Good question. I’m an admin on the discord server, which I’m bringing up because we have a rule on AI assets there: ‘if you use generative AI in visual or audio assets, you must disclose this when posting the assets.’
Now, the server isn’t the jam and the jam isn’t the server, but extrapolating from that I’d say yes, it’s allowed, but please disclose its use. This is, of course, a personal suggestion. I’m not speaking on behalf of James (the host of the jam), who, by the looks of it, hasn’t issued any official statements yet.
