Udio: Text to music from a bunch of former DeepMinders

With Suno 3 (and possibly Stable Audio 2), we are definitely experiencing a moment for music that parallels what we saw with ChatGPT 3.5 and Dall-E 2. The unexpected jump in quality (like sora recently) is again surprising (to me).

As with these 3 past breakthroughs, Google seems to be (slightly) lagging and again misses the "defining moment". I'm willing to say that OpenAI could have achieved something similar (and claim a 4th turning point), but the headache of copyright issues likely pushed them to focus on Sora first. I'm almost certain Udio and Suno were trained on (a lot) of copyrighted music.

recent text to music generation apps are amazing!
