Qwen (originally Tongyi Qianwen) is the advanced Large Language Model family developed by Chinese e-commerce and cloud giant Alibaba. Focused heavily on open-weights accessibility, Qwen has become one of the most popular alternatives to Meta's Llama family, leading open-source model leaderboards globally.
Qwen models (including the Qwen2.5 series) are trained on massive multilingual datasets, giving them superior translation and conversational capabilities in over 30 languages. Qwen's specialized coding models (Qwen2.5-Coder) and math models (Qwen2.5-Math) perform at parity with closed-source frontier models in competitive programming and advanced mathematics. Alibaba also provides visual and audio models under the Qwen-VL brand.
With an active developer ecosystem and official integrations with Hugging Face, Ollama, and vLLM, Qwen is widely used by companies worldwide to run private, secure LLMs on their own hardware.
