On February 11th, Google pushed Chrome 146 to the desktop platform testing channel, initiating the next phase of browser functionality and developer feature testing. The highlight of this update is the promotion of WebNN (Web Neural Network API) to an origin trial, providing support for directly invoking local neural network inference acceleration hardware within the browser. WebNN is a set of web-oriented neural network programming interfaces designed to fully utilize inference acceleration resources on user devices, such as NPUs and GPUs, enhancing the efficiency of web applications and front-end frameworks in calling local hardware for inference computations, thereby optimizing the web machine learning experience. Meanwhile, the Chrome 146 beta also introduces the Sanitizer API to enhance web application security, along with updates related to WebGPU and support for scroll-triggered animation effects. Additionally, Chrome 146 introduces an early preview of WebMCP, allowing AI Agents to directly query and execute services without simulating user web browsing, further improving AI-web interaction efficiency.
