Overview

4D-RGPT-8B is an NVIDIA video-text model focused on region grounding, 3D reasoning, and 4D reasoning. Those capabilities are important when an agent needs more than a clip-level summary. The agent needs to know which region changed, where the object moved, and how the event evolved over time.

On Mixpeek, 4D-RGPT can enrich video indexes with region-grounded temporal evidence. It is a fit for robotics footage, surveillance review, sports clips, and operational video where the retrieval result must preserve spatial and temporal context.

Architecture

NVILA-Lite-8B based video-text-to-text model. The Hugging Face metadata tags it for video understanding, region grounding, 3D reasoning, 4D reasoning, and perceptual distillation.
