Qwen2-Audio 7B
Qwen2-Audio 7B, announced by Alibaba in mid-2024, is an open-weights audio-language model built on the Qwen2 stack. It supports voice chat, audio analysis (speech plus music and environmental sounds), and speech-based instruction following — and came with weights and reference inference code on Hugging Face for local experimentation.

Frequently asked questions
What is Qwen2-Audio 7B?
Qwen2-Audio 7B is Alibaba's open-weights 7-billion-parameter audio-language model. It accepts speech, music, and environmental sounds and responds with text, supporting both voice chat and audio analysis.
Can Qwen2-Audio produce speech output?
No — Qwen2-Audio is input-only multimodal. It understands audio and produces text. Pair it with a TTS model if you need spoken replies.
Where can I run Qwen2-Audio?
Weights are on Hugging Face under 'Qwen/Qwen2-Audio-7B-Instruct'. Reference inference uses the Hugging Face Transformers library and runs on a single modern GPU.
