# SANA-WM

SANA-WM is a 2.6B-parameter world model from NVIDIA's SANA team that follows a 6-DoF camera path for up to a minute of 720p video. A streaming variant and a hosted demo are available; the optional refiner builds on LTX-2.

Organization: NVIDIA (SANA team). Released: May 2026. Kind: Explorable world.

## What you control

- A starting image and prompt
- A 6-DoF camera trajectory
