DeViL is a detector-empowered video large language model designed for efficient spatio-temporal video grounding (STVG) and grounded video reasoning. Instead of relying on long autoregressive coordinate decoding or expensive candidate construction, DeViL offloads dense spatial grounding to a fully parallel detector. It distills the user query into a detector-compatible reference-semantic token and uses temporal consistency regularization to maintain object coherence across frames.
This repository hosts the official DeViL-7B checkpoint released by the authors.
