🚀 What is Qwen3-8B?

Qwen3-8B is part of the third-generation Qwen model series released by Alibaba in April 2025, an 8-billion-parameter dense model,adopting the Apache 2.0 open-source license,and can be freely used in commercial and research scenarios.

• Total parameters: 8 billion

• Architecture type: Dense (pure dense structure)

• Context length: 128K tokens

• Multilingual support: covers 119 languages and dialects

Despite its compact size, Qwen3-8B performs stably in reasoning, coding, mathematics, and agent capabilities, rivaling larger models of the previous generation and showing high practicality in real-world applications.

📚 Powerful training foundation: big wisdom in a small model

Qwen3-8B is based on approximately 36 trillion tokens of high-quality multilingual data,completing pretraining that covers web text, technical documents, code repositories, and synthetic data from professional domains, with broad knowledge coverage.

In the subsequent training stages, afour-stage reinforcement processwas introduced, specifically optimizing 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 actual performance approaches or even surpasses Qwen2.5-14B,achieving a significant leap in parameter efficiency.\

💡 Hybrid inference modes: think or respond fast?

Qwen3-8B supports flexible switching between “thinking mode” and “non-thinking mode,” allowing users to choose the response style based on task complexity.

Control the mode in the following ways:

• API parameter settings:enable_thinking=True/False

• Prompt instructions: add in the input /think or /no_think

Modes	Applicable scenarios	Examples
Thinking mode	Complex reasoning, math problems, planning tasks	- Solving geometry problems - Writing a complete project architecture
Non-thinking mode	Quick Q&A, translation, summarization	- Checking the weather - Chinese-English translation

This design lets usersfreely trade off between response speed and depth of reasoning,improving the user experience.
