Qwen

Qwen is a large language model family built by Alibaba Cloud.

The Qwen team aims at chasing artificial general intelligence and now focuses on building generalist models, including large language models and large multimodal models. We embrace open source, and previously we have released the Qwen model series, including the language models (Qwen), expert models (Qwen-Coder and Qwen-Math), and multimodal models (Qwen-VL and Qwen-Audio).

The latest model, Qwen2.5, features:

Dense, easy-to-use, decoder-only language models, available in 0.5B, 1.5B, 3B, 7B, 14B, 32B, and 72B sizes, and base and instruct variants.
Pretrained on our latest large-scale dataset, encompassing up to 18T tokens.
Significant improvements in instruction following, generating long texts (over 8K tokens), understanding structured data (e.g, tables), and generating structured outputs, especially JSON.
More resilient to the diversity of system prompts, enhancing role-play implementation and condition-setting for chatbots.
Context length support up to 128K tokens and can generate up to 8K tokens.
Multilingual support for over 29 languages, including Chinese, English, French, Spanish, Portuguese, German, Italian, Russian, Japanese, Korean, Vietnamese, Thai, Arabic, and more.
