The technology is designed to work with models from different providers rather than requiring developers to use a particular AI system. Initial support includes Google's Gemma family and Apple's on-device foundation model on compatible Mac computers.
Opera describes WebAI as part of a proposed standard supported by companies including Google and Microsoft. The approach is intended to give developers a consistent way to access local AI capabilities through the browser, although the current preview is limited to Opera's own software.
Privacy is another focus of the release. Because AI processing takes place on the user's computer, information submitted to a local model does not need to be transmitted to a remote AI provider. However, this does not automatically determine how individual websites or extensions collect, store or otherwise handle user data.
Opera has also introduced permission controls governing access to these capabilities. WebAI is turned off initially, and the browser does not download AI models unless the user chooses to activate the feature. Users can then manage which websites are permitted to interact with the available models.
The company has outlined several possible applications for developers, particularly those building browser extensions. Examples include tools that automatically arrange open tabs, identify misleading headlines and surface relevant employment opportunities.
These are potential uses of the technology rather than features being added directly to Opera's browsers.
To illustrate how WebAI can be implemented, Opera is providing sample extensions. One demonstration analyzes an article, identifies sentences with related meanings and converts the resulting groups into an animated visual presentation.
The release builds on Opera's earlier experiments with local AI processing. In April 2024, the company began offering access to on-device large language models through an experimental developer version of its browser. WebAI extends that work by providing a more structured interface that websites and extensions can use.
The preview currently supports computers running 64-bit Windows and Macs equipped with Apple silicon. Performance varies according to the processing capabilities of each device, making the available hardware an important factor in how quickly local models can complete tasks.
Opera plans to support additional open models and provide more tools for developers, although it has not announced when those additions will become available.
Alongside WebAI, Opera has announced a separate technology called HTML-in-Canvas, which enables developers to place functional web interfaces inside two-dimensional and three-dimensional environments.
The feature allows familiar HTML and CSS elements, such as navigation menus, buttons and forms, to remain interactive when incorporated into moving scenes. Developers can therefore combine conventional website controls with visual environments that would otherwise require different approaches to interface design.
Opera sees potential applications in games and other interactive content, including experiences developed for its gaming-focused Opera GX browser.
The two announcements address different aspects of browser development. WebAI provides a way to perform AI processing on local hardware, while HTML-in-Canvas gives developers more flexibility in how interactive web content is displayed.
For WebAI, adoption will initially depend on developers building features for the supported Opera browsers and users choosing to enable local AI access. Although Google and Microsoft are identified as supporters of the proposed standard, Opera has not announced broader browser availability.
The early preview gives developers an opportunity to test AI applications that operate without recurring cloud inference charges, while allowing users to retain greater control over where model processing takes place. Its longer-term reach will depend on additional browser support, compatible models and the applications developers create using the technology.
