How big is your code base? I’ve worked with really large auto generated codes and mypy never took more than a minute or two to run. On more normal sized code bases it’s just a few seconds. It’s also incremental so subsequent runs are faster. Compare that to a c++ project where it’s not unusual to have 10, 15, 30 min build times. Or even worse, the time to wait for discovering the problem runtime in prod. The type hints also help in IDE navigation, where there is zero time to wait, pycharm can go to definition or find references in under a second.
