Currently available model
According to the current BLACK HOLE server configuration, BLACK HOLE provides only Qwen3-8B.
For other models or a more stable service, use BLACK HOLE IN or another provider.
Qwen3-8B
The well-known MaaS service platform "SiliconFlow" provides 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 from the third-generation large model series of Tongyi Qianwen, released by Alibaba in April 2025. It is licensed under the Apache 2.0 open-source license, allowing free use 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. Its performance rivals that of larger previous-generation models, demonstrating high practicality in real-world applications.

📚 Strong Training Foundation: Big Wisdom in a Small Model
Qwen3-8B was pre-trained on approximately 36 trillion tokens of high-quality multilingual data, covering web text, technical documentation, code repositories, and synthetic data from specialized domains, ensuring broad knowledge coverage.
Its post-training phase introduced 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 exceeds that of Qwen2.5-14B, achieving a significant leap in parameter efficiency.\

💡 Hybrid Reasoning Mode: Think or Respond Quickly?
Qwen3-8B supports flexible switching between "Thinking Mode" and "Non-Thinking Mode", allowing users to choose the response method based on task complexity.
Control the mode using the following methods:
- API Parameter Setting:
enable_thinking=True/False - Prompt Instructions: Add
/thinkor/no_thinkto the input
| Mode | Use Cases | Examples |
|---|---|---|
| Thinking Mode | Complex reasoning, math problems, planning tasks | - Solve geometry problems |
| Non-Thinking Mode | Quick Q&A, translation, summarization | - Check weather |
This design allows users to freely balance response speed and reasoning depth, enhancing the user experience.
⚙️ Native Agent Support, Empowering Intelligent Applications
Qwen3-8B features outstanding Agent capabilities and can be easily integrated into various automation systems:
🔹 Function Calling: Supports structured tool invocation
🔹 MCP Protocol Compatibility: Natively supports the Model Context Protocol for easy extension of external capabilities
🔹 Multi-Tool Collaboration: Can connect to plugins such as search, calculators, and code execution
It is recommended to use it in conjunction with the Qwen-Agent framework to quickly build intelligent assistants with memory, planning, and execution capabilities.
🌐 Extensive Language Support for Global Applications
Qwen3-8B supports 119 languages and dialects, including Chinese, English, Arabic, Spanish, Japanese, Korean, and Indonesian. It is suitable for international product development, cross-language customer service, and multilingual content generation.
It excels particularly in Chinese understanding, supporting Simplified Chinese, Traditional Chinese, and Cantonese expressions, making it suitable for markets in Hong Kong, Macau, Taiwan, and overseas Chinese communities.
🧠 Strong Practical Capabilities, Broad Scenario Coverage
Qwen3-8B performs excellently in multiple high-frequency application scenarios:
✅ Code Generation: Supports mainstream languages such as Python, JavaScript, and Java, generating runnable code based on requirements
✅ Mathematical Reasoning: Performs stably on benchmarks like GSM8K, suitable for educational applications
✅ Content Creation: Writes emails, reports, and copy with clear structure and natural language
✅ Intelligent Assistant: Can build lightweight AI assistants for personal knowledge base Q&A, schedule management, and information extraction
