Nvidia Cosmos 3 | Hacker News

Hacker News users discussed Nvidia Cosmos 3, a 64B open-source image and video generation model.

Commenters said it outperforms several rival open models, but it is still behind some frontier systems.

The model is too large for most personal hardware, limiting local use.

Discussion also centered on its role in synthetic data and world modeling for physical AI, including robots, cars, and drones.
