# Opera Introduces WebAI: Browser Can Run AI Models Locally, Without Cloud or Subscriptions

## Key Points

- WebAI is a web standard for running AI models locally in the browser without the cloud
- The standard is architecture-agnostic and supports open models, including Google's Gemma and Apple's base model on Mac
- An early preview is available in Opera One, with features coming later to Opera GX and Opera Neon
- A per-site permission system similar to webcam access has been implemented
- Supports 64-bit Windows (Intel/AMD) and Mac with Apple chips
- Simultaneously introduced the experimental HTML-in-Canvas standard for embedding web pages into 2D/3D scenes

Opera has announced the development of WebAI, a new web standard that allows users to run and utilize artificial intelligence models directly within the user's browser without querying cloud servers. According to the developers, the standard is not tied to a specific architecture and works with various open-weight AI systems: at launch, users can access Google's lightweight Gemma model, and on Mac computers, Apple's built-in base model. Opera also notes that companies like Google and Microsoft support the standard, highlighting its character as an industry solution rather than a proprietary one.

### Local Models and Data Privacy

A key advantage of WebAI emphasized by Opera is privacy: data processed by the local model remains on the user's device, and the user retains full control over the AI on their computer. In the announcement, the company stresses that developers do not need to build their own infrastructure or pay for every request, and users do not need to buy subscriptions to AI services. The standard enables generating text, classifying content, and matching data directly inside the browser. The main trade-off remains the increased hardware load: final AI performance directly depends on the technical specifications of a particular computer.

### Security: Permissions Similar to a Webcam

For security purposes, Opera has implemented a per-site permission system similar to the webcam access mechanism. Every site must obtain explicit user approval before it can invoke the local model. Early preview features must be enabled manually — they are not turned on by default. According to the developers, this approach reduces the risks of unauthorized use of local computing resources and data.

### Where the Technology is Available and Supported Devices

The first WebAI features are already available in the flagship Opera One browser as an early preview version. Similar capabilities will soon appear in Opera GX, a browser for gamers and streamers, and in Opera Neon, which uses AI agents to perform tasks. At the current stage, the technology supports 64-bit Windows PCs (Intel/AMD) and Mac computers with Apple chips. Kristian Kolondra, Opera's Executive Vice President of Browsers and AI, presented the technology launch as part of the company's announcement.

### HTML-in-Canvas: Web Pages in Three-Dimensional Space

Simultaneously with WebAI, Opera introduced another experimental standard — HTML-in-Canvas. The technology allows developers to embed interactive web pages into 2D and 3D scenes, while all standard elements — buttons, menus, and forms — remain fully functional even when the page moves in a virtual three-dimensional space. As a demonstration, the company showed the Gamer Room project, a 3D room with fully functioning websites running on interactive displays inside it.

### What This Means for Developers and Users

The introduction of WebAI and HTML-in-Canvas points to Opera's course toward transforming the browser into a platform for local AI and immersive web content. For developers, this means the ability to add AI features without their own infrastructure and without paying for every request, while for users, it provides access to AI without subscriptions and with data kept on the device. At the same time, the practical utility of the technology will depend on the performance of the user's hardware, which may initially limit the early preview audience.
