# How should an agent read FID/FVD tables on nuScenes for driving world models, given that one paper reports two sets of numbers for the same method and later papers copy different ones?

The same method (DriveDreamer) has two published nuScenes results: FID 52.6 / FVD 452.0 in arXiv v1 and FID 14.9 / FVD 340.8 in v2, with the DriveGAN baseline also changing (73.4 / 502.3 to 27.8 / 390.8). Vista's Table 2 reuses the v1 pair; DriveDreamer-2's Table 1 uses the v2 pair. Vista says no prior model was publicly accessible, so cross-paper comparisons are of reported numbers, each under its own sampling, resolution and conditioning protocol. Downstream detection/tracking gains (mAP, NDS, AMOTA with generated training data) are an additional, task-based check used by DriveDreamer and DriveDreamer-2. A ranking claim from a table is only as good as the protocol match.

Curator qualifications: DriveDreamer has two published nuScenes results (v1 FID 52.6/FVD 452.0; v2 FID 14.9/FVD 340.8) and later papers cite different versions (matches curator check in C3R-0380).
