+For a limited time, and as available, you will see OpenHands-routed model IDs as marked as`Free`.
+
+The `Free` label applies only to those full `openhands/` routes. Endpoints from other providers with similar model names may have separate billing. The label remains visible after you select one of these models.
+
+When you create a local LLM profile, the form initially selects `openhands/glm-5.2` and derives the profile name `glm-5.2`. You can change either value before saving.

 For key details and available models, see [OpenHands LLM Provider](/openhands/usage/llms/openhands-llms).
 
 ### Local OpenAI-Compatible Endpoint
 
 A local server can be LM Studio, Ollama, vLLM, SGLang, or another service that exposes an OpenAI-compatible API. In the **Advanced** tab, enter the provider, exact model ID, endpoint base URL, and the required API key or a placeholder value when the server does not require one.
 
 The URL must be reachable from the **backend**, not only from your browser. For example, a backend in Docker cannot use `127.0.0.1` to reach a model server running on the host. Use the host address appropriate for that backend and confirm the endpoint's model inventory before saving.
