Ratings come from the LMArena: people see two videos for the same prompt without knowing which model made them and pick the better one. Many such picks add up to a rating, higher is better. Text to video and image to video are separate lists and are never added together.
“Ahead” means one model stays clearly higher even with the rating’s uncertainty. “Slightly ahead” means its value is higher but the gap is not certain yet. Otherwise both count as level. Places count only the models of our comparison.
Prices and clip lengths come from the providers’ documentation. From a factor of 1.25 a model counts as cheaper or longer, below that as about the same.
