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.
Qwen TTS has a dedicated Realtime TTS guide, covering /api-ws/v1/realtime?model=... and the /v1/realtime?model=... alias. Omni conversations still require a compatible channel; TTS support does not establish native Omni realtime support. Consult the console for enabled models.
Do not copy ordinary chat examples into a realtime session.
