Microsoft has unveiled the Windows Copilot Runtime, enhancing Windows 11 with over 40 AI models for developers to integrate into their apps. This new feature, part of the Copilot Plus PCs, includes a library of APIs for on-device model deployment, aiming to facilitate the creation of more AI-powered applications. The Copilot Runtime and its accompanying library, which offers APIs for features like Studio Effects and Live Captions, will be accessible to developers starting June, marking a significant step in Microsoft's strategy to dominate AI development on Windows.

Microsoft's recently launched Copilot Plus PCs introduce a suite of new AI features integrated directly into Windows 11, enhancing both functionality and user interaction34. These features are powered by more than 40 AI models running on Windows 11, thanks to the new Windows Copilot Runtime126. This runtime environment allows developers to utilize a library of APIs for building their own on-device AI models.
Key AI features include Studio Effects, Live Captions Translations, OCR, and Recall with User Activity. These tools are designed to improve user experience significantly. For instance, Recall enables the documentation and storage of user activities on the PC, creating a searchable timeline of past activities. This feature is supported by the Windows Semantic Index which stores data locally, ensuring privacy and quick access.
Additionally, developers can integrate these AI capabilities into their applications with minimal coding required, enhancing app functionality and user engagement. For example, Meta plans to incorporate Windows Studio Effects into WhatsApp, adding features like background blur and eye contact during video calls2. This integration signifies a broader application of Microsoft's AI tools across different platforms and apps, marking a significant advancement in PC technology driven by AI.

The Windows Copilot Runtime introduced by Microsoft serves as a foundational platform designed to enable the development and integration of AI-driven applications directly into the Windows operating system. This runtime system is equipped with a library of APIs, allowing developers to access ready-to-use AI functionalities such as Studio Effects, Live Captions Translations, OCR, and Recall with User Activity12. These tools are part of a broader strategy to make Windows an open platform for AI development, facilitating the creation of more personalized and efficient applications by utilizing the advanced capabilities of AI directly on devices15. This initiative not only enhances the functionality of Windows but also opens up new possibilities for developers to innovate with AI technologies in their applications, leveraging the local processing power of modern hardware to deliver enhanced privacy and performance13.
