Qwen Realtime Audio Protocols
Separate Omni realtime sessions, realtime TTS and ordinary chat.
qwen3-omni-flash-realtime and qwen3.5-omni-flash-realtime use realtime sessions. qwen3-tts-instruct-flash-realtime uses realtime TTS. Ordinary qwen3-omni-flash-2025-12-01 uses Chat Completions.
Alibaba's native WebSocket path is /api-ws/v1/realtime?model={model}, with Bearer authentication. Omni and TTS use different event sequences.
ModelSell registers GET /v1/realtime, but the current Alibaba adapter does not translate the native realtime URL. Platform access requires a compatible, configured channel. A catalog openai label does not verify Alibaba native realtime support.
Do not copy ordinary chat examples into a realtime session.
