# How do the driving and robot world-model sources measure multi-view, temporal, physics and control-following consistency, and which of those measurements are numbers versus figures or company claims?

The sources use five families of checks: distribution distances (FID, FVD, FDD, FVMD), epipolar Sampson error within a view over time (TSE) and between views (CSE), pose re-estimation from the generated clip to check commanded paths (Cosmos TAE/TFE and camera-path errors, Vista IDM trajectory difference), detector/segmentation agreement with the conditioning boxes (GAIA-2), and human preference tests (Vista, Cosmos instruction tests). GAIA-2 provides no multi-camera metric in its text; Cosmos does (TSE/CSE, Table 24 and Predict2.5 Table 14) and notes the real-video reference values. Wayve's GAIA-3/4 pages describe LiDAR alignment, a three-level fidelity scheme and unpublished correlation claims; these are company statements without a linked report. Numbers from different reports are not comparable even for similar model names.

Curator qualifications: Five families of checks: distribution distances, epipolar errors, pose re-estimation of commanded paths, detection/planning downstream, human preference.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
