Blogger Leopeva64 announced his latest discovery on X on the 17th. In Edge Canary 138.0.3323.0 or later, several new feature logos related to “Phi mini” have appeared.
One of the functions called “Prompt API for Phi mini” allows the browser to call the built-in Phi-mini model to perform generative AI-related tasks.
Microsoft Edge browser was exposed to integrate the Phi-4 mini model to realize the end-side AI function.
Microsoft Edge browser was exposed to integrate the Phi-4 mini model to realize the end-side AI function.
Phi-4 is a small language model that requires low computing power and higher operating efficiency, especially suitable for reasoning classes or complex tasks. According to Microsoft, Phi-4 has about 14 billion parameters and excels in text generation.
According to the foreign media Windows Latest, compared with integrated ChatGPT, Phi-4 can significantly reduce costs. According to Microsoft’s description, Edge’s Prompt API will support the local execution of text summary, classification, rewriting and other tasks. However, the company also made it clear that the version at this stage does not have the ability to verify the facts.
At present, Edge has provided the “AI rewrite” function, which can complete similar functions but rely on cloud computing. The new API emphasizes the “end-side AI” capability, that is, the processing is completed directly through the local hardware of the device.
Microsoft has also added several interfaces to support the Phi-4-mini model, including:
Summarization API for Phi mini can use the built-in small language model (Phi-mini in Microsoft Edge) to summarize the text;
Writer API for Phi mini, this model can be used to create text;
Rewriter API for Phi mini, rewrite the text content.
In addition, there are two auxiliary function signs. One is to bypass the device performance threshold and directly enable the local AI model; the other is the log tool for debugging the operation of local AI functions.
According to IT Home, Microsoft is making the Edge browser the first AI-based browser on Windows 11. Last year, it was reported that Microsoft may be using a language model called Phi-3 to provide some AI functions for Edge, with The sample adopts the method of running locally on the device side.
