Qwen LLM

Qwen provides powerful language models via the DashScope API. Use ChatCompletionsLLM from the OpenAI plugin with Qwen’s OpenAI-compatible endpoint.

Vision Agents uses Stream Video for real-time WebRTC transport by default. External WebRTC transports are supported as well. Most AI providers offer free tiers to get started.

Qwen also provides Realtime speech-to-speech with native audio I/O and built-in STT/TTS.
