New research explores decoding text from LLM representations and adaptive generation

By PulseAugur Editorial · [2 sources] ·

Two new research papers explore novel methods for decoding information from large language models. The first, "Next Token or Vector? Learning How Far to Decode," introduces CADENCE, a generation method that adapts the granularity of token prediction, achieving up to 1.3x higher throughput than standard greedy decoding. The second paper, "Rep2Text: Decoding Full Text from a Single LLM Token Representation," presents a method to reconstruct text from a single hidden representation, finding that these representations retain significant information and highlighting potential privacy risks. AI

IMPACT These papers offer new insights into LLM internal representations and generation efficiency, potentially impacting future model development and privacy considerations.

    Next Token or Vector? Learning How Far to Decode

    arXiv:2610.22788v1 Announce Type: cross Abstract: Standard autoregressive decoding advances one token at a time, even when several upcoming tokens can be predicted together. We propose CADENCE (Context-Adaptive DEcoding), a generation method that learns both what to draft and how…

    Rep2Text: Decoding Full Text from a Single LLM Token Representation

    arXiv:2511.06571v4 Announce Type: replace-cross Abstract: Large language models represent text as hidden numerical patterns, but what information these representations actually contain remains a mystery. Can we recover the original text from just one of them? In this paper, we in…
