🚀 What is Qwen3-8B?

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

• 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, code, mathematics, and Agent capabilities, rivaling larger previous generation models in performance and demonstrating extremely high practicality in real-world applications.

📚 Strong Training Foundation, Small Models Also Have Great Wisdom

Qwen3-8B was pre-trained on approximately 36 trillion tokens of high-quality multilingual data, covering web text, technical documents, codebases, and domain-specific synthetic data, ensuring broad knowledge coverage.

Its post-training phase incorporated a four-stage reinforcement process, specifically optimizing the following capabilities:

✅ Natural Language Understanding and Generation ✅ Mathematical Reasoning and Logical Analysis ✅ Multilingual Translation and Expression ✅ Tool Calling and Task Planning

Thanks to the comprehensive upgrade of its training system, Qwen3-8B's actual performance approaches or even surpasses Qwen2.5-14B, achieving a significant leap in parameter efficiency.

💡 Hybrid Inference Mode: Thinking or Quick Response?

Qwen3-8B supports flexible switching between "Thinking Mode" and "Non-Thinking Mode", allowing users to independently choose the response method based on task complexity.

Control mode via:

• API Parameter Setting: enable_thinking=True/False

• Prompt Command: Add /think or /no_think in the input

Mode	Applicable Scenarios	Examples
Thinking Mode	Complex reasoning, math problems, planning tasks	- Solving geometry problems - Writing complete project architecture
Non-Thinking Mode	Quick Q&A, translation, summarization	- Checking weather - Chinese-English translation

This design allows users to freely balance response speed and reasoning depth, enhancing the user experience.
