O QUE É

Llama is Meta’s large language model family, first released in February 2023 and distributed as open weights that can be downloaded and run in one’s own environment. From Llama 2 onward, Meta permitted commercial use and offered several sizes such as 7B, 13B and 70B; Llama 3.1 extended the largest version to 405B parameters. It is a pretrained base on which the community performs extensive instruction tuning and domain adaptation. Its open weights made it a default starting point for many open-source projects.

Por que vale a pena lembrar

By releasing large models as open weights under a commercially usable licence, it made “download a base model and fine-tune it yourself” common practice and opened the open-weight camp’s direct competition with the closed frontier.
