Seems to defeat the whole point of the jam, considering that it seems to be intended to showcase creator talent.
But I'd argue it also goes against the submission requirements. It says that you must submit an MP3 as well as your DAW, so how do you submit a screenshot of your work if there is no work to showcase? Furthermore, AI music is not "original", neither in the sense that you have created it, nor in the sense that you own the project files, nor that you created the audio that the AI is trained on.
I'm not the host, but I'd say that using AI is both against the rules and kind of offensive tbh.
