Microsoft Build 2023 in May was dominated by AI: specifically, the expansion of Copilot from a developer tool to a company-wide product strategy. Every product announcement referenced AI. The consistency was striking.
Microsoft 365 Copilot approaching GA
Microsoft 365 Copilot, announced in March, showed at Build with more specific functionality: meeting summaries in Teams that identify action items and decision owners, email drafting in Outlook based on context from previous messages, document generation in Word from brief outlines, and data analysis in Excel that translates natural language queries into formulas. The product remained in limited preview, but the feature depth was further along than competitors at the same point.
Azure AI Studio
Microsoft announced Azure AI Studio: a unified interface for building AI applications in Azure. It brings together model selection, fine-tuning, prompt flow (a visual tool for chaining prompts and tools), evaluation against test datasets, and deployment to Azure endpoints. For enterprise teams that want to build on LLMs without managing multiple separate Azure services, AI Studio provides a single workflow.
Copilot in Windows
Windows Copilot was announced: a sidebar AI assistant in Windows 11 that can answer questions, run Actions (system-level operations like changing settings), and use plugins from the Microsoft Store. The vision is an AI assistant that understands the full operating system context, not just the current document. The practical implementation at launch was more limited, but the direction points toward OS-level AI assistance.
The developer platform coherence
What stood out at Build 2023 was the coherence of Microsoft's AI developer platform: Azure OpenAI for model access, Azure AI Studio for building applications, Semantic Kernel as the SDK for integrating AI into applications, GitHub Copilot for the development workflow, and Microsoft 365 Copilot for end-user productivity. Each layer reinforces the others. The developer who uses GitHub Copilot is already in the Microsoft AI ecosystem. The enterprise that deploys Microsoft 365 Copilot has a natural path to building custom copilots via Azure AI Studio.
