Hey thanks for asking. I think that it is common for people to use AI for code help these days, so I think that banning AI code would limit who can participate in the jam.
I'll clarify the rules to say No AI except for AI generated code.
I'm not going to have an AI witch hunt or anything with the jam, unless it's something really obvious. This jam is a chance to have fun and practice game dev. I think that a lot of people can tell when something is AI generated or not, so even writing dialogue that is okay is better than relying on AI for it.
