Llama 3 AI

Llama 3 is Meta's latest addition to its Llama (Large Language Model Meta AI) series, which has been a key player in the open-source AI community. Llama 3 was launched on April 18, 2024, with two model sizes: 8 billion (8B) and 70 billion (70B) parameters. These models were trained on a massive dataset of approximately 15 trillion tokens, sourced from publicly available data.

Later, Meta introduced Llama 3.1 on July 23, 2024, expanding its capabilities with three primary model sizes—8B, 70B, and 405B parameters. This update improved efficiency, reasoning, and overall response quality.

Architecture and Technical Specifications
