An arms race is taking place between music-making AI models capable of generating high-quality songs from text prompts. Suno's v3 model and the newly launched start-up Udio are leading the competition. Udio's output is believed to have crisper sound quality compared to Suno's, with fewer traces of machine-generated origins. Udio quickly developed its product with the support of tech heavyweights and notable music names as investors. Both companies may have trained their AI models on copyrighted music, which has raised ethical and legal concerns.

Udio's pre-release beta version produced songs that closely resembled Tom Petty's voice, indicating the need for better filters to avoid copyright infringement. While Suno targets average consumers, Udio positions itself as a tool for musicians, offering creative abilities that alleviate concerns over training data. The founders believe their output is transformative and have plans to give artists financial control over their voice likenesses. Suno generates two-minute music clips, while Udio is more customizable but requires some familiarity to use. Musicians concerned about the platform are encouraged to reach out for more information.
