## Summary  
The paper investigates how large language models (LLMs) cope when a user’s intent changes during an ongoing conversation, revealing that today’s static‑setting evaluations cannot capture this dynamic behavior. By converting single‑turn benchmarks into multi‑turn dialogues where the user gradually reveals, revises, or redirects their goal, the authors demonstrate a persistent performance gap across model families. Their work shows that strong results in fixed settings do not translate to evolving‑intent scenarios, exposing a fundamental limitation of current LLM capabilities.

## Key Contributions  
- Finding 1: Static‑setting performance does not transfer to the evolving‑intent setting, indicating a lack of continuity between evaluation and real interaction.  
- Finding 2: Substantial drops (roughly 30–50 %) are observed across multiple task domains and model families when intent is altered mid‑conversation.  
- Finding 3: The gap stems from LLMs lacking mechanisms to track and act on shifting user intent, a problem invisible to static benchmarks.

## Methodology  
The authors transformed existing single‑turn tasks into dynamic multi‑turn conversations that preserve the original evaluation protocol. Instead of creating new annotations, they reused established benchmarks as controlled testbeds, allowing each task’s original metric to be applied while simulating an evolving user intent through incremental disclosures and revisions.

## Results  
Across several representative tasks—such as planning a trip, summarizing documents, and generating code—the models performed well when the user’s goal remained constant. However, once the goal was revised or redirected during later turns, performance declined sharply, especially for smaller or less‑fine‑tuned LLMs that rely on short‑term memory. The degradation varied by model family: base models suffered larger drops than those fine‑tuned with instruction data.

## Significance  
This research highlights a critical gap between how LLMs are evaluated and how they actually behave in collaborative settings where users continuously reshape their goals. Until this capability is addressed, future agents may appear competent only under static constraints, misleading stakeholders about their true adaptability.
