Returns defaults and limits used by machine learning.

==== Request

`GET _ml/info`

==== Description

This endpoint is designed to be used by a user interface that needs to fully

meaning that the defaults should be used.  This endpoint may be used to find out
what those defaults are.


==== Authorization

You must have `monitor_ml`, `monitor`, `manage_ml`, or `manage` cluster
privileges to use this API.  The `machine_learning_admin` and `machine_learning_user`
roles provide these privileges. For more information, see
{stack-ov}/security-privileges.html[Security Privileges] and
{stack-ov}/built-in-roles.html[Built-in Roles].
