LATENTLENS: training-free method decodes what image tokens mean inside LLMs
burkov · x · 2026-11-13
VLMs typically map image features into an LLM's representation space via a small connector, but what image-derived tokens actually mean inside the model has been opaque—possibly due to interpretation tools rather than the models. LATENTLENS is a training-free method that compares image-token representations against contextualized word representations in the LLM, searching a large index of in-context text embeddings rather than isolated vocabulary entries, offering a clearer path to explaining visual information processing and improving reliability.
