Stability AI launches Stable Audio 3.0 models
Stability AI has released Stable Audio 3.0, a family of four audio generation models that range from 459 million to 2.7 billion parameters. The medium (1.4B) and large (2.7B) models can produce composed music up to 6 minutes 20 seconds long while maintaining musical structure and melody — more than double the length of prior versions. Stability AI is publishing open weights for the small SFX, small, and medium models; the large model is available only via API and paid self-hosting, with companies over $1M in revenue required to obtain an enterprise license. The company says the new models were trained on fully licensed data and has hired Ethan Kaplan to lead its professional music product efforts. The release arrives amid broader industry activity in AI music generation and ongoing legal and licensing disputes involving other firms in the space.
The release advances generative-audio capabilities (longer, higher-quality compositions) and expands access via open weights, affecting creative tooling and potential commercial audio content; licensing and enterprise restrictions also shape commercial adoption and rights management.

ElevenLabs launches Music v2 with mid-track genre switching
ElevenLabs released Music v2, an updated AI music-generation model that can switch genres mid-track, handle complex vocals and compositions, and add non-musical sound effects. The model lets creators generate and edit songs by sections (intro, verse, chorus) and stitch those sections together, and it can recreate specific parts of a track from prompts without altering other parts. ElevenLabs says Music v2 performs more reliably across languages, lyrics, vocals and arrangements, is trained on licensed data, and is cleared for commercial use. The model is available via ElevenLabs’ ElevenCreative tool and ElevenMusic platform, with ElevenAPI access coming soon.
