Withdrawn arXiv paper analyzed LLM adapter merging and reasoning trace leakage

A research paper, since withdrawn by its author Junyi Zou, explored the phenomenon of latent reasoning traces reappearing in large language models after adapter merging. The study, conducted in medical LLM settings, introduced novel methods for measuring trace leakage and instruction-following behavior, including a marker-forbidden, answer-only evaluation. The authors also provided geometric evidence of misaligned update directions between domain and instruction adapters and demonstrated a proof-of-concept geometry-aware merge to mitigate leakage and improve accuracy.

    Adapter Merging Reactivates Latent Reasoning Traces: A Mechanism Analysis

    arXiv:2601.18350v5 Announce Type: replace-cross Abstract: Large language models fine-tuned via a two-stage pipeline (domain adaptation followed by instruction alignment) can exhibit non-trivial interference after adapter merging, including the re-emergence of explicit reasoning t…
