-## Advanced Usage
 
-Instead of using the `custom_llm_provider` arg to specify which provider you're using (e.g. together ai), you can just pass the provider name as part of the model name, and LiteLLM will parse it out. 
+## Rerank 
 
-Expected format: `<custom_llm_provider>/<model_name>`
+### Usage
