The first Qwen technical report appeared in 2023, and later releases include specialized branches and open-weight models. Model capabilities and licenses vary by release, so claims about a particular model should be checked against its model card and license.
Tongyi Qianwen (Qwen) is a language-model family developed by Alibaba Cloud’s Qwen team. The original Qwen technical report was published in 2023, and the official repository documents early model releases that year. Later releases expanded to language, code, math, vision-language, and audio tasks. Some Qwen releases use mixture-of-experts architectures; others are dense models. Open-weight availability and license terms are release-specific: for example, the Qwen3 technical report states that its models are publicly accessible under Apache 2.0, while earlier Qwen releases used different license agreements. Do not assume that every model, dataset, or related service shares the same terms.
Using a Qwen-Coder model for code-related tasks, subject to the model’s documented scope
Comparing Qwen language-model releases in reproducible research
Deploying a compatible open-weight Qwen release under its stated license
Using specialized vision, audio, or math variants where the chosen release documents those capabilities
The Qwen team continues releasing models across tasks and sizes, including open-weight versions. A durable way to compare releases is to check the cited report, model card, evaluation setup, and license for the exact checkpoint being used. Newer model names and capabilities should be treated as release-specific facts rather than permanent properties of the family.

Tongyi Lab es el grupo de investigación de IA dentro de Alibaba Cloud, y Qwen (Tongyi Qianwen) es su familia de modelos insignia.
The official Qwen3 report states that Qwen3 models are accessible under Apache 2.0, while the original Qwen repository documents separate license agreements for earlier model weights.
Qwen incluye modelos especializados como Qwen-Coder (código), Qwen-VL (visión-lenguaje), Qwen-Audio y Qwen-Math.
Mixture-of-experts models route tokens to selected expert networks, so only part of the expert capacity is active for a token.
Qwen es la abreviatura en inglés de Tongyi Qianwen, la familia modelo de Tongyi Lab.
