# Qwen LLM

[Qwen](https://www.alibabacloud.com/en/solutions/generative-ai/qwen) provides powerful language models via the DashScope API. Use `ChatCompletionsLLM` from the OpenAI plugin with Qwen's OpenAI-compatible endpoint.

<Info>
  Vision Agents requires a [Stream](https://getstream.io/try-for-free/) account
  for real-time transport. Most providers offer free tiers to get started.
</Info>

<Tip>
  Qwen also provides [Realtime speech-to-speech](/integrations/realtime/qwen) with native audio I/O and built-in STT/TTS.
</Tip>
