Visual comparison

Sample videos

Only runs from both exact model versions under the same archived prompt and first-output rule appear here. Provider showcases and substitute versions remain excluded.

Controlled practical comparison. Both exact model versions received the same archived prompt in one request. The first output counts. Playback uses the first five seconds, 1280 × 720 pixels, 30 fps, no crop, and muted audio. Provider-side randomness and prompt processing remain model characteristics.

How to read the data

Preference is not the same as production fit

A higher LMArena rating means that outputs from this exact configuration were preferred more often in blind comparisons.

Motion control, identity consistency, audio, turnaround time, moderation, and licensing may matter more than the aggregate preference rating.

Prices are representative public minute rates, not a normalized cost benchmark.
