Google DeepMind Launches Lyria 3.5 in Google Flow Music with Major Advances

Google DeepMind has launched Lyria 3.5 inside Google Flow Music, delivering improvements across musicality, lyric generation, vocal synthesis, and creative control tools. This is a significant generative audio model update that pushes the quality ceiling for AI-generated music, particularly in areas like expressive vocals and structured lyrical output. For developers building audio-creative applications or exploring multimodal generation, Lyria 3.5 represents the current state of the art from one of the top labs in the space. The integration within Google Flow means the capability is accessible through a product interface, though API access for third-party developers will be a key factor in adoption. Creative-tool developers should monitor whether DeepMind opens programmatic access to Lyria 3.5 capabilities beyond the Flow product.
