LLMs perform well with reduced context, avoiding 'context pollution'

A new research paper explores the impact of context length on large language models (LLMs) in multi-turn conversations. The study found that LLMs can maintain response quality while using significantly less context, often achieving similar performance with 8x less data by summarizing or retaining only the most recent user-assistant exchange. The research also identified a phenomenon called "context pollution," where errors or stylistic artifacts from the model's own previous responses can propagate and negatively affect subsequent turns.

IMPACT Suggests optimizations for LLM conversational agents, potentially reducing computational costs and improving response consistency.

    Do LLMs Benefit From Their Own Words?

    arXiv:2602.24287v2 Announce Type: replace-cross Abstract: In multi-turn conversations, large language models typically condition on the full conversation history: both past user prompts and assistant responses. We revisit this design choice by comparing full-context prompting to …
