# Qwen3-8B

**The well-known MaaS service platform “SiliconFlow” is offering everyone free access to the Qwen3-8B model**. As a cost-effective member of the Tongyi Qianwen Qwen3 series, Qwen3-8B delivers powerful capabilities in a compact size, making it an ideal choice for intelligent applications and efficient development.

**🚀 What is Qwen3-8B?**

Qwen3-8B is **an 8-billion-parameter dense model**in Alibaba’s Tongyi Qianwen third-generation large model series, released in April 2025, **under the Apache 2.0 open-source license**, and can be freely used for both commercial and research scenarios.

* **Total parameters: 8 billion**
* **Architecture type: Dense (fully dense structure)**
* **Context length: 128K tokens**
* **Multilingual support: covers 119 languages and dialects**

Despite its compact size, Qwen3-8B performs steadily in reasoning, code, math, and agent capabilities, with performance comparable to the larger models of the previous generation, demonstrating extremely high practicality in real-world applications.

**📚 Strong training foundation, even small models can have great intelligence**

Qwen3-8B is based on **about 36 trillion tokens of high-quality multilingual data**for pre-training, covering web text, technical documents, code repositories, and synthetic data from specialized domains, with broad knowledge coverage.

Its subsequent training phase introduced**a four-stage reinforcement process**, which specifically optimized the following capabilities:

✅ Natural language understanding and generation\
✅ Mathematical reasoning and logical analysis\
✅ Multilingual translation and expression\
✅ Tool use and task planning

Thanks to the comprehensive upgrade of the training system,**Qwen3-8B’s real-world performance is close to or even surpasses Qwen2.5-14B**, achieving a significant leap in parameter efficiency.\\

**💡 Hybrid reasoning mode: think or respond quickly?**

Qwen3-8B supports **“thinking mode” and “non-thinking mode”** switching flexibly, allowing users to choose the response style according to task complexity.

Control the mode through the following methods:

* **API parameter settings**:`enable_thinking=True/False`
* **Prompt instructions**: add in the input `/think` or `/no_think`

| Mode                  | Use case                                         | Example                                                                         |
| --------------------- | ------------------------------------------------ | ------------------------------------------------------------------------------- |
| **Thinking mode**     | Complex reasoning, math problems, planning tasks | <p>- Solving geometry problems<br>- Writing a complete project architecture</p> |
| **Non-thinking mode** | Quick Q\&A, translation, summarization           | <p>- Check the weather<br>- Chinese-English translation</p>                     |

This design lets users**freely trade off between response speed and reasoning depth**, improving the user experience.
