# Third-party components

AIOS does not change the licence of anything it bundles. Ubuntu packages keep their copyright and licences in `/usr/share/doc`. Distributing a complete image means honouring those licences, including the source-availability obligations of GPL components.

- **Ubuntu, Linux, systemd, NGINX and the userland utilities**: versions recorded in the build info, copyright inside the packages.
- **llama.cpp**: MIT licence; the source is the commit pinned in `build/versions.env`, from <https://github.com/ggml-org/llama.cpp>.
- **Mesa Vulkan drivers and the Vulkan loader**: MIT and related permissive licences, from the Ubuntu archive.
- **NVIDIA driver user-space libraries and kernel modules** (580 server branch): from the Ubuntu archive, under the NVIDIA software licence for the proprietary components and MIT/GPL-2.0 for the open kernel modules. They are redistributed unmodified, as Ubuntu distributes them and as the NVIDIA Software License allows Linux distributions to do; the proprietary modules are linked against the kernel on the machine that uses them.
- **stable-diffusion.cpp**: MIT licence; the source is the commit pinned in `build/versions.env`, from <https://github.com/leejet/stable-diffusion.cpp>, together with the ggml fork it pins.
- **whisper.cpp**: MIT licence; the source is the commit pinned in `build/versions.env`, from <https://github.com/ggml-org/whisper.cpp>.
- **FFmpeg**, used to convert recordings and encode spoken audio: from the Ubuntu archive, under the licences recorded in its packages.
- **Open WebUI**: upstream licence of release 0.11.3, including its branding requirements. The original branding and interface are kept; AIOS applies colours only, through the stylesheet Open WebUI loads from `/static/custom.css`. The downstream `+aios.1` wheel changes dependency constraints only, with recorded provenance.
- **React, Vite, TypeScript and the frontend dependencies**: licences in their npm distributions, versions in the lockfile.
- **Fonts and artwork**: the AIOS logo and the images derived from it are part of this repository and covered by its licence.
- **Diffusion model licences differ from language models**: Stable Diffusion 1.5 is CreativeML OpenRAIL-M, SDXL Turbo is under Stability AI's non-commercial licence, FLUX.1 schnell is Apache-2.0. The catalogue shows each licence and asks you to accept it before the download.
- **One model is included**: `sentence-transformers/all-MiniLM-L6-v2` (Apache-2.0), which embeds the documents attached in the chat and answers `/v1/embeddings`. Every other model is downloaded by the administrator, who must read its licence; the catalogue shows each licence and asks for it to be accepted. The tiny test model comes from the public `ggml-org/models` repository; read its model card and licence before redistributing it.
- **Voice samples**: the six reference voices in `config/voices` were generated by Qwen3-TTS 1.7B (Apache-2.0) and are not recordings of any person. The voice models themselves are downloaded from the catalogue under their own licence.
- **Optional CUDA package** (`make cuda-package`): llama.cpp's CUDA backend with the NVIDIA CUDA runtime and cuBLAS libraries, redistributed under the NVIDIA CUDA Toolkit licence. It is built and distributed separately from the ISO, which contains no CUDA component.

The MIT licence of the AIOS code does not grant rights over documents or components owned by third parties.
