> **Key:** **The one-liner:** Qwen is how Alibaba quietly became the world's open-AI default — by giving most of it away.

**What it is.** **Qwen** is Alibaba's family of AI models, most released as open-weight under the permissive **Apache 2.0** licence — free to download, run, fine-tune and use commercially. That openness made it the most-downloaded open AI family in the world (reportedly over half of all open-source downloads).

**Why it matters.** Qwen is a major reason open-weight AI became competitive with closed frontier models — and the base that countless other projects build on.

> **Note:** **The 2026 twist.** Alibaba kept its most powerful model, **Qwen3.6-Max**, closed and API-only — openness to win the ecosystem, a paywall on the frontier.

## Key takeaways
