All LLMs converge on a universal geometry of meaning, study shows — embeddings can be translated and inverted

Researchers show that large language models are converging on the same "universal geometry" of meaning. They developed a method to translate between any model's embeddings without paired data, encoders, or the original text — despite different architectures and training sets, the models share a latent structure of human meaning, mathematically confirming the Platonic Representation Hypothesis.
The finding also exposes a risk for vector databases: embeddings can be translated and inverted, enabling data extraction without hacking the model itself.
