Background & analysis
On November 11, 2026, a Reddit post on the LocalLLaMA community announced that Zyphra released an open-source text-to-speech model named ZONOS3-Mini. According to the summary posted that day, ZONOS3-Mini is Zyphra's compact, open-source text-to-speech model, built for natural reliable speech and high-fidelity voice cloning with just 100 million active parameters. It is designed to run in real time on phones and laptops, including directly in the browser, which makes on-device use possible without server calls. The summary lists two main capabilities: cloning a voice from an audio sample, or designing a character by shaping age, accent and vocal texture. It also says users can steer emotion, pace and delivery down to individual words. The stated use cases include games, narration and voice assistants, with the model meant to run locally. The post's excerpt cuts off partway through the description. As of this writing, that single announcement remains the only coverage on the topic.
