Qwen3

Qwen3 is Alibaba Cloud's flagship, open-source LLM series: a high-efficiency model leveraging a Mixture-of-Experts (MoE) architecture and an adaptive Hybrid Thinking Mode.

Qwen3 is a powerful, open-weighted LLM (Apache 2.0) from Alibaba Cloud, engineered for peak performance and efficiency. Its core design features a diverse model lineup, including dense models (0.6B to 32B) and efficient MoE variants like the Qwen3-235B (22B active parameters). The key innovation is the Hybrid Thinking Mode, which dynamically toggles between deep, step-by-step reasoning and fast, non-thinking responses. This model supports an extensive 119 languages and handles long-context tasks up to 128K tokens, making it a robust, versatile choice for advanced multilingual and agentic workflows.
