Brave Software has implemented Trusted Execution Environments (TEEs) for its AI assistant Leo, enhancing privacy for users of its cloud-based AI services. Currently, TEEs are available exclusively to users of Brave Nightly, the testing version of the browser, for the DeepSeek V3.1 model. This feature aims to ensure the confidentiality and integrity of user data processed in the cloud.
