Qwen-Audio-3.1-Realtime-Plus: full-duplex voice model with think-act-speak loop
Alibaba Qwen's real-time duplex speech model (text+audio in/out) that reasons, uses tools, and decides when to speak mid-conversation, with function calling and web search.
Why it matters
One of the first Chinese open-API full-duplex voice models with explicit think/act/speak reasoning and GRPO-trained tool use; 262K context at $6.4/M audio-input tokens vs $32 for OpenAI's realtime model.
What you could build with it
A call-center SaaS team could prototype a bilingual voice agent that interrupts, backchannels, and calls tools mid-conversation - at roughly one-fifth the audio-token cost of Western realtime APIs.
Does it hold up?
Too early to judge - API docs live, no independent benchmarks or production deployments reported yet.
