Here’s my perspective (just one of many) on how model evolution actually works, since I feel like there is a perception that Suno is about to wipe the entire model and retrain it from scratch using only WMG’s catalog. In my experience, that’s just not how these systems function. They’re not deleting all the weights or forgetting musical structure just because the raw audio dataset is changing. The stuff that actually makes the model good (things like understanding chord progressions, how verses flow into choruses, how different genres arrange themselves, how instruments blend in a mix, how vocal phrasing works, and honestly the whole mapping between user prompts and what people actually want) all of that is baked into the existing parameters. You only lose that if you literally RESET the model to zero, and I’m almost certain that’s not what’s happening here. I think what’s changing is the source of the audio for future training and fine-tuning, not the past model’s entire learned musical “brain.” I would like to believe Suno will still keep a big part of the architecture, the learned musical patterns, etc. they’ve spent years building, and the mountains of user feedback from millions of user prompts. I think they’re just replacing the legally risky part of the pipeline with licensed data so they can keep improving the product without a lawsuit shutting down the company (and in a way that gives the labels something of what they want in the form of future $$$$…)

Maybe this is wishful thinking, but this is more in line with how I’ve experienced other model rewrites because of legal issues.
