About TRIBE v2

TRIBE v2 is Meta AI's open foundation model for predicting human brain activity in response to naturalistic stimuli (video, audio, text). It pairs V-JEPA2 (video), Wav2Vec-BERT (audio), and LLaMA 3.2 (text) encoders, was trained on 1,000+ hours of fMRI from 720 subjects, and delivers a ~70× resolution improvement and 2–3× accuracy gain over previous methods — including zero-shot prediction for individuals it has never seen. Meta released model weights, codebase, paper, and this interactive demo so researchers can run in-silico neuroscience experiments without scanner time. CC BY-NC licensed.
