Llama-2, the latest open-source language model from Meta AI, surpasses previous models in various benchmarks and is designed for complex reasoning tasks, making it ideal for both research and commercial purposes. Building on the success of Llama-1, Llama-2 includes significant enhancements to improve performance and safety, with its training based on a large corpus of publicly available data fine-tuned for human preference alignment. In particular, the Llama2-13B-chat and Llama2-7B-chat models, with 13 billion and 7 billion parameters respectively, are adept at generating coherent dialogue by learning from conversational text such as chat logs and social media posts. These models are available through the Clarifai Python API Client, which facilitates easy access and supports the ongoing development of open AI models by Meta.
