LLAMA

Llama is a family of autoregressive large language models released by Meta AI starting in February 2023, with the latest version being Llama 3.2, released in September 2024. The model weights for the first version were made available to the research community under a non-commercial license, but subsequent versions were released under licenses that permitted some commercial use. Llama models are trained at different parameter sizes, ranging between 1B and 405B, and were originally only available as a foundation model, but starting with Llama 2, Meta AI began releasing instruction fine-tuned versions alongside foundation models.learn more on wikipedia
