Key quotes
Brave Software has introduced a new privacy feature for its AI assistant, Leo, enabling cryptographically verifiable privacy and transparency using Trusted Execution Environments (TEEs) backed by Nvidia hardware.
The new system marks a significant step toward transitioning away from blind trust in AI providers toward a “trust but verify” model
Brave’s transparency mechanism allows users to verify which model is being used, helping counter this practice and supporting accountability.
The feature utilizes NEAR AI infrastructure and Nvidia’s Hopper GPU architecture to isolate AI inference in secure enclaves. Initial rollout is available for the DeepSeek V3.1 model in Brave Nightly.
