Like it or not, the AI music space keeps "moving forward," with more players jumping into the scrum every month or two. That means I've gotta roll out regular updates. So, here's version 4.0!
Update September 23, 2026:
Version 4.3 now uses stem splitting when we detect possible AI. This means each result takes a bit longer, but by analyzing vocals and instrumental separately, we can tell whether it's hybrid, pure AI, or something else.
Our core model still supports Suno, Udio, and Riffusion. Since our last update, six decent new models have emerged:
Each of these gave the old detector a run for its money. The new v4.0 SubmitHub model spots them easily.
Treblo has also provided an open-source model that we're using for secondary verification.
My methodology for this version was pretty much the same as v3: source a few hundred (or thousand) examples from each platform, then spin out different quality tiers (eg, 128kbps, 192kbps, WAV, mp4, flac).
From there, I run two analyses:
You can see a breakdown of both scores when running an analysis. Sometimes they disagree. When they both agree, it's a very strong signal.
One of the things that I did differently here is to set up a "hold out" group to test on - a set of songs that the training models never actually see. I know, it's a bit shocking this is the first time I've done this. A hold out group is fairly standard for this kind of testing, but somehow I managed. What I can tell you is that based on this results, this model is pretty rock solid.
So, can you trick the detector? Yep, you sure can. It's pretty much 100% accurate when looking at a song downloaded directly from one of the AI platforms. But as soon as you start fiddling with stems, production, and more, it gets a lot muddier.
Oh, um, not much. I've been working on an upgraded genre detector for 2 months now. Pulling my hair out, at this point, which isn't a good thing to do as a middle-aged man. This AI detector model is pretty buttoned up, so I don't anticipate any major changes until the next big AI music model comes along (Suno 6???).
Want API access? If you work for a label or distribution company, reach out via SH Labs. We're already powering the AI detection for a few cool platforms, including Traxsource, Bandcamp, GEMA, and a number of other distributors.
