Where it fits

Use GLM-5.2 when you want low-cost long-context coding and agent workflows with a 1M context window and unusually large 128K output ceiling.

When to skip it

Skip it if you need the deepest English-language provider ecosystem, or if your organization requires every benchmark number to come from a standardized provider table rather than product-positioning claims.
