switchable thinking and non-thinking responses, so a workflow can spend reasoning time on hard questions without requiring it for every short exchange. Its strengths are tool-driven software engineering, browser-assisted tasks, planning and front-end implementation; the text-only interface is not a vision model. Later GLM-4.6 and GLM-4.7 generations extend the context and refine coding, so this model is most useful when you want the established 4.5 behavior or are comparing versions. Borg includes it in the subscription: Borg Fusion can route a suitable task to it, or you can choose its lane directly for consistent experiments.

How Borg uses it

GLM-4.5 is available as a subscription catalog lane in Borg. The catalog does not publish which Fusion profiles route to this model, so no routing role is claimed here. You can pick it directly by setting the OpenAI-compatible gateway model field to a listed lane id. Check the current catalog for availability before building a workflow around a lane.
