What is Harmonai?
Harmonai is a research lab backed by Stability AI that releases open-source generative audio models. Its stated goal is to make music production more accessible and to give artists more control over the tools they use.
According to the site, the lab's tools let users generate their own custom, effectively unlimited sound libraries, so they can produce new sounds without being restricted to existing sample packs. The homepage describes the project as AI built by musicians, for musicians, and invites people to join the community. The page itself does not list specific models, features or pricing.
