<h1> Llama </h1>
<em>From Meta </em>
Welcome to the official Hugging Face organization for Llama models from Meta!

Requests will be processed within 1-2 days.
Llama 2 is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters.
Our fine-tuned LLMs, called Llama-2-Chat, are optimized for dialogue use cases. Llama 2 Chat models outperform open-source chat models on most benchmarks we tested, and in our human evaluations for helpfulness and safety, are on par with some popular closed-source models like ChatGPT and PaLM.
Read our <a href="https://ai.meta.com/research/publications/llama-2-open-foundation-and-fine-tuned-chat-models/">paper </a>, learn more <a href="https://ai.meta.com/llama/">about the model </a>, or get started with <a href="https://github.com/facebookresearch/llama">code on GitHub </a>.
