 ### `user_default_llm`
 
-The default LLM to use for a new RAGFlow user. It is disabled by default. To enable this feature, uncomment the corresponding lines in **service_conf.yaml.template**.
+Assigning default models to newly registered users through `user_default_llm` is deprecated and no longer supported in the open-source version. Uncommenting this section in **service_conf.yaml.template** does not configure models for new users.
 
-- `factory`: The LLM supplier. Available options:
-  - `"OpenAI"`
-  - `"DeepSeek"`
-  - `"Moonshot"`
-  - `"Tongyi-Qianwen"`
-  - `"VolcEngine"`
-  - `"ZHIPU-AI"`
-- `api_key`: The API key for the specified LLM. You will need to apply for your model API key online.
-- `allowed_factories`: If this is set, the users will be allowed to add only the factories in this list.
-  - `"OpenAI"`
-  - `"DeepSeek"`
-  - `"Moonshot"`
+Each tenant must configure its own model provider instances and credentials. New users do not automatically inherit an administrator's configured instances or default model selections.
 
-:::tip NOTE
-If you do not set the default LLM here, configure the default LLM on the **Settings** page in the RAGFlow UI.
+Go to **User settings** **>** **Model providers** to configure provider instances, add models, and select default models. See [Configure Model API Key](../../guides/models/llm_api_key_setup.md) for instructions.
+
+The Enterprise Edition provides role-level default model settings.
+
+:::note Builtin embedding
+If you deploy TEI, keep the shipped `user_default_llm.default_models.embedding_model` connection settings in **service_conf.yaml.template**. They are used by the TEI `Builtin` embedding service and do not assign administrator-owned model instances to new tenants.
