fraction

What this part means

Divide the expression above the line by the one below it.

Its job in the formula

The expression above the fraction bar is divided by the complete expression below it. The denominator must not be zero.

The passage around this formula

The image-text tokenization scheme has an exact, well-understood cost. An image of height H and width W , cut into square patches of size P , produces Ntok=HP⋅WPN_{\mathrm{tok}} = \frac{H}{P} \cdot \frac{W}{P}. tokens. Video adds a third factor. If a model attends over T sampled frames, each cut into the same spatial grid, and groups PtP_t consecutive frames per temporal patch, the token count becomes
