About this version
LLaMA 1 is a family of large language models released by Meta in early 2023 with parameter sizes ranging from 7 billion to 65 billion. Marketed as a research‑only release, the models were subsequently leaked and became foundational for many open‑source projects such as Alpaca and Vicuna, helping to seed the broader open‑source LLM ecosystem. The version is now retired and classified as legacy.
