ProofBox

The problem: “item missing” claims are one of the costliest headaches in e-commerce, and sellers often lose them by default because they can’t prove what went into the box. What ProofBox does: an overhead camera records every mailer as it is packed. The QR label on the parcel is detected and the frame is linked to the order. YOLO tracks each item placed inside, and NVIDIA Cosmos Reason watches the clip to confirm what each item is and that it actually went in. Every verdict, timestamp and clip reference is stored in VastDB on the VAST AI OS. When a claim lands: the seller asks in plain text or by voice (“was the charger in order 4821?”) and a W&B-hosted agent returns a per-item verdict, packed or not packed, with the exact clip as evidence, ready to attach to the marketplace or payment dispute. Built on: VAST S3 + DataEngine + VastDB for ingest and the evidence store, NVIDIA Cosmos Reason and Cosmos Embed for reasoning and semantic search over packing footage, YOLO on CoreWeave GPUs for detection and tracking, Weights & Biases Inference for the agent, built in Cursor. Supply chain potential: the same pattern works at every handoff. Add cameras at pick, pack, carrier handover and returns, and each order gets a video-verified chain of custody. That gives 3PLs and brands proof for mis-pick and shrinkage disputes, carrier liability and insurance claims, plus searchable warehouse footage (“every order where an item was swapped after pick”).
