A new arXiv paper titled "When Summaries Distort Decisions: Information Fidelity in LLM-Compressed Financial Analysis" explores how large language models (LLMs) can alter financial decision-making when compressing information. The research highlights that LLM-generated summaries, while appearing fluent and factually plausible, can lead to different investment judgments compared to the original source material. The paper identifies two key issues: decontextualization, where evidence is presented without necessary qualifiers, and model dependency, where different LLM compressors yield varied results. To address this, the authors propose "Agentic Context Compression," a method that generates multiple summaries and analyzes their disagreements to maintain decision-relevant context. AI
IMPACT LLM-generated financial summaries may require new evaluation metrics beyond factuality to ensure decision fidelity.
