Llama is Meta’s open-source family of large language models. Its range of model sizes and accessible licensing has made it a popular foundational model for AI development. section 2.5.2
Key characteristics include:
- Models are available in 8-billion- and 70-billion-parameter sizes. section 2.5.2
- Users must source their own datasets and infrastructure because Meta does not provide a public platform for training and running Llama variants. section 2.5.2
Access trade-off
Llama offers more direct access than proprietary model families, supporting experimentation and further training while shifting dataset and infrastructure responsibilities to the user. section 2.5.2
