TRIBE v2 Neuroscience

In-silico neuroscience using Meta FAIR's TRIBE v2 — predict fMRI cortical responses to video, audio, or text using a single pretrained transformer. Run experiments on any hardware, without a scanner.

What TRIBE v2 Is

TRansformer for In-silico Brain Experiments (v2) is a brain encoding model released by Meta FAIR on March 26, 2026. It is not a language model — it predicts fMRI BOLD responses on the fsaverage5 cortical surface (~20,000 vertices per hemisphere) given multimodal sensory input.
