Suno began rolling out v6, a set of music generation models built with major music companies. Warner Music Group is among the partners involved in training and making them. Suno says the new models are faster and produce higher quality output. The arrangement pays record labels for the music used. Suno announced the rollout in a blog post on Wednesday. Bloomberg reported the launch the same day. Earlier Suno models were released without such label cooperation, and the company has faced industry objections over training data.
