Llama 2 is a large-scale open-source language model developed by Meta. It is available for free for both academic and commercial use. This next-generation model includes pre-trained and fine-tuned language models, ranging from 7B to 70B parameters.
Llama 2 outperforms other open-source language models in various external benchmark tests, such as reasoning, programming, competency, and knowledge tests. The model leverages publicly available online data sources for pre-training and publicly available prompt sets, along with over 1 million human annotations.
Meta has established partnerships with cloud providers, companies, and researchers that support their open approach. They aim to create a responsible and collaborative AI innovation ecosystem. They offer resources such as a Responsible Use Guide for developers, security teams to enhance performance and safety, an Open Innovation AI Research Community for academic researchers, and the Llama Impact Challenge to encourage the use of Llama 2 in addressing environmental and educational challenges. Meta also maintains a Generative AI Community Forum, in consultation with the Stanford Deliberative Democracy Lab and the Behavioral Insight Team, to engage the community in decision-making around generative AI technologies.
