Choosing when a model thinks longer.
The Qwen team released and described Qwen3, a family of dense and mixture-of-experts language models with selectable thinking and non-thinking modes.
- AI’s role
- Qwen3 can use a slower step-by-step Thinking Mode or a faster Non-Thinking Mode; the team also reports support for 119 languages and dialects.
- Documented result
- Qwen announced models from 0.6B to 32B dense sizes and 30B-A3B/235B-A22B mixture-of-experts sizes, with pre- and post-trained variants available via Hugging Face, ModelScope, and Kaggle. Its source describes the two operating modes and reports multilingual support.
- Important limitation
- The source's model rankings and language-support claims do not establish comparable accuracy or cultural fit across every listed language or task.
