What Is Qwen 2.5?
Qwen 2.5 is Alibaba Cloud’s 2025‑generation large‑language‑model family that spans 1.5 B to 72 B parameters (and a 32 B reasoning‑optimized sibling) and now powers commercial, research and consumer products such as Qwen Chat, DashScope and an OpenAI‑compatible API gateway. Compared with Qwen 2, the 2.5 line introduces (i) a Mixture‑of‑Experts (MoE) core for efficiency, (ii) training on ~20 T tokens, (iii) stronger instruction‑following, coding and multilingual reasoning, (iv) vision‑language (VL) and fully multimodal “Omni” variants, and (v) deployment options ranging from Alibaba Cloud to self‑hosting via GitHub, Hugging Face, ModelScope and Docker/OLLAMA.
