Every upload is scored on two custom engagement metrics and nine raw neural networks from Meta's TRIBE v2 model. Here's what they mean and how they're computed.
How strongly your content engages the brain in the opening 10 seconds — the window where viewers on short-form feeds decide to stay or scroll. We average predicted activation across all nine networks over the first five 2-second segments.
Above 0.40 is strong. Drops below that range are the most common weak-hook signal.
