Google announced at Google I/O 2025 that it is making the AI model that powers its experimental music production app, MusicFX DJ, available via an API.
The model, Lyria RealTime, is now in Google’s Gemini API and AI Studio platform. It can mix musical genres, change instruments, and alter the mood of AI-generated music, giving users control over the key, tempo, brightness, and other song characteristics and elements.
The launch of Lyria RealTime via API comes amidst an explosion of AI-powered music apps. There’s Udio and Suno, as well as the recently debuted Riffusion — among many others.
Many of these have proven to be controversial, particularly those driven by models trained on copyrighted music without permission. But Google pitches Lyria RealTime as a collaborative tool — one that can be used to interactively create, control, and even perform high-quality (48kHz stereo) songs.
Google didn’t announce pricing for Lyria RealTime ahead of its API rollout.
