Moshi Review 2026

Open-source real-time conversational AI by Kyutai — a full-duplex voice assistant that can listen and speak simultaneously with low latency.

Moshi is an open-source, real-time conversational AI developed by Kyutai, a French AI research lab. Moshi represents a significant advancement in voice AI: it's a full-duplex speech model that can listen and speak simultaneously, enabling natural back-and-forth conversation without the awkward turn-taking delays typical of current voice assistants.

The technical achievement is notable. Traditional voice AI follows a pipeline of speech-to-text, then language model processing, then text-to-speech — each step adding latency. Moshi uses a single end-to-end model that processes audio directly, reducing response latency to approximately 200 milliseconds. This near-instantaneous response creates conversations that feel genuinely natural, with the ability to interrupt, overlap, and react in real time just like human conversation.
