Qwen
Alibaba's open-source AI chatbot surpassing Llama with dual-mode architecture and multimodal capabilities
About Qwen
Qwen (Tongyi Qianwen) is a family of large language models developed by Alibaba Cloud, with many variants distributed as open-weight models under the Apache 2.0 license. The Qwen3 model family includes both dense models (0.6B to 32B parameters) and sparse models, with the flagship Qwen3-235B-A22B featuring 235B total parameters with 22B activated through MoE design. The model seamlessly switches between thinking mode for complex reasoning and non-thinking mode for efficient dialogue. Qwen3 achieves competitive results against top-tier models like DeepSeek-R1, o1, and Gemini-2.5-Pro. The Qwen2.5-Omni model accepts text, images, videos, and audio as input and generates both text and audio output, enabling real-time voice chatting. Qwen has become the dominant open-source AI architecture in 2026, with over 40% of fresh AI models on developer hubs deriving from Qwen.
