# Z.ai GLM-5.1 — deprecation status

> No — GLM-5.1 is not deprecated as of August 3, 2026. Z.ai has announced neither a deprecation nor a shutdown date for it.

The April 2026 refresh of GLM-5, and the model people were pushed to when third-party hosts started dropping GLM-5. On Z.ai's own platform both are still listed and priced, which is the difference worth knowing: a model can be deprecated on someone else's inference service while the source provider keeps serving it.
