Llama (Large Language Model Meta AI, formerly stylized as LLaMA) is a family of large language models (LLMs) released by Meta AI starting in February 2023.[2] The latest version is Llama 4, released in April 2025.[3]
Llama models come in different sizes, ranging from 1 billion to 2 trillion parameters. Initially only a foundation model,[4] starting with Llama 2, Meta AI released instruction fine-tuned versions alongside foundation models.[5]
Model weights for the first version of Llama were only available to researchers on a case-by-case basis, under a non-commercial license.[6] Unauthorized copies of the first model were shared via BitTorrent.[7] Subsequent versions of Llama were made accessible outside academia and released under licenses that permitted some commercial use.[8]
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.[9]
