Microsoft has officially rolled out GPT-5 across its entire AI ecosystem, bringing the long-awaited OpenAI update to users of Microsoft 365, the standalone Microsoft Copilot app, GitHub Copilot, and Azure AI Foundry.

Microsoft 365 Copilot’s GPT-5 and Smart Mode upgrade brings enterprise AI that combines web intelligence with your organization’s data — delivering precise summaries, analyzing emails, docs, spreadsheets and meetings across through Microsoft Graph for context-aware insights that ChatGPT can’t easily access.

GitHub Copilot, newly upgraded with GPT-5, is reinventing what developers expect from AI-powered coding with smarter suggestions, agentic workflows, and rewindable chat sessions.
