Kalos.art
What is Kalos.art?
lib.KALOS.art is a browsable style reference library for AI image generation. It catalogs artist names and art genres organized for Midjourney v5.2, Midjourney v4, SDXL, Stable Diffusion 2.1, and Stable Diffusion 1.5. Each model gets its own library slice so you can see which prompts and references work on the engine you actually run.
Most prompt libraries dump the same artist list for every model. lib.KALOS.art sizes each library to what that model recognizes, from 767 artists on SD 2.1 up to 1,340 on MJ v5.2 and SDXL, with 292 genre and medium categories alongside the artist index. Every artist and genre entry ships with 8 to 11 themed example galleries so you compare outcomes before copying a prompt.
AI art hobbyists and working prompt engineers use it to look up a style, copy a tuned prompt through the built-in copier, and save favorites once they log in. It sits beside the broader Kalos.art marketplace but stays focused on reference browsing rather than selling artwork.
Harmonai.org
What is Harmonai.org?
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.
