Study Finds VGGT Internally Knows When Its 3D Reconstructions Fail

A new arXiv paper shows that feedforward 3D reconstruction model VGGT, though it reports no pose uncertainty, encodes self-knowledge in its internal features: linear probes predict its failures with 93.5% ROC-AUC, flagging 35% of failures on the HardMatch benchmark.
