What is Qwen?
Qwen is a family of large language models (LLMs) and large multimodal models (LMMs) developed by Alibaba Group that enables developers, enterprises, and researchers to perform natural language understanding, text generation, and various AI agent capabilities. It supports both powerful commercial versions via API and open-source versions for self-hosting and customization. Built on a transformer-based architecture, Qwen models are recognized for their robust multilingual support, particularly in Chinese and English, and their ability to integrate text, image, speech, and logical reasoning for diverse AI tasks. Recent iterations, such as Qwen3.5-Omni and Qwen3.6-Plus, have introduced omnimodal understanding, advanced agentic coding, and significantly expanded context windows, reaching up to 1 million tokens.
