Modifications

The upstream checkpoint is remapped into LibreYOLO's native V-JEPA 2 module and wrapped with LibreYOLO v1.0 checkpoint metadata (family, size, task, dataset variant, clip geometry, preprocessing and the pooling rule). Tensor values are unchanged: the conversion is a key remap, loaded strictly, and the self-supervised predictor tower is dropped as a named, asserted set rather than by substring match.

Parity against unmodified transformers==5.1.0 on float32 CPU is exact (max_abs_diff == 0.0) for single-view logits.

Embedding contract

This probe applies the exact upstream three-layer attentive pooler and linear classifier. One temporal view is used by default; the published multi-view accuracy is NOT claimed from single-view inference.

V-JEPA 2 is trained on video. An image is accepted as a single-frame input, which is a static appearance representation, not a motion one.

The probe was trained on a third-party video dataset, named for provenance only. Its dataset terms are not the terms of these weights, and LibreYOLO does not mirror or auto-download it.
