Harmonai.org vs Sanalabs

Harmonai is a Stability AI lab that ships open-source generative audio models and notebooks for musicians. Its first public release, Dance Diffusion, lives in the sample-generator repo and covers unconditional sample generation, single-file style transfer, and interpolation between two clips. The org also maintains oobleck audio codecs and an audio-diffusion PyTorch fork on GitHub.

Unlike closed DAW plugins or hosted beat makers, Harmonai publishes training code and pretrained checkpoints you can run locally or in Colab. The Dance Diffusion notebook lists six public models, including maestro-150k at 16 kHz and glitch-440k at 48 kHz, plus datasets ranging from piano MAESTRO clips to field recordings from xeno-canto.

Producers, researchers, and hobbyists who want to experiment with diffusion audio rather than rent a black-box generator are the core audience. The site routes newcomers to a Discord community, and Stability AI's stable-audio-tools repo still documents the Dance Diffusion U-Net architecture Harmonai introduced.

Sana Labs builds enterprise AI tools for knowledge work and corporate learning under two products: Sana for AI agents across your company apps, and Sana Learn for training and onboarding. The Stockholm-based company now operates as part of Workday after its acquisition.

Where most enterprise AI vendors bolt a chatbot onto existing software, Sana connects to your company's documents, apps, and workflows so agents can find answers, generate reports, and automate multi-step processes. Sana Learn replaces a patchwork of LMS, LXP, and authoring tools with one platform that creates courses from PDFs and gives each learner a personal tutor.

The platform targets large organizations in financial services, law, manufacturing, and tech. Spotify, Polestar, and Foodora are among the customers cited on the site, with case studies reporting 10 hours saved per employee per week and course creation dropping from 3 weeks to 3 hours.
