Malic and I are in two minds about this, he doesn't mind as much, wheras I would really prefer not to have AI-generated code used at all. However, it's not necessarily something we can really police or prevent.
I think if there's no chance of you being able to participate without it, you should use the time to try and learn from it at least. I will split the difference with Malic and say that, alright, you can use AI code assistance if you try to learn and understand what it's giving you so that later on, you don't need to rely on it and that you should try to use it as little as possible. What I don't want submitted are games that the developer doesn't understand the workings of.
This kind of stance is really only possible with code, as AI images and text are too detached from human creative reality to be learnable from, where code is deterministic. It might seem like a double-standard -- well, because it kind of is a double-standard -- but this is probably the only real way we can rule on this as co-hosts. I would really rather it not be used at all, but again, it's not something I can control or is even visible unlike art and text.
You can use AI to help you code, as long as you take the time to learn from what it gives you. Please do not submit games where you have no idea how it works. Images, text and audio must still not be AI-generated.
