Kokoro — interactive visual explainer | Rudrite Research

Kokoro, an 82M non-autoregressive StyleTTS2 + ISTFTNet model, converts phonemes and a split style vector into 24 kHz audio in a single feed-forward pass without LLMs, diffusion, codecs, or tokens. Published by hexgrad in 2025, the model is now accompanied by a free interactive visual explainer that computes exhibits from real formulas and includes verbatim source quotes.
