Who this book is for

In plain words: Qwen is Alibaba's family of free, open AI models for chat, code and images, which you can call online or run on your own computer.

  • Developers choosing an open model to build on
  • Anyone comparing Qwen with Llama, DeepSeek, GLM and Mistral
  • Not for: Not for you if you just want to use a chatbot. Try AI Made Crystal Clear.

Qwen is the open model family that quietly became a default: a dozen sizes and variants, most under Apache 2.0, strong enough to top a leaderboard on price-performance and small enough to run on your own GPU. The catch is the maze. Versions 3.5 through 3.8, crossed with Max, Plus, Flash, Next, Coder, VL and Omni, and three different licences in one generation. This guide decodes the lineup, gives you a VRAM sizing table that tells you which Qwen fits your card, prices the hosted API honestly against running it yourself, and answers the China question in three separate parts, because the app, the API and the weights on your own disk are three different stories.
