Language Models are Injective and Hence Invertible (ICLR 2026), aka “pringle paper", is now a public graph on
@paradigmainc’s Flywheel
In the paper, we show that LMs can be inverted and, contrary to common belief, do not discard information about their inputs at inference time.
LLMs are injective and invertible.
In our new paper, we show that different prompts always map to different embeddings, and this property can be used to recover input tokens from individual embeddings in latent space.
