Image captioning with zero image-text pairs: one rotation maps DINO features into text space

randall_balestr · x · 2026-10-30

Follow-up on the PRH theorem thread: the authors fine-tuned a small LLM decoder on text only, on top of their text-JEPA. A photo goes through a DINO encoder, one rotation maps it into text space, and the decoder describes it — no network was ever trained on image-caption pairs. Sample captions shown in the post.
