Microsoft has unveiled Windows AI Foundry at Build 2025, a comprehensive platform designed to simplify local AI development on Windows.
Microsoft already supports local AI apps on Windows via Windows Copilot Runtime, which offers various AI features through Windows AI APIs and Windows machine learning (ML). The models behind Windows Copilot Runtime on Copilot+ PCs run locally and continuously in the background.
At Build 2025, Microsoft is introducing Windows AI Foundry, a unified platform for local AI development on Windows, by bringing together Windows Copilot Runtime and several new capabilities. Windows AI Foundry will offer ready-to-use AI APIs powered by built-in AI models, tools to customize Windows built-in models, the ability to bring open-source models from Azure AI Foundry, and an inference runtime enabling developers to bring their models.
