Gradium drops phonon-31m-en: a 64.5 MB local TTS that runs inside browser tabs
Gradium just released phonon-31m-en, a lightweight English text-to-speech model built on Pocket TTS and Kyutai's Mimi codec. Weighing just 64.5 MB in 8-bit quantization, it streams natural 24 kHz speech entirely on-device across laptops, smartphones, and web browsers under the Apache 2.0 license. Why it matters: offline, zero-latency voice agents just became dirt cheap to deploy anywhere.
