Qwen

Qwen is Alibaba Cloud's family of open-weight large language models, spanning some of the most capable and accessible AI models available in 2026. The Qwen lineup covers a remarkable range of use cases and hardware profiles:

**Qwen3 Flagship Models** — The Qwen3 series includes dense models from 0.5B to 32B and Mixture-of-Experts variants up to Qwen3-235B-A22B (235B total, 22B active). These models support hybrid reasoning (thinking/non-thinking modes), with standout performance in math, coding, and multilingual tasks across 100+ languages.

**Qwen3-Coder** — Alibaba's dedicated coding powerhouse: Qwen3-Coder-480B-A35B-Instruct is a 480B MoE model (35B active) purpose-built for agentic software engineering. It natively supports 256K context (expandable to 1M), can autonomously debug, write code, and browse documentation, and achieves top-tier scores on SWE-Bench and similar agentic coding benchmarks.

**Qwen3.5 Small Series** — Released in early 2026, this family targets on-device and edge deployments: 0.8B (smartphone), 2B (edge), 4B (multimodal agent), and 9B (compact production). Every model is natively multimodal — processing text, images, and video from a single set of weights — trained with advanced RL techniques that give even the smallest variants surprising reasoning depth.

**Qwen3-Omni** — A fully multimodal model (text, image, audio, video generation) released under Apache 2.0.

All Qwen models are open-weight and available on Hugging Face and ModelScope. The Apache 2.0 license makes them freely usable for commercial and research applications. Chat interface available at chat.qwen.ai.
