Llama 3

Overview

Meta Llama 3 represents a significant advancement in open-source large language models, offering state-of-the-art performance with its initial 8B and 70B parameter versions, released in April 2024. These models were pre-trained on an extensive dataset of over 15 trillion tokens, approximately seven times larger than the dataset used for Llama 2, and feature a significantly expanded vocabulary. Llama 3 demonstrates improved capabilities in reasoning, code generation, instruction following, and overall helpfulness compared to its predecessors and many contemporary models.

A key value proposition of Llama 3 is its open nature, providing broad access to researchers, developers, and businesses to build, innovate, and scale AI applications responsibly. Meta has emphasized responsible development, including new trust and safety tools like Llama Guard 2 and Code Shield. The models are designed to be more steerable and less prone to refusal. With an 8K context length at launch and plans for a much larger 400B+ parameter model with multimodal capabilities, Llama 3 aims to push the boundaries of what''s possible with openly available AI, enhancing productivity and fostering innovation across diverse industries.
