Qwen 3
Alibaba
Qwen 3 is the next-generation Qwen series LLM family offering multimodal, agentic, and high-reasoning capabilities across dense and MoE model variants.
Key features
- Thinking Mode: A configurable reasoning mode (enable_thinking) that lets the model engage chain-of-thought style internal reasoning to improve complex logical, mathematical, and coding responses while allowing switching to a non-thinking mode for efficient general-purpose dialogue.
- Mixture-of-Experts (MoE) & Dense Variants: A family of model sizes including large MoE configurations (e.g., extremely large-parameter MoE coder variants) and smaller dense checkpoints, enabling selection of performance vs. resource tradeoffs for inference and agentic tasks.
- Multimodal Vision-Language Capabilities: Qwen3-VL accepts image, text, and bounding-box inputs and produces unified text and localization outputs, with improved robustness to low-light, blur, tilt, and rare characters and stronger long-document visual-text understanding.
- Coder & Agentic Specializations: Qwen3-Coder variants (including very large MoE coder models) are optimized for coding, agentic browsing and tool use, and demonstrate state-of-the-art open-model performance on agentic coding and automated tool-use benchmarks.
