Microsoft 365 is built on top of Microsoft’s current commitments to data security and privacy in the enterprise. Copilot is a sophisticated processing and orchestration engine that provides AI-powered productivity capabilities by coordinating: the power of large language models (LLMs) with your data in the Microsoft Graph, such as emails, chats, and documents that you have permission to access. The Microsoft 365 apps that you use everyday, such as Word, PowerPoint, and Teams, and the web. This integration provides real time intelligent assistance, enabling users to enhance their creativity, productivity, and skills. LLMs are a type of AI algorithm that uses deep learning techniques and vast data sets to understand, summarize, predict, and generate content. These LLMs include pre-trained models such as generative pre-trained transformers, GPT like GPT-4 Turbo, designed to excel in these tasks. LLMs process and generate natural language text by learning from large amounts of data from various sources such as books, articles, web pages, and images. An LLM takes an input, has several hidden layers that break down different aspects of language, and produces at the output layer. An LLM is a predictive engine that pulls patterns together based on preexisting text to produce more text. It doesn't understand language or math. So how does Copilot use LLMs? When you use Copilot for Microsoft 365, your query or prompt is processed through an approach called grounding, which improves the specificity of the prompt Copilot for Microsoft 365 accesses content and context through Microsoft Graph.
