This benchmark ranks world and video generation models on whether they can move the camera to a place defined by the scene itself, such as behind the sofa, into the driver’s seat or to the dog’s point of view, starting from a single still image. The rankings are updated continuously from 955,708 responses across 158,383 pairwise human-preference matches. Quality is decomposed into capability dimensions: a fixed, curated prompt set paired with a single criterion, fitted with a Bradley–Terry model on the Elo scale. All data and judgments are public.
We evaluate generative model performance purely on human feedback. Humans perform inconsistently on absolute judgements, but much better in a comparative setting. Our rating is therefore based on pair-wise matches, the results of which are jointly fit using the Bradley–Terry model where the probability of model m beating model m′ is given by:
A match pairs outputs from two models for the same prompt. As evaluating all permutations is infeasible, matches are sampled, ensuring broad coverage per model. The resulting scores are scaled to the familiar Elo range via Rm = 400 βm + 1000 (2), which stretches standard Elo by ln 10 ≈ 2.3 to better highlight differences in model capability.
We wrote 220 camera instructions for 50 scenes, each placing the camera relative to what its scene contains rather than along a stated direction, held fixed to ensure reproducibility of the results.
To ensure trustworthy ratings we employ several measures, notably annotator pre-filtering via gold-standard questions, and redundancy, collecting a minimum of m responses per match (m = 5) and deciding the winner by majority. Read more
We use crowd intelligence to deliver real, diverse human feedback at scale for model evaluation and post-training.
