A dated reminder
This is a September 29 catch-up notice. Mistral’s changelog lists October 31, 2026 for retiring its hosted zai-glm-5-2 alias and recommends zai-glm-5-3 instead. It gives no cutoff hour or timezone. [1]
The current GLM 5.2 page marks this Mistral-hosted, third-party model as deprecated and points to GLM 5.3 for new integrations. This is a host-specific notice; it does not establish retirement of Z.ai’s own services or downloaded weights. No API request was tested. [2]
Our take
Check the provider and model string in your configuration. Evaluate replacement behavior and cost against your requirements; a notice from one host does not require changing providers.
