At the Build 2025 conference, Microsoft announced the launch of new application programming interfaces (APIs) for the Edge browser, allowing web developers to integrate artificial intelligence directly into web applications via Edge. This was reported by The Verge.

These APIs provide access to the Phi-4-mini model, which operates locally on the device and has 3.8 billion parameters. This allows web applications to utilize AI for generating, editing, and summarizing text without relying on cloud services. Microsoft also plans to release APIs for text translation, further enhancing local AI capabilities.

The company positions these APIs as potential web standards compatible with other AI models and functioning across various platforms like macOS.

Developers can already test the new APIs in Edge Canary and Dev versions. This gives the Edge browser a competitive edge against Google Chrome, which also offers similar APIs supporting text generation, image creation, and translation.
