- Song & score — YuE2-3B (m-a-p)
- Open lyrics-to-song model: it writes the vocals, the arrangement and the
editable ABC score. Served locally through the community GGUF build with the audio.cpp runtime. Model weights are CC BY-NC 4.0, but since September 2026 the authors let individual
creators use the model and publish, sell and monetize the songs it makes (credit optional); companies
need a licence for the weights.
- Instrumentals — community AR LoRA
- Vocal-free tracks (game assets, background music) use an instrumental
adapter for YuE2 trained by the community. The base model always sings; the adapter teaches it not to.
The adapter's weights are marked non-commercial only, so commercial use of instrumental tracks is
unclear.
- Cover art — Qwen Image
- Square album artwork is diffusion-generated from each song's style and
lyrics.
- Canvas video — MiniMax H3
- The vertical 9:16 loops are image-to-video clips anchored on the cover art,
then seamlessly looped for endless playback.
- Songwriting ideas — local writer LLM
- Batch themes, titles and lyric drafts are rolled by a local language model
inside pinned style packs, so each song varies within its genre.
