 ### Added
 
+- **Zhipu AI (GLM) Provider** -- Support for Zhipu AI's GLM models (glm-4.5, glm-4.7, etc.)
+  via their OpenAI-compatible API at `https://api.z.ai/api/paas/v4`. Uses `provider: zhipuai`
+  in config with `api_key` or `ZHIPUAI_API_KEY` env var.

   line-based replacements, insertions, and deletions across multiple files in a single
   tool call. Hunks are applied bottom-up to preserve line numbers. 10 tests.
