Open source notices

AIOS Lite is built on other people's work. This page lists it, with versions and licences, because those licences require attribution and because you are entitled to know what is running on your machine.

Model weights

Model weights are the largest component and carry the licences that matter most. We ship only weights under permissive licences that allow commercial redistribution with attribution.

Model	Tag	Licence	Published by	Notes
Qwen3 4B	`qwen3:4b`	Apache 2.0	Alibaba Cloud	Bundled as the default model. Licence read with `ollama show qwen3:4b --license`.
Phi-4 mini	`phi4-mini`	MIT	Microsoft	Offered as an alternative on machines where it fits better.
SmolLM2 135M	`smollm2:135m`	Apache 2.0	Hugging Face	Fallback for low-memory machines.

Models we deliberately do not ship: Qwen2.5, whose Research Licence permits non-commercial use only; and Llama 3.2 and Gemma 3, which permit commercial use but attach conditions we have not cleared. They are excluded by a licence check in the code rather than by anyone remembering to avoid them.

A note on PyInstaller and the GPL

PyInstaller is licensed GPLv2, which would normally be a problem for a paid closed product. It is not, because PyInstaller grants an explicit Bootloader Exception: its COPYING.txt gives “unlimited permission to link or embed compiled bootloader and related files into combinations with other programs, and to distribute those combinations without any restriction”. We read that file in the build environment rather than taking it on trust, and we distribute no modified PyInstaller source.

Getting the licence texts

The full text of every licence listed here ships inside the product, in a licences folder next to the launcher. If you find a component we have failed to credit, tell us through the contact page and we will fix it. That is a bug on our side, not an argument.

Questions about this page

Which AI model does AIOS Lite actually use?

Qwen3 4B by default, which is published under the Apache 2.0 licence. Phi-4 mini (MIT) and SmolLM2 135M (Apache 2.0) are used on machines where they fit better. All three permit commercial redistribution with attribution.

Why do you not ship Llama or Gemma?

Both permit commercial use but attach conditions — a required notice and naming rules for Llama, and use restrictions that pass to downstream recipients for Gemma. We have not cleared those conditions, so a licence check in the code excludes them by default rather than relying on anyone remembering.

PyInstaller is GPLv2. How can you sell this?

PyInstaller grants a Bootloader Exception giving unlimited permission to embed its bootloader in combinations with other programs and distribute them without GPL restriction. We distribute no modified PyInstaller source.

Where are the full licence texts?

Inside the product, in a licences folder next to the launcher. This page is the index; the folder has the complete text of each one.
