About Llama2 by Meta
Llama 2, built by Meta, is a powerful open-source large language model that is absolutely free to use for both research and commercial purposes. This state-of-the-art model includes pretrained and fine-tuned language models ranging from 7B to 70B parameters.
The pretrained models in Llama 2 have been trained on a vast 2 trillion tokens dataset, providing double the context length compared to its predecessor Llama 1. Additionally, the fine-tuned models have undergone extensive training on over 1 million human annotations.
When it comes to performance benchmarks, Llama 2 outshines other open-source language models in various domains such as reasoning, coding proficiency, and knowledge tests. Its exceptional capabilities are fueled by leveraging publicly available online data sources for pretraining and publicly available instruction datasets along with the invaluable contribution of over 1 million human annotations for fine-tuning.
At Meta, we believe in an open and responsible approach to AI innovation. We have formed partnerships with cloud providers, companies, and researchers who share our vision. Our aim is to establish a collaborative AI innovation ecosystem that promotes responsible usage.
We provide various resources to support developers and researchers in utilizing Llama 2 effectively. This includes a comprehensive Responsible Use Guide, safety red-teaming to enhance performance and safety, an Open Innovation AI Research Community for academic researchers, and the Llama Impact Challenge which encourages the utilization of Llama 2 to tackle environmental and educational challenges.
As part of our commitment to community engagement, we maintain the Generative AI Community Forum in collaboration with the Stanford Deliberative Democracy Lab and the Behavioral Insights Team. This forum ensures that our community has a say in important decision-making processes regarding generative AI technologies.
