New research paper details "pigeonholing" effect in LLMs

A new research paper introduces the concept of "pigeonholing," where suboptimal or incorrect prompts can degrade the performance of large language models (LLMs) and lead to mode collapse. This phenomenon occurs when models repeat incorrect information from the conversation history or converge on limited responses, even when provided with correct examples. The study demonstrates that pigeonholing worsens with increased conversation turns and proposes a mitigation strategy called RLVR with synthetic errors, which significantly improves model performance under adverse contexts.

IMPACT Highlights a vulnerability in LLMs to suboptimal prompts, potentially impacting reliability and requiring new mitigation techniques.

    Pigeonholing: Bad prompts hurt models to collapse and make mistakes

    While in-context learning is generally shown to be effective in Large Language Models (LLMs), bad contexts can cause performance degradation and mode collapse, a phenomenon we call "pigeonholing." **Unintentionally bad** contexts can happen without malicious jailbreaking intents:…
