THIRD-PARTY MODEL WEIGHTS — NOTICE
===============================================================================
The license above (MIT with OpenAI/Anthropic Rider) covers ONLY the franken_tts
source code (the library crates, the ftts / franken_tts CLI, the
build/quantization tooling, and the documentation in this repository). It does
NOT cover any model weights.
franken_tts runs the Qwen3-TTS-12Hz-0.6B-Base model
(Hugging Face: Qwen/Qwen3-TTS-12Hz-0.6B-Base). The original model weights, and
any quantized derivative of those weights produced and/or distributed by this
project (for example a .fttsq artifact emitted by "ftts convert"), are licensed
under the Apache License, Version 2.0, Copyright 2026 Alibaba Cloud. Under that
license this project may legally redistribute derivatives of the weights
provided the Apache-2.0 license text and attribution travel with them. The full
Apache-2.0 text as shipped by the model's authors is embedded in the ftts
binary (printed by its license output) and preserved verbatim in this
repository's pinned truth pack.
When franken_tts distributes a converted weight artifact, that Apache-2.0
notice and attribution travel with it.
