-The ``partition_pdf`` function segments a PDF document by calling the document image analysis API.
-The intent of the parameters ``url`` and ``token`` is to allow users to self host an inference API,
-if desired.
+The ``partition_pdf`` function segments a PDF document by using a document image analysis model.
+If you set ``url=None``, the document image analysis model will execute locally. If you set
+the URL, ``partition_pdf`` will make a call to a remote inference server.
+``partition_pdf`` also includes a ``token`` function that allows you to pass in an authentication
+token for a remote API call.
