Bypass logged in users | WordPress.org

We’ll keep it in mind as an official feature, but in the meantime, you could enable this behavior by adding a plugin like this:

<?php

add_action( 'init', function () {
  if ( is_user_logged_in() ) {
    remove_action( 'preprocess_comment', array( 'Akismet', 'auto_check_comment' ), 1 ); 
  }
}, 99 );

This worked on my site when I saved it as wp-content/mu-plugins/akismet-no-logged-in-check.php, but you’ll want to test and confirm that it works for you before deploying it.
