GregBench 1.0. Cost is estimated from each run’s tokens at Cursor’s list prices. Time is the model’s own time across the six prompts. See the prompts.

GregBench 1.0

Six prompts in one conversation: running, other gaits, a 3D turn, natural behavior, Halloween costumes, and the ringtail in every costume.
Nine North American animals and three reference sprites. Prompt 1 uses five animals, and prompts 2 and 3 use the other four.
Each prompt now names an output folder, so every model saves its gifs in the same place.
Prompt 2 gained the {animal_name}-motion.gif file name format, and prompt 6 asks for the ringtail only.
Fixed two typos in the prompts: "gits" is now "gifs" and "preforming" is now "performing".
