Equation 1 · Part 3 · One Model, Many Modalities: What Multimodal Systems Actually Share

Symbol P

Ntok=HP⋅WP,N_{\mathrm{tok}} = \frac{H}{P} \cdot \frac{W}{P},
PP

What this part means

P occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.

The passage around this formula

…performs competitively with convolutional networks when pre-trained on enough data [ 2 ] . The token count follows immediately from the geometry, Ntok=HP⋅WPN_{\mathrm{tok}} = \frac{H}{P} \cdot \frac{W}{P}. for an image of height H and width W at patch size P . The quadratic relationship is the entire practical story of image tokenisation. Halving the patch size quadruples the sequence, and attention cost grows faster still. Every deployed system therefore resolves a three-way tension between input resolution, patch size, and context budget, and it…
