Brave joins the growing list of browsers that feature generative artificial intelligence assistants. Open source developers have now expanded the browser update for Brave on desktopwhich makes it available to users AI assistant Lea. Brave introduced Leo through its experimental Nightly channel back in August and has been testing it ever since. The assistant is based on the Llama 2 large language modelwhich Microsoft and Meta jointly developed for commercial and research purposes.

Like other AI assistants, Lea users can ask to perform various tasks, such as creating summaries of web pages and videos, translating and/or rewriting pages, and even generating new content. Leo powered by Llama 2 is available free for all users, but Brave also introduced a paid version capable of higher quality conversations. This version is called Leo Premium and is powered by the Anthropic Claude Instant system, its specificity is that it can generate longer and more detailed answers. Users will have to pay $15 a month for it, but they’ll also get priority queuing at peak times and early access to new features.

Brave Software emphasized in its announcement that Leo preserves user privacy. The developer said that conversations with Lee are not stored on its servers and that the assistant’s responses are immediately discarded and not used to train the model. It also explained that it does not collect IP addresses or store personal information that could identify users. Plus, users don’t even need to create an account to use Leo.

However, back in July, Brave came under fire after it was accused of being non-consensual sells copyrighted information to train artificial intelligence models. “Brave Search has the right to monetize the outputs of its search engine,” Josep M. Pujol, the company’s head of search, said at the time in response to the allegations. “The content of the web page is always an excerpt that depends on the user’s query, always with a URL address. This is a standard and expected feature of all search engines.”

Brave is rolling out Leo for desktop now. However, those using the browser on their Android and iOS devices will have to wait a few more months.
