sophon-realtime

Sophon-Realtime v1: an open full-duplex voice model that hears your tone and speaks with one. This package installs the recommended Tag build as a vLLM-Omni plugin, plus a small command line to download and serve it on one 80 GB GPU.

pip install sophon-realtime          # Python 3.12, Linux, CUDA; installs vLLM 0.30 + vLLM-Omni 0.30
sophon-realtime serve                # downloads Sophon-Realtime-32B-Tag (~42 GB) on first run, then serves on port 8000
  • Full duplex: ws://HOST:8000/v1/realtime (turn-taking, barge-in, back-channels; OpenAI-Realtime-style)
  • POST /v1/chat/completions (audio in, text + audio out)
  • Options: --port, --gpu, --model DIR, --source modelscope|hf; sophon-realtime download only downloads.
  • Optional TensorRT for faster speech: pip install "sophon-realtime[trt]".

VoiceBench 82.8 and Big Bench Audio 81.8% (#1 among open full-duplex models), #1 in paralinguistic understanding, NVV-SuperBench 0.86 (zh) / 0.80 (en). Client examples, the Flash build, Live mode (OpenAI GPT-Live compatible) and fine-tuning: https://github.com/adventists-ai/sophon-realtime
