Llama 3

Overview

Llama 3 is Meta AI's open source LLM available for both research and commercial use cases (assuming you have less than 700 million monthly active users).


The successor to Llama 2, Llama 3 demonstrates state-of-the-art performance on benchmarks and is, according to Meta, the "best open source models of their class, period". Improvements to the pretraining -- 7X more data than Llama 2 --- and post-training -- careful curation of instruction-tuning data -- processes result in improved alignment and output quality
