 The decision of *when to act* is **learned inside the model** (from second-by-second time-aligned data + RL), not bolted on by an external turn-detector or polling loop. Vision is the first-class driver; speech (ASR/TTS) is treated as pluggable I/O.

+## vLLM Usage
+
+[vLLM-Omni](https://github.com/vllm-project/vllm-omni) provides **day-0 support** for JoyAI-VL-Interaction! The model is a standard Qwen3-VL VLM served by a plain `vllm serve`; vLLM-Omni adds the real-time interaction layer on top — the per-second **speak / silence / delegate** orchestration, 3-tier summary memory, and pluggable ASR / TTS / delegation. For installation and full setup, see the [vLLM-Omni recipe](https://github.com/vllm-project/vllm-omni/blob/main/recipes/JD/JoyAI-VL-Interaction.md).
+
+### Online Serving
+
+```bash
+# git clone https://github.com/vllm-project/vllm-omni.git
+
+# 1. Serve the model (plain `vllm serve`, NOT --omni — it is vanilla Qwen3-VL)
+vllm serve jdopensource/JoyAI-VL-Interaction-Preview \
+  --served-model-name JoyAI-VL-Interaction-Preview --port 8061 \
+  --max-model-len 131072 --enable-prefix-caching --limit-mm-per-prompt '{"image":256,"video":1}'
+
+# 2. Start the interaction orchestrator (OpenAI-compatible, :8070)
+python -m vllm_omni.experimental.fullduplex.joyvl.serving.server --port 8070 \
+  --main-backend-url http://127.0.0.1:8061/v1 --main-model JoyAI-VL-Interaction-Preview
+```
+
+For the full browser demo — live webcam / RTSP input, voice (ASR/TTS), and the per-tick decision stream — run JD's official WebUI (`services/webui`) in front of the orchestrator; see the [vLLM-Omni recipe](https://github.com/vllm-project/vllm-omni/blob/main/recipes/JD/JoyAI-VL-Interaction.md) for the steps.
