antirez: An LLM's Hidden State Isn't Its Full Representation — It's Not an Encoder

antirez · x · 2026-11-04

antirez offers a key clarification in the JEPA vs LLM debate around the platonic representation hypothesis: an LLM's hidden state does not carry the model's full internal representation—only what's needed to predict the next token. An LLM is not an encoder, so its hidden states can't be directly compared with JEPA's learned representation spaces.
