Chatterbox-Flash
The model weights and vendored runtime are derived from
ResembleAI/chatterbox-flash,
source commit 74e05baa8ce574bf2cc571702391a21f1b0d48c5.
Copyright (c) 2026 Resemble AI. Licensed under the MIT License. The complete
license text is reproduced in LICENSE and in
runtime/chatterbox-flash/LICENSE.
The derivative changes the FlashInfer engine/provider integration and adds a
canonical, source-free NVFP4 loader. The unchanged S3Gen, voice-encoder, and
tokenizer assets are not redistributed; the loader fetches them from the
immutable Chatterbox-Flash Hub revision recorded in nvfp4_config.json.
Chatterbox-TTS
Chatterbox-Flash uses architecture and runtime components from ResembleAI/chatterbox.
