L: Large Language Models (LLMs) – The Rise of Powerful Text Models

Large Language Models (LLMs) like GPT-3, LaMDA and Bard are deep learning models trained on massive amounts of text data. They can generate human-quality text, translate languages, write different kinds of creative content, and answer your questions in an informative way. LLMs are driving innovation in natural language processing.

M: Machine Learning (ML) – The Core of AI

Machine Learning (ML) is the ability of a computer system to learn from data without being explicitly programmed. ML algorithms identify patterns in data and use those patterns to make predictions or decisions. It’s a key component of many AI applications.
