Shared positive views turn PRH into a theorem

A 109M-parameter text JEPA trained on captions of web images reaches.184 alignment with DINOv2, exceeding every language model tested, including models up to 72B parameters. The result supports the paper’s central claim: separately trained encoders can learn a shared representation when their positive pairs describe the same world states, rather than merely sharing a training scale.

The Platonic Representation Hypothesis, or PRH, proposes that models trained on different modalities converge toward a common representation of the world.…
