AI models, particularly transformers, utilize high-dimensional embeddings to represent words and their contextual meanings. While humans intuitively grasp 3 dimensions, AI models operate in spaces with hundreds or even thousands of dimensions, such as the 512 dimensions in the original Transformer architecture. These dimensions, though not directly interpretable as specific concepts, allow models to encode rich information about tokens and their relationships. The superposition principle further enhances this capability, enabling neural networks to represent more features than their neuron count by allowing multiple concepts to overlap within activation spaces.
