Llama
Llama is a family of large language models from Meta whose weights can be downloaded, so developers can run and adapt them on their own hardware.
Also called Meta Llama
In more detail
Meta releases Llama models under its own licence, which allows broad use with some conditions. Because the weights are available, Llama became the base for thousands of community models and is popular for running AI locally.
It is often called open source, but it is more accurately an open-weight model. Meta also uses Llama in its own Meta AI assistant.
