Licensing

Licensing

The short version. The full map is LICENSING.md in the repository, and the third-party notices are in NOTICE.md. This page describes the project's intent and is not legal advice.

The rule

Everything the project made itself is under PolyForm Small Business 1.0.0: the engine, the app, the Linux packages, the scripts and the docs. Third-party code keeps its own license. One thing is different: the built PS5 title is distributed under GPL-3.0-or-later as a whole, because it links GPL-3.0 code from other projects (PS5_Vulkan and the PS5 payload SDK). The Linux edition links no GPL code and is PolyForm like everything else.

What that means for you

• Individuals and small businesses (fewer than 100 people and under about $1M a year in revenue): free. You may use, change and share it.
• Larger companies need a commercial license from the copyright holder for anything closed-source or outside PolyForm's limits.
• The PS5 title: whoever receives it also gets its source under GPL-3.0, and may use that under the GPL's terms, which means anything built from it and distributed must stay GPL with its source published. This is the dual-license model Qt and MySQL use: copyleft for everyone, PolyForm for small users, or a paid license.

What isn't licensed with it

• Model weights are not part of TokenStation5. Each is downloaded from Hugging Face under its own license; Gemma and Llama have terms of use of their own.
• Online services (Tavily, Hugging Face, Tailscale) are used with your own account or key, under their terms.
• The TokenStation5 name and icon are brand assets; neither license grants trademark rights.
• ps5-linux-tools (ps5_control), the ps5-linux kernel and ps5-linux-loader are other people's projects that you install yourself. TokenStation5 ships none of them; it calls ps5_control as a separate program if it is there.

Third-party code inside

The PS5 title and the Linux app include whisper.cpp and ggml (MIT), kokoro.cpp (MIT, with its GPL phonemizer removed), lwIP and wireguard-lwip (BSD-3-Clause), Project Nayuki's QR code generator (MIT), Mbed TLS (Apache-2.0), the Mozilla CA bundle (MPL-2.0), and glyphs from Inter (SIL OFL 1.1) and DejaVu Sans Mono. On the console the title also carries RADV/Mesa (MIT). ts5's quantization code follows ggml's reference implementation and its tokenizer defaults match llama.cpp's; ts5 is otherwise the project's own code and contains no llama.cpp. Every build carries NOTICE.md and the license texts.
