Key quotes

Brave Leo is a chat assistant hosted by Brave without the use of third-party AI services
The model behind Leo is Llama 2, a source-available large language model released by Meta with a special focus on safety.
Chats in Leo cannot be used for training purposes, and no one can review those conversations, as they’re not persisted on Brave’s servers

The announcement details Leo’s integration into the Brave browser sidebar, allowing users to summarize articles and interact with web pages. It emphasizes anonymity through a reverse-proxy and the absence of persistent storage for chat history.
