Personalized LLMs can share most adaptation capacity across users, needing only tiny per-user code.

LINEUP learns shared low-rank factors and composes them per query, reducing per-user parameters from 4.19 million to 8 scalars while outperforming baselines on all 12 metrics.

The authors revisit personalized adaptation for large language models by asking how much of a personalized adapter is actually personal.

The authors conducted three complementary empirical analyses on personalized LLM adapters.
