Qwen

Open-weights LLM family from Alibaba. One of the leading open-source model families as of early 2026, rated alongside DeepSeek as having surpassed Llama in capability.

Why It Matters

Qwen (pronounced “Qwen”) is notable for releasing strong multilingual models with permissive licensing. The Qwen family covers a wide range of model sizes — from small (0.5B) to very large — making it useful for deployment on a variety of hardware.

Notable Versions

Qwen releases are tracked numerically (Qwen2, Qwen2.5, Qwen3). Each generation generally improves on coding, reasoning, and multilingual capability.

Compared to Other Open-Source Models

One of the top-tier open-source options alongside DeepSeek. Both are stronger than Llama for most tasks as of early 2026. Available through Ollama, OpenRouter, and directly from Hugging Face in GGUF format.
