# zai-org/glm-5.1

Calls to the model zai-org/glm-5.1 on DeepInfra stopped working on October 1, 2026.

DeepInfra retired the model zai-org/glm-5.1 on October 1, 2026. Calls specifying this model fail since that date. Any application still targeting this identifier receives an error instead of a response.

## What to use instead

Move to zai-org/GLM-5.3, which is recommended by DeepInfra.
