TRIBE Virality
Predicts a virality score (0–100) for short videos using Meta’s TRIBE v2 brain-encoding foundation model. TRIBE v2 predicts fMRI activation across the human cortex in response to naturalistic video, audio, and speech; this model wraps those per-vertex predictions in a cortical-proxy scoring layer that summarizes them into a single headline number plus five interpretable sub-scores.
What you get
For any short video (≤60s, MP4/MOV/WebM) the model returns:
- Headline virality score — weighted blend of the five sub-scores.
- Five sub-scores mapped to brain regions associated with each construct:
| Sub-score | Weight | Cortical proxy |
|---|---|---|
| Reward | 30% | Orbitofrontal cortex, ventromedial PFC |
| Emotion | 25% | Anterior insula, anterior cingulate |
| Attention | 20% | Visual cortex, auditory cortex, intraparietal sulcus |
| Social Relevance | 15% | Medial PFC, TPJ, precuneus |
| Novelty | 10% | Parahippocampal cortex, posterior cingulate |
- Per-step timeline of all five sub-scores at ~2 Hz, for plotting how predicted brain response evolves through the clip.
Scoring is deterministic — re-running the same file yields the same score.
Intended use & limitations
- Built for short-form social/ad creative, where the dominant signal is audiovisual + spoken language. Long clips (>60s) are not supported.
- The “virality score” is a heuristic on top of TRIBE, not a clinical or scientific measurement. It correlates predicted neural engagement with intuitions about what tends to perform on social platforms; it is not a guarantee of real-world reach, which depends on distribution, audience, timing, and platform algorithms.
- TRIBE v2 predicts fMRI for the average subject — individual responses vary substantially. Do not use for medical, diagnostic, hiring, lending, or other high-stakes decisions about individuals.
