BLOOM is a open source LLM developed as part of the BigScience Workshop by Hugging Face in collaboration with other research organizations.
A model proposed during the BigScience Workshop as an open-source alternative to GPT-3, BLOOM has since been superseded by recent models based on Meta's LLaMA model.

Llama 2 is Meta AI's open source LLM available both research and commercial use case.
The successor to LLaMA (henceforce "Llama 1"), Llama 2 was trained on 40% more data, has double the context length, and was tuned on a large dataset of human preferences (over 1 million such annotations) to ensure helpfulness and safety. It outperforms other open source models on both natural language understanding datasets as well as in head-to-head face-offs.
