Meta Releases TRIBE2 to Predict Human Brain Activity

Meta introduced TRIBE2, an AI model that predicts human brain responses to sights and sounds, replacing slow and costly brain recordings. It acts as a “digital twin” of the brain, turning months of neuroscience experiments into seconds of simulation. Using tri-modal inputs (audio, video, text) and transformer-based integration, it maps activity to fMRI-like brain signals. Trained on 500+ hours of data from 700+ people, it enables faster, scalable, and often accurate brain research.
