Recently, Meta, the parent company of Facebook, released its new large language model, Llama 2, which outperforms previous models like GPT-3.5 Turbo and Claude 2 in handling long texts and complex tasks. Llama 2 was introduced in July 2022 and offers pre-trained language models in three sizes: 7 billion, 13 billion, and 70 billion parameters. Meta has partnered with Dell to help enterprise customers deploy Llama 2 locally through validated design combinations, rather than solely through cloud services. The Llama 2 model is open-source and can be used for research and certain commercial purposes. Meta has also collaborated with Microsoft and Amazon to provide this model on their cloud platforms. The launch of Llama 2 indicates significant progress by Meta in the field of large language models, positioning it as a competitor to OpenAI.
