LLaMA, which stands for “Large Language Model Meta AI,” is a series of state-of-the-art open-source large language models developed by Meta. The first version, LLaMA 1, was released in 2023 and came in four variants with parameters ranging from 6.7 billion to 65.2 billion. These models are built upon the transformer architecture, which is foundational to many modern AI applications. LLaMA has gained recognition for its performance and versatility in various tasks, including text generation and language translation ¹.

Subsequent versions, such as LLaMA 2 and LLaMA 3, have been introduced, with LLaMA 2 offering improved performance and a wider range of applications. LLaMA 2 includes models with parameters from 7 billion to 70 billion and is designed for both research and commercial use. LLaMA 3 further enhances these capabilities, featuring instruction-tuned versions optimized for conversational tasks ²⁴⁵.

Overall, LLaMA models represent significant advancements in the field of AI, providing powerful tools for developers and researchers alike.
