Jack Wallen/ZDNET ZDNET’s key takeaways Opera is releasing an important AI feature. Local AI is now getting built right into the web browser. There’ll be no need to configure or install the likes of Ollama. Opera just made a bold choice: Thanks to the newly proposed WebAI web standard, the company will soon be shipping local AI models with its browser. By doing so, Opera’s AI ensures that your queries and/or data remain on your machine.

According to Opera, because this new feature uses open-weight AI models, anyone can build on top of those models without running expensive AI infrastructure or paying for every request. That equates to more innovation for the Opera browser.

This is a bigger deal than you might think.

Most browsers include AI that depends on the cloud for responses; a user’s data is not limited to the local machine and could be used by third-party organizations to train LLMs or even build profiles.

Opera aims to resist that trend by leaning into local AI, made possible by open-weight models that have become smaller and more capable, while hardware continues to become more powerful.

“A lot of what people want from AI doesn’t need a data center. Your laptop can already do it, without sending your data anywhere,” said Krystian Kolondra, EVP Browsers and AI at Opera. “We first shipped local models to developers in 2024. Now we’re bringing them to everyone. More models and tools are coming, and you’ll always decide what runs on your machine.”

Opera also plans on bringing more open models optimized for specific devices, as well as more tools to make it easier to build browser experiences on local AI.

WebAI is a newly proposed web standard (backed by companies like Google and Microsoft) that allows websites and extensions to use browser-hosted AI. Opera’s implementation of WebAI is model-agnostic and built around open-weight models, so users can select models from the likes of Google and Apple.

WebAI is also opt-in; nothing is downloaded until the user does so. Developers can check out example extensions that use WebUI from WebAI: Local AI for the web, now in Opera.

I’ve been a fan of the Opera browser for a long time — it has served as my default for the past five years on Linux, MacOS, and Android.

I’ve seen Opera features come and go, but the good ones always stick around. Opera was one of the first browsers to integrate AI into the UI, making it very easy (and free) to use. The longer I use AI, the more one particular issue has become my calling card — local AI.

I’m a champion of local AI, and that’s the hill I will die on.

The problem thus far is that using local AI with browsers isn’t always easy. Firefox made it possible with Smart Window, but it’s not set up to use local AI by default. (You have to choose a custom provider and have Ollama installed and running on your machine.)

Opera is ready to make this reality even easier.

To try the local-first version of Opera, do the following:

According to Opera, WebAI is an early preview, available on Windows PC (64-bit, Intel/AMD) and Macs with Apple silicon. It isn’t available on Intel-based Macs, Linux or Windows on Arm.
