Use Z.AI GLM models from your GLM Coding Plan in GitHub Copilot Chat.
Also from the same developer: Lodestar walks you through how code works, explains anything you hover, and reviews your changes on any model in VS Code, including this extension's. 3 free runs included, then $5 one-time.
In the Copilot Chat model picker, open Manage Models, pick Z.AI GLM and paste your API key from z.ai.
Pick a GLM model in the model picker.
Set reasoning effort and temperature right in the picker.
The model list comes live from the Coding Plan API, and context windows, image support and effort levels come from models.dev, so new GLM models show up without an update. Brand-new models appear right away with safe default limits until models.dev lists them. Copilot's context window indicator works as usual.
