Good example. And in fact you are calling the "engine" opensource, not the whole Quake game.
The 'assets" in most "opensource" AI models are not available.
Imagine if the Telegram client was open source but not the backend.
Imagine if Facebook open-sourced their front-end libraries like React but not the back-end.
Imagine if Twitter or Google didn’t publish its Algorithm for how they rank things to display to different people.
You don’t need to imagine. That’s exactly what’s happening! Would you call them open source because their front end is open source? Could you host your own back end on your choice of computers?
