- Opera introduced WebAI, a new web standard that lets sites run AI models directly on a user’s device instead of in the cloud.
- WebAI supports open-weight models such as Google’s Gemma and, on Macs, Apple’s on-device foundation model, according to Opera.
- The feature is live as an early preview in Opera One, with Opera GX and Opera Neon to follow, and users must opt in.
- Opera says WebAI lets sites add text generation, content classification and relationship analysis without running their own AI infrastructure or paying per request.
What Happened
Browser maker Opera introduced WebAI, a new web standard that lets developers run AI models directly inside the browser rather than routing requests through cloud servers, TechCrunch reported (Oct 27, 2026). The feature launched as an early preview in Opera’s flagship Opera One browser, with Opera GX and Opera Neon planned to follow.
Why It Matters
The move extends Opera’s earlier work on locally run models and arrives as browsers compete over AI features, including the agentic-browser contest among ChatGPT Atlas, Perplexity Comet and Google AI Mode and other on-device efforts like Liquid AI’s browser-based model. It also plays to growing privacy concerns about cloud AI assistants that store user data on company servers.
Technical Details
WebAI is model-agnostic, but Opera names Google’s open-weight Gemma model and, on Macs, Apple’s on-device foundation model as working examples. “Developers can add AI features without running AI infrastructure or paying for every request,” the company said in its announcement, adding that processing happens entirely on the user’s device.
Who’s Affected
Web developers gain a standard way to add AI features like text generation and content classification without hosting model infrastructure or absorbing per-request inference costs. Opera users get AI features without a subscription, though Opera notes that performance depends on the user’s own device hardware.
What’s Next
Opera plans to extend WebAI from Opera One to Opera GX and Opera Neon “soon,” according to the company, without giving a specific date. Running models locally continues to trade cloud costs for local compute demands, which Opera acknowledges can affect device performance.
