Llama 2: The second iteration of Meta’s open-source LLM. It’s not a single model but a collection of four models, each differing in the number of parameters they contain: 7B, 13B, 34B, and 70B parameters.
Llama 2 is a powerful language model that can be used for a wide range of natural language processing tasks, such as text classification, sentiment analysis, and machine translation. With its diverse set of models, Llama 2 can adapt to different contexts and tasks, making it a versatile tool for NLP practitioners.
