DeltaTok

Efficient world modeling with delta tokens

Description

Video world models encode each frame as hundreds of tokens, exploding compute for long videos. DeltaTok from Amazon proposes delta tokens where a frame is worth one token, making generative world modeling far more efficient.

It encodes only changes between frames and supports depth and segmentation; a CVPR 2026 Highlight.

Features



Delta tokens:One per frame.

Efficient:Long videos feasible.

Multi-task:Depth and segmentation.
