Llama 2
The next generation of Meta's open source large language model. #opensource
What is Llama 2?
Llama 2 is Meta's open-source large language model representing a significant advancement in publicly available AI technology. Built on Meta's research in large language models, Llama 2 is designed to be accessible to researchers, developers, and organizations who want to build with advanced language models without proprietary restrictions. The model emphasizes performance, efficiency, and responsible AI development, making it suitable for many natural language processing tasks. By releasing Llama as open source, Meta enables the broader AI community to innovate, audit, and improve upon the model, democratizing access to powerful language AI capabilities that were previously limited to well-resourced companies.
