Latest update (11-09 17:22): SGLang-Omni adds day-0 support for Zonos3-Mini voice-cloning TTS

Overview: Zyphra releases ZONOS3-Mini, an open-source text-to-speech model with voice cloning and word-level control, with open weights on Hugging Face and code on GitHub. Zyphra says the model runs on-device and in real time, including on a phone, because it activates only part of the model at each generation step and uses a new audio codec that cuts speech tokens from 774 to 150 per second.

The model is also available through Zyphra Inference and a browser playground. Zyphra offers 20 hours of free audio to people who comment "ZONOS" within 2 days of its announcement post.

SGLang says SGLang-Omni runs ZONOS3-Mini on day 0. SGLang describes the model as an 800M-parameter mixture-of-experts system that activates 80M parameters per token, and says first audio streams back in 57 ms on one H100.
