Open source
Last updated 13 November 2026
Zalmox is built on open-source software and openly licensed models; the About page lists them. When you install the Zalmox Runner, we distribute some of them to you inside its two images. This page gives you what their licenses entitle you to: the license texts and the exact source code. Each image also carries a notice at /licenses/NOTICE.md listing every component.

Written offer
For at least three years after we last distribute a Zalmox Runner image, anyone may ask us for the complete corresponding source code of any GPL- or LGPL-licensed part of it, including the Ubuntu packages. Write to support@zalmox.io (Theory Nexus LLC) naming the image and version (the tag, or the output of docker image inspect). We send it on a medium customarily used for software interchange for no more than the cost of physically performing the distribution, or as a download for free.
DINOv3
TRELLIS.2 uses Meta's DINOv3 image encoder. The Zalmox Runner downloads it from zalmox.io, under the DINOv3 License (Meta's copy), which you accept by using it; a copy is also saved next to the model on your machine. It forbids, among other things, uses related to military purposes, nuclear applications, espionage or guns and illegal weapons, and uses that break trade controls. Built with DINOv3.
Character animations
The animations a rigged character can be given come from Universal Animation Library 1 and 2 by Quaternius, released under CC0 1.0: free for any use, including in your games. Thank you, Quaternius.
Music and sound effects
Music is made with ACE-Step 1.5 (MIT). Sound effects and ambience are Powered by Stability AI: they are made with Stable Audio 3 Small-SFX under the Stability AI Community License. Its text encoder, T5Gemma, is under the Gemma Terms of Use. Music layers (drums, bass, melody) are split with Demucs (MIT). Audio is encoded with FFmpeg (LGPL/GPL, Ubuntu's build).
Everything else
The other components (PyTorch, TRELLIS.2, .NET, SkiaSharp and more) are under permissive licenses such as MIT, BSD and Apache-2.0; their texts are in the images next to each package, as /licenses/NOTICE.md describes. The models the runner downloads are listed with their licenses on the About page. Zalmox's own code is not open source and is covered by our terms.
