Vila Model Card

Description

NVIDIA Vila is a leading vision language model (VLMs) that enables the ability to query and summarize images and video from the physical or virtual world. Vila is deployable in the data center, cloud and at the edge, including Jetson Orin and laptop by AWQ 4bit quantization through TinyChat framework. We find: (1) image-text pairs are not enough, interleaved image-text is essential; (2) unfreezing LLM during interleaved image-text pre-training enables in-context learning; (3)re-blending text-only instruction data is crucial to boost both VLM and text-only performance.

This model is ready for commercial use. It was trained on commercial images and videos for all three stages of training and supports single image and video inference. This version does not support interleaved and in-context learning capabilities.
