+    === "Other"
+        Seafile AI utilizes [LiteLLM](https://docs.litellm.ai/docs/) to interact with LLM services. For a complete list of supported LLM providers, please refer to [this documentation](https://docs.litellm.ai/docs/providers). Then fill the following fields in your `.env`:
+
+        ```
+        COMPOSE_FILE='...,seafile-ai.yml' # add seafile-ai.yml
+        ENABLE_SEAFILE_AI=true
+
+        # according to your situation
+        SEAFILE_AI_LLM_TYPE=...
+        SEAFILE_AI_LLM_URL=...
+        SEAFILE_AI_LLM_KEY=...
+        SEAFILE_AI_LLM_MODEL=...
+        ```
+
+        For example, if you are using a LLM service with ***OpenAI-compatible endpoints***, you should set `SEAFILE_AI_LLM_TYPE` to `other` or `openai`, and set other LLM configuration items accurately.
 
-        !!! note "About use custom model"
+
+    !!! note "About model selection"
 
-            Seafile AI supports the use of custom large models, but the following conditions must be met:
-            - OpenAI compatibility API
-            - The large model supports multi-modality (such as supporting images, etc.)
+        Seafile AI supports using large model providers from [LiteLLM](https://docs.litellm.ai/docs/providers) or large model services with OpenAI-compatible endpoints. Therefore, Seafile AI is compatible with most custom large model services except the default model (*gpt-4o-mini*), but in order to ensure the normal use of Seafile AI features, you need to select a **multimodal large model** (such as supporting image input and recognition)
