It turns model responses into expressive conversational speech across **100+ languages**, with **zero-shot voice cloning** and **inline control** over emotion, style, prosody, pauses, and sound effects. > [!TIP] > Released for research and non-commercial use under the **Boson Higgs Audio v3 Research and Non-Commercial License**. Production, hosted APIs, or revenue-generating use requires a separate commercial license. Prohibited: voice cloning without consent, impersonation, fraud, election deception, biometric surveillance, or any unlawful use.  Higgs autoregressive decoder consumes interleaved text and audio tokens. Audio is encoded by the **Higgs Tokenizer** into 8 codebooks at 25 fps, staggered via a **delay pattern**, then mapped to backbone hidden states through a **multi-codebook fused embedding**. Output codes pass through a **multi-codebook fused head**, are de-delayed, and decoded back to waveform. | Component | Spec | |---|---| | Backbone | ~4B autoregressive decoder (36 L, hidden=2560, GQA 32/8) | | Multi-codebook embedding / head | Fused...
