Qwen vs. Llama 2

The Qwen LLM, developed by Alibaba Cloud's Damo Academy, is an innovative suite of large language models that utilize a vast array of text and code to generate text that closely mimics human language, assist in language translation, create diverse types of creative content, and deliver informative responses to a variety of questions. Notable features of the Qwen LLMs are: A diverse range of model sizes: The Qwen series includes models with parameter counts ranging from 1.8 billion to 72 billion, which allows for a variety of performance levels and applications to be addressed. Open source options: Some versions of Qwen are available as open source, which provides users the opportunity to access and modify the source code to suit their needs. Multilingual proficiency: Qwen models are capable of understanding and translating multiple languages, such as English, Chinese, and French. Wide-ranging functionalities: Beyond generating text and translating languages, Qwen models are adept at answering questions, summarizing information, and even generating programming code, making them versatile tools for many different scenarios. In summary, the Qwen LLM family is distinguished by its broad capabilities and adaptability, making it an invaluable resource for users with varying needs. As technology continues to advance, the potential applications for Qwen LLMs are likely to expand even further, enhancing their utility in numerous fields.

We are excited to unveil the latest version of our open-source large language model, which includes model weights and initial code for the pretrained and fine-tuned Llama language models, ranging from 7 billion to 70 billion parameters. The Llama 2 pretrained models have been crafted using a remarkable 2 trillion tokens and boast double the context length compared to the first iteration, Llama 1. Additionally, the fine-tuned models have been refined through the insights gained from over 1 million human annotations. Llama 2 showcases outstanding performance compared to various other open-source language models across a wide array of external benchmarks, particularly excelling in reasoning, coding abilities, proficiency, and knowledge assessments. For its training, Llama 2 leveraged publicly available online data sources, while the fine-tuned variant, Llama-2-chat, integrates publicly accessible instruction datasets alongside the extensive human annotations mentioned earlier. Our project is backed by a robust coalition of global stakeholders who are passionate about our open approach to AI, including companies that have offered valuable early feedback and are eager to collaborate with us on Llama 2. The enthusiasm surrounding Llama 2 not only highlights its advancements but also marks a significant transformation in the collaborative development and application of AI technologies. This collective effort underscores the potential for innovation that can emerge when the community comes together to share resources and insights.
