With the growing importance of digital security, the Tongyi team at Alibaba Cloud launched Qwen3Guard on September 28th, which is the first safety protection model designed specifically for the Qwen family. This new model is built upon the powerful Qwen3 architecture and has been specially fine-tuned to provide more accurate and reliable security assurance for artificial intelligence interactions.
The primary purpose of Qwen3Guard is to enhance the security of artificial intelligence. Whether it's user input prompts or AI-generated responses, this model can efficiently identify potential risks and output granular risk levels and classification tags. This feature helps developers create more responsible and trustworthy AI applications, ensuring the security of user information.
In multiple mainstream security evaluation benchmarks, Qwen3Guard has demonstrated excellent performance, continuously maintaining a leading industry position. It can comprehensively cover security detection tasks in English, Chinese, and other multilingual scenarios. This makes its deployment and application around the world possible, providing high-quality security services to users in different regions.
To meet the needs of different application scenarios, Qwen3Guard offers two professional versions: Qwen3Guard-Gen (the generative version) and Qwen3Guard-Stream (the streaming detection version). The former is mainly used for secure classification of complete user inputs and model outputs, suitable for security labeling and filtering of offline datasets. The latter, for the first time, realizes real-time, streaming security detection during the model generation process, significantly improving the safety response efficiency of online services.
Both versions support different parameter sizes, offering three options: 0.6B, 4B, and 8B, to balance performance and efficiency, suitable for various deployment environments from edge devices to cloud services. In addition, Qwen3Guard supports 119 languages and dialects, ensuring it can meet the needs of users around the world.
While continuously advancing technological innovation, Alibaba Cloud is also opening up new prospects for AI safety guard services. With the release of Qwen3Guard, the security of artificial intelligence is expected to reach higher standards, driving the development of the entire industry.
