Overview
Sophon-Realtime is an open-weights (Apache-2.0) full-duplex speech-to-speech model family that you host yourself on one 80 GB GPU with vLLM-Omni. It listens while it talks, handles barge-in and turn-taking server-side, hears tone (sarcasm, stress, laughter) and answers with an expressive voice. Its Live gateway speaks the OpenAI Realtime protocol (GA event names, function calling, barge-in truncation, PCM16 and G.711), so Pipecat’s built-inOpenAIRealtimeLLMService connects to it directly: point base_url
at your gateway. No extra package is needed.
Two builds share the same model: Tag (the most expressive voice) and
Flash (lowest latency, most sessions per GPU).
Installation
On the Pipecat side, install the OpenAI extra:Prerequisites
