Llama (acronym for Large Language Model Meta AI, and formerly stylized as LLaMA) is a family of autoregressive large language models (LLMs) released by Meta AI starting in February 2023.[2][3] The latest version is Llama 3, released in April 2024.[4]

Model weights for the first version of Llama were made available to the research community under a non-commercial license, and access was granted on a case-by-case basis.[5][3] Unauthorized copies of the model were shared via BitTorrent. In response, Meta AI issued DMCA takedown requests against repositories sharing the link on GitHub.[6][7] Subsequent versions of Llama were made accessible outside academia and released under licenses that permitted some commercial use.[8][9] Llama models are trained at different parameter sizes, typically ranging between 7B and 70B.[4] Originally, Llama was only available as a foundation model.[10] Starting with Llama 2, Meta AI started releasing instruction fine-tuned versions alongside foundation models.[9]

Alongside the release of Llama 3, Meta added virtual assistant features to Facebook and WhatsApp in select regions, and a standalone website. Both services use a Llama 3 model.[11]
