It’s not currently open source, not because I’m opposed to that, but because I haven’t considered licensing or any of that yet. Also, I just finished this and got burned by the process, frankly. I want to get back to my main projects which are entirely my own IP. I will probably be willing to release the source code at some point in the near future. ACE-Step is theoretically about to release a new version of their model, the source may change based on that if I decide to keep working on this.
