TRIBE v2の発表：人間の脳が複雑な刺激を処理する方法を理解するように訓練された予測基盤モデル

Today, we're announcing TRIBE v2: our first AI model of human brain responses to sights, sounds, and language. Building on our Algonauts 2025 award-winning model, which was trained on the low-resolution fMRI recordings of four individuals, we leverage a massive dataset of more than 700 healthy volunteers who were presented with a wide variety of media, including images, podcasts, videos, and text. TRIBE v2 reliably predicts high-resolution fMRI brain activity — enabling zero-shot predictions for new subjects, languages, and tasks — and consistently outperforms standard modeling approaches. By creating a digital model of the human brain, researchers can rapidly test hypotheses about its underlying functions without the need for human subjects in every experiment.

To accelerate the pace of neuroscience discovery and open up new avenues for clinical practice, we’re sharing a research paper, along with model weights and code, under a CC BY-NC license. We also invite everyone to explore TRIBE v2 on our demo website. By sharing this work, we hope to help accelerate neuroscience research that will unlock scientific and clinical breakthroughs for the greater good.
