Opera unveils WebAI standard to run AI models locally in the browser

The early preview lets developers tap on-device models like Google's Gemma without paying for cloud servers or per-request fees Opera wants your browser to do its own thinking. The company has introduced WebAI, a new web standard that lets AI models run directly inside the browser instead of pinging a distant data center. That matters because most AI features today are rented, not owned. Every prompt travels to someone else’s server, and somebody pays the meter. Opera is betting a lot of that work can happen on the machine already sitting on your desk. Opera released WebAI as an early preview on October 27, 2026. The first home for it is Opera One, the company’s flagship browser. Opera GX and Opera Neon are slated to get the feature later.
