Copilot is an artificial intelligence system developed by Microsoft that is based on large language model (LLM) technology. It uses deep learning techniques, including transformer-based neural networks, to analyze and generate human language and to provide context-aware assistance within software environments. Copilot is designed to integrate with Microsoft products such as Windows, Microsoft 365, GitHub, and other development and productivity tools, where it uses natural language input and application context to generate suggestions, responses, or actions.
The system can be used for a wide range of tasks including generating and editing text, summarizing documents, analyzing data, writing and explaining code, automating workflows, and assisting with problem-solving based on the user’s content and environment. On Copilot+ PCs, certain AI features can run locally using specialized on-device hardware such as neural processing units (NPUs), improving performance, responsiveness, and privacy. Copilot does not possess understanding or intent but operates by predicting and generating language based on patterns learned during training and on contextual signals provided by the host application.
