SummaryA research paper proposes the Atomic User Model (AUM), a human-readable user representation structured as an identity nucleus with four interpretable shells, used as a retrieval index rather than a prompt prefix. Evaluations with 16 LLM-simulated participants show 8 retrieved fields match full-model style fidelity at 23% of context size, with pre-registered controls isolating the effect.
Why it mattersFrames personalization as retrieval over a structured user model instead of context stuffing. Pre-registered controls and effect-size reporting make the claim auditable rather than anecdotal.
