Three months ago DATE , Brave previewed Leo PERSON —the browser-native AI ORG assistant—on its Nightly WORK_OF_ART channel for developers and testers. Since then we’ve seen great adoption, with tens of thousands CARDINAL of users globally. With user feedback, we’ve been able to improve much faster than we’d hoped—on response-times, the quality of responses, even the product UI ORG . Today DATE , we’re excited to announce that Brave Leo ORG is ready for all Brave users, available in desktop release 1.60 CARDINAL .

With that testing, we also received requests for new features. The most common one has been to add different AI language models in Leo PERSON .

What is Brave Leo?

Leo, Brave ORG ’s browser AI assistant, can help with all sorts of tasks. It can create real-time summaries of webpages or videos. It can answer questions about content, or generate new content. It can even translate pages, analyze them, rewrite them, and more. Whether you’re looking for information, trying to solve a problem, or creating content, Leo PERSON can help.

Leo PERSON combines this easy, free access to AI with the privacy focus of Brave. Chats with Leo PERSON are private, anonymous, and secure. Leo PERSON doesn’t record chats, or use them for model training, and no account or login is required to use Leo PERSON . With cutting-edge technology and privacy, Brave Leo PERSON pushes the boundaries of typical AI ORG chatbot services.

“It is increasingly common today DATE to use AI to ask questions and get assistance. AI can be a powerful tool but it can also present growing concerns for data privacy and there’s a need for a privacy- first ORDINAL solution,” said Brian Bondy PERSON , CTO and co-founder of Brave. “Brave is committed to pairing AI with user privacy, and will provide our users with secure and personalized AI assistance where they already spend their time online. We’re also thrilled to work with Anthropic ORG to bring Claude PERSON ’s exceptional conversational abilities to the millions of Brave MONEY users worldwide.”

Introducing Leo Premium

By default, Brave Leo ORG is free for all users, with easy access to the Llama 2 LAW large language model from Meta ORG . For users who want additional models, Brave is also releasing a premium version of Leo PERSON for $ 15/month DATE . Leo Premium PERSON subscribers will get access to Claude Instant PERSON , Anthropic ORG ’s faster and lighter model that excels at logical reasoning and coding. The current version of Claude PERSON produces longer, more structured responses, follows instructions better than previous versions of Instant, and shows improvements in math, coding, multilingual abilities, and question answering. Additional models will be available to Leo Premium ORG users, as well as access to higher rate limits, higher-quality conversations, priority queuing during periods of peak usage, and early access to new features and improvements.

This integration represents a milestone in delivering sophisticated natural language conversations powered by AI directly within the browser environment. With Claude PERSON ’s advanced capabilities and Brave ORG ’s focus on user privacy and control, we hope to set a new standard for helpful, responsible, and context sensitive AI interactions. Anthropic used Brave’s Search API to train their latest model, Claude 2 PERSON , on high-quality data to help optimize Claude PERSON ’s outputs for retrieval augmented generation (RAG) queries.

“We’re excited that Brave is going to bring our state-of-the-art large language model Claude PERSON Instant directly into their browser. Integrating access to Claude PERSON seamlessly within Brave ORG gives users assistance whenever they need it, right in the context of the page they are on,” says Matt Bell PERSON , Head of Product Research at Anthropic. “ Whether Brave WORK_OF_ART users are analyzing text, editing documents, or writing code, they can now benefit from having personalized help from Claude PERSON at any time. This integration unlocks the potential for AI to enhance people’s browsing and productivity in an intuitive, contextual way.”

Brave Leo and unparalleled privacy

As a privacy- first ORDINAL company, Brave ORG is dedicated to releasing leading alternatives to popular Web tools that also protect user data and anonymity. Leo PERSON is no different:

Reverse proxy : All requests are proxied through an anonymized server so the request and user-address cannot be linked. Brave cannot associate the user request with their IP address.

Immediate discarding of responses : Conversations are not persisted on Brave ORG ’s servers. Responses from Leo PERSON are discarded immediately after they’re generated, and not used for model training. We do not collect identifiers such as your IP Address that can be linked to you. No personal data is retained by the AI ORG model or any 3rd ORDINAL -party model providers.

No login or account required for access : Users do not need to create a Brave account to use Leo PERSON .

Unlinkable ORG subscription: If you sign up for Leo Premium PERSON , you’re issued unlinkable tokens that validate your subscription when using Leo PERSON . This means that Brave can never connect your purchase details with your usage of the product, an extra step that ensures your activity is private to you and only you. The email you used to create your account is unlinkable to your day-to-day use of Leo PERSON , making this a uniquely private credentialing experience.
