What are AI ‘world models,’ and why do they matter?
Explore AI world models, investments in them, and their potential uses.

World models, or world simulators, are based on the mental models humans naturally develop, offering foundational concepts crucial for AI. These models aim to reproduce human-like reasoning by predicting future actions and understanding their environment, prompting significant interest from organizations like World Labs, which raised $230 million, and DeepMind, known for hiring top talent to further this research.
A practical application of these models can be seen in generative video, where they excel in simulating realistic video sequences by understanding the physics and dynamics of the environment. For instance, OpenAI's Sora can simulate video games like Minecraft, showing promise for future 3D world generation applicable in gaming and virtual photography.
Despite their potential, world models face hurdles like massive computational needs and the risk of embedding biases found in their training data. These models require extensive and varied datasets to function effectively, particularly as they aim to enhance AI's ability to interact with and make decisions in the real world, including future advancements in robotics and AI decision-making.
