Cosmos | Code | Paper | Paper Website

Model Overview

Description:

Cosmos World Foundation Models : A family of highly performant pre-trained world foundation models purpose-built for generating physics-aware videos and world states for physical AI development.

The Cosmos autoregressive models are a collection of pre-trained world foundation models that are ideal for predicting and rapidly generating video sequences from video or image inputs for physical AI. They can serve as the building block for various applications or research that are related to world generation. The models are ready for commercial use under NVIDIA Open Model license agreement.

Model Developer : NVIDIA

Failure Analysis

Our models now support video extension up to 33 frames. Starting from either a single image or a 9-frame video input, it can generate the remaining frames to reach the 33-frame length (generating 32 or 24 frames respectively).

We have evaluated all eight possible configurations (4 models × 2 vision input types: image or video) using 100 test videos from physical AI domains. Below are the failure rates for each configuration:

We define failure cases as videos with severe distortions, such as:

• Sudden appearance of large unexpected objects
• Video degrading to a single solid color

Note that the following are not considered failures in our analysis:

• Static video frames
• Minor object distortions or artifacts
