Our Review
Qwen, developed by Alibaba Cloud, has become one of the most successful open-source AI model families globally. The Qwen 2.5 series spans from tiny 0.5B models that run on phones to 72B monsters that rival GPT-4. What makes Qwen remarkable is its combination of open weights, strong performance, and Alibaba's commitment to the open-source community. The models support over 100 languages, include vision capabilities in the VL series, and have spawned thousands of fine-tuned derivatives. For developers seeking to self-host capable models, Qwen is consistently among the top recommendations.
