The feature is available as an early preview in Opera One, with plans to bring it to Opera GX and Opera Neon. WebAI is intended to work with different AI models, including open-weight systems. Opera has named Google’s Gemma as one example, and the company says Macs can also use Apple’s on-device foundation model. The standard is not tied to one model or provider, however. Opera says it is built to support a broad selection of open-weight AI systems. ## What Is Opera WebAI? WebAI is Opera’s approach to running AI features locally in the browser. Instead of sending requests to a company’s cloud infrastructure, the AI processing can take place on the user’s own device. The standard follows Opera’s earlier work to bring locally run language models into its browsers. With WebAI, the company is expanding that direction into a browser-based standard that developers can use for AI features. Opera says WebAI can be used to: - Generate text - Classify content - Understand relationships between pieces of information These functions are handled in the browser rather than through a remote AI service. ## WebAI Availability in Opera Browsers Opera is initially offering WebAI as an early preview in Opera One, the company’s main browser. Users must opt in to use the feature. Opera says the same local AI capabilities are expected to come to two other browsers: - **Opera GX**, which is built for gamers and streamers - **Opera Neon**, which uses AI agents to perform tasks The company has not positioned WebAI as a feature limited to one browser or one AI model. Its stated aim is broader support for locally deployed, open-weight models. ## How Local AI Processing Works in the Browser With WebAI, the model runs on the user’s device. That means AI requests do not need to be sent to a company’s cloud server for processing. This setup changes where the information handled by an AI feature goes. Opera says local AI use can allow people to use AI features without sending personal information to outside servers or paying for a cloud-based AI subscription. The company describes the model as giving users more control over the AI operating on their computer. Still, processing AI locally does not remove every privacy risk. ## Why Opera Is Focusing on Open-Weight AI Models Open-weight models are generally available to download and use without charge. Their model weights are publicly available, which can give developers more room to modify how the models operate. They are not the same as fully open-source software. Open-weight models can still carry restrictions, even when their underlying weights are available. Opera says WebAI is designed to support a range of these systems instead of being tied to a specific model. Google’s Gemma is one model Opera has identified as compatible with the standard. On Mac devices, Opera says WebAI can also support Apple’s on-device foundation model. ## Privacy Considerations for Browser-Based AI As AI assistants gain access to more personal information, questions about how that information is stored and used have become more prominent. People can share substantial amounts of personal data with AI chatbots, sometimes without fully understanding where that information goes. Local AI offers a different approach because the processing occurs on the device itself rather than on a company’s cloud server. According to Opera, this can give users more control over their information. Opera has also promoted digital privacy as part of its browser offering over the years. WebAI extends that focus to AI tools by keeping the local AI processing on the user’s own computer. ## What WebAI Could Mean for Developers Opera says developers can add AI features without operating AI infrastructure or paying for each request. Because the AI model runs locally, developers would not need to depend on cloud processing for those features. The company frames WebAI as a way to make browser-based AI features available without requiring users to maintain an AI subscription. In Opera’s description, users can keep the information handled by the local AI on their own device while retaining control over the AI running on their computer. ## Local AI Performance Depends on Hardware Running AI models locally involves a trade-off. The work is handled by the user’s computer, so it can place greater demands on the device and affect performance. Opera notes that model performance depends on the hardware available. A device’s capabilities will influence how well a locally run AI model performs in the browser. That’s the practical side of local AI: more processing stays on the device, but the device also has to carry the workload.
