Frequently asked questions

What is Qwen 3?

Qwen 3 is Alibaba Cloud's 2025 open-weights LLM family, covering dense 0.6B–32B sizes and MoE variants up to Qwen3-235B-A22B. All models ship under Apache 2.0.

What makes Qwen 3 special?

Three things: full Apache 2.0 license across the family, best-in-class Chinese and multilingual coverage, and a hybrid thinking/non-thinking mode that lets a single model switch between fast direct answers and long reasoning traces.

Is Qwen 3 safe for enterprise use?

The license permits it, but some Western enterprises avoid Chinese-origin models for data-sovereignty and supply-chain reasons. Evaluate based on your risk tolerance — the weights themselves are public and auditable.
