Brave Installs Mistral’s Mixtral as Default LLM for Generative AI Browser Assistant Leo
Brave has augmented its generative AI assistant Leo with Mistral AI’s Mixtral 8x7B large language model (LLM). The French startup’s LLM will serve as the default model for Leo, enhancing its existing abilities and adding new abilities to the virtual web companion.
Leo launched a few months ago with Meta’s open-source Llama 2 LLM, fueling its responses to questions, website summaries, and text composition. Brave always envisioned Leo as having a stable of LLMs to turn to, but the automatic first choice now will be Mixtral 8x7B. Mistral released the ‘open-weight’ model in December, gaining plaudits for speed and outperforming LLMs like OpenAI’s GPT-3.5 and Anthropic’s Claude Instant in various benchmarks. That performance led Brave to pick Mixtral as the Leo default. LLM.
Mixtral also gifts Leo with additional benefits like an expanded context memory, multilingual understanding, and translation among English, French, German, Italian, and Spanish. It can also write compute code upon request, extending the Mixtral-powered CodeLLM feature in the Brave Search search engine.
“Since its release, Brave Leo has been adopted by tens of thousands of free tier users and paid subscribers, and we expect even greater adoption as we expand our availability of LLMs to include Mixtral,” Brave CTO Brian Bondy explained “Our aim is to create novel and convenient use cases in the context of users’ browsing sessions, and to help our users interact with the Web in groundbreaking ways.”
Though Mixtral 8x7B serves as the default LLM for Loe, the assistant has other models that users can choose based on their needs and budget, including Claude Instant and Llama 2. The free version of Leo is rate-limited, but a $15 monthly premium subscription ups those limits, among other benefits. For those using the free version, there is also the option to revert to the previous Leo experience with Llama 2 once they reach the rate limits for Mixtral.
“We are very happy to see Mixtral being used to power CodeLLM in Brave Search, and to now have Mixtral integrated in Brave Leo,” Mistral AI CEO Arthur Mensch said. “Making Mixtral available as an open model enables Brave to easily integrate it and to fulfill their users’ growing AI needs.”
Web browsers are starting to adopt generative AI at an accelerating pace. This week saw Google Chrome announce several new generative AI features to enrich the browser. Opera has been one of the quickest to infuse LLM-powered features through its Aria generative AI assistant. Opera has been steadily adding new generative AI tools through Aria since its launch. Aria recently gained the ability to learn to mimic a user’s writing style based on submitted examples, which the privacy-centered Brave would be less likely to include.
