+        api_key (str): The access key for the hosted NIM endpoints
+
+    There are two ways to access NVIDIA NIMs -
+     0. Hosted: Preview APIs hosted at https://integrate.api.nvidia.com
+     1. Self-hosted: You can run NVIDIA NIMs on your own infrastructure
+
+    By default the configuration is set to use the hosted APIs. This requires
+    an API key which can be obtained from https://ngc.nvidia.com/.
+
+    By default the configuration will attempt to read the NVIDIA_API_KEY environment
+    variable to set the api_key. Please do not put your API key in code.
