## Overview

Dia is Nari Labs’ dialogue-speech family; this entry opens Dia2. Scripts distinguish speakers with [S1]/[S2] tags and can use per-speaker audio prefixes to condition English dialogue saved as WAV. Current documentation limits generation to two minutes. The model has a streaming design, but the separate TTS Server with real streaming remains planned rather than an available hosted API. Main code uses Apache 2.0; Mimi and other components retain their licenses.
