Rules say AI generated content. 

I understand this rule for assets: images, music, sound effects, etc.

Does it also apply to code being generated by AI?

I'm fairly certain code applies as well because it falls under the category of AI generated content, so I recommend not doing as it is most likely not allowed.

This was answered by the host in another thread. Their reply was: "The no AI-generated content is to prevent any AI-generated assets within the game including art, writing, sound, and code.". So yes, it absolutely applies to code generated by LLMs/AI.
