Brave's Leo Structure Explained

Like ChatGPT, Bard, or any other text assistant, even Leo is built on an open large language model (LLM) Llama 2, powered by Microsoft and Meta. Some other specifications include the following:

  1. Natural Language Processing (NLP): The chat assistant is powered by Natural Language Processing models, which help it understand and assimilate human commands, language, and commonly used terms. Since NLP is used for bridging the distance between a computer and a human, it has found widespread use within the world of AI.
  2. Machine Learning: Leo is trained on various text datasets to help it improve its answers and widen its knowledge base. With machine learning algorithms under its belt, it can access knowledge repositories and build upon user interactions to understand the question's intent and answer in a relevant manner.

As per Brave's developers:

We’ve specifically tuned the model prompt to adhere to Brave’s core values. However, as with any other LLM, the outputs of the model should be treated with care for potential inaccuracies or errors.

What Does Brave’s Leo AI Chatbot Offer?

As expected, Leo's AI features are something to reckon with. Its list of features is as follows:

  1. Summarization Qualities: Why go through extensive website content when your browser can provide a crisp, summarized gist in just a few clicks? That's right; Leo's ability to summarize a website's contents is a handy feature. Brave's text assistant offers you plenty of opportunities to summarize the entire search criteria or the content on individual web pages.

  2. Helpful Answers: You can seek answers from Leo, Brave's browser AI assistant, whenever you have questions. Like ChatGPT, even Leo provides accurate solutions. Since it's still in the testing phase, there is a lot of ground for it to cover. Nonetheless, after the final release of the stable version, Leo will become a preferred AI tool for Brave's users.
  3. Flag security issues: Since Brave browser is known for its security preferences, the utmost focus is always on keeping users safe and secure. If you notice a security breach or any inherent issues within Brave or its dependent components, you can flag it to Leo, and it will raise it to the concerned teams for rectification. Leo, unlike ChatGPT, does not record your previous conversations; whenever you reload your chat, you start your conversations afresh.

Limitations of Brave’s Leo

Despite all the positive elements of Leo, there are a few inherent limitations that you need to keep in mind. Here are a few things to look out for:

  1. Limited Knowledge: Leo's developers have issued a caveat regarding its knowledge and answer-sharing model. While its training is extensive, there are still a few things Leo might need to learn about. Since the underlying AI model grows with interactions, it's yet to develop to its fullest potential.
  2. Ability to Reason: It's essential to remember that Leo is a text-based AI assistant at the end of the day. At the same time, it can provide answers and solid matches for your questions, but can't react and provide arguments like a human. In short, its ability to reason is limited in scope.
  3. No Experience With Sarcasm and Humor: Leo is an artificial intelligence-driven assistant and should not be considered more than that. There are limited inputs, which do not include access to sarcasm or humor.

Leo AI, Brave’s Text Assistant, Competes Against Other Options

Let's face it: plenty of new AI tools appear daily. Brave isn't far behind, for Leo is its answer to its competitors. Despite being in training, it continues to garner attention from the browser's users, who are keen to see what final features Leo brings within the stable version.
