At the Build 2025 conference, Microsoft unveiled new application programming interfaces (APIs) for the Edge browser, enabling web developers to integrate artificial intelligence directly into web applications through Edge. The Verge reports on this.

These APIs provide access to the Phi-4-mini model, which operates locally on devices and contains 3.8 billion parameters. This allows web applications to leverage AI for generating, editing, and summarizing text without the need for cloud services. Microsoft also plans to release an API for text translation, enhancing the capabilities of local AI.

The company positions these APIs as potential web standards that will be compatible with other AI models and functional across various platforms, including macOS.

Developers can already test the new APIs in the Edge Canary and Dev versions, which boosts Edge's competitiveness against Google Chrome, which also offers similar APIs supporting text generation, images, and translation.
