*Equal contribution. †Corresponding author.
GeoFlip includes first frames, video-generation prompts, simulation references, evaluation labels, baseline predictions, and scoring code. Alongside the 964 core conditions, 16 neutral controls are provided separately, for 980 conditions in total.
Quick start
Follow the scoring quickstart. To use the toolkit included with this dataset:
python -m pip install -e './toolkit[download,video,http]'
Download scripts support model inputs only, evaluator metadata only, or the complete package, pinning one HF commit and verifying SHA-256 checksums. Give the model only inputs/manifest.jsonl fields and the selected first frames. Never provide evaluation truth or reference futures to a generator.
To score existing generated videos, create a submission JSON mapping each opaque condition id to a native video file. Validate, obtain event/structure judgments, and run the deterministic scorer.
geoflip validate --data . --subset paper-main --submission my-model/submission.json --out validation.json
geoflip score --data . --subset paper-main --predictions my-model/judgments.jsonl --out scores.json
geoflip baselines --data . --subset paper-main --judge gpt-6-astra --out reproduced-main.json
The last command reproduces the event and structure scores of all 16 paper models without API calls. All 32 main-table values match after rounding.

16 | Neutral controls, separate from the core count |

Use the fixed ID lists in splits/ for comparisons. Original partitions and pair information are recorded in the evaluator metadata.
Metrics and prompts
Event correctness is class-balanced within each task and then task-macro averaged. Structural integrity is the task-macro fraction explicitly judged clear; uncertain, flagged and missing outputs remain in the denominator. See EVALUATION.md.
Generation prompts are in inputs/manifest.jsonl; judge prompts and task definitions are in prompts/. See DATA_FORMAT.md for original prompt text and video-continuation adaptations.
The paper's PSNR/SSIM columns use a separate 40-clip benchmark. Those aggregate numbers are preserved, but that benchmark's reference media are not redistributed here. GeoFlip reference-similarity diagnostics are labeled separately and must not replace the 40-clip values in the paper ranking.
Usage terms
Dataset usage terms are in LICENSE.txt.
The paper's Opus evaluation was run separately; its raw judgments are not included here. Additional historical predictions are identified as Qwen3-VL-32B-Instruct according to their source metadata. These are separate results. The included GPT predictions reproduce all 32 main-table event/structure values.
