‘World models’ are AI’s latest sensation: what are they and what can they do?

World models, like Nvidia's Cosmos, trained on physics data could help build better AI-controlled robots. Credit: NVIDIA Corporation An ongoing trend in artificial intelligence (AI) could have huge implications for how the technology is used in research. Machine-learning systems such as large language models (LLMs), which turn prompts into text, images and video, are becoming increasingly sophisticated and continue to make astonishing progress, including in science . …
