Stop Listening to Me! How Multi-turn Conversations Can Degrade LLM Reliability

arXiv:2603.11394v3 Announce Type: replace-cross Abstract: Large language models (LLMs) excel on static benchmarks, but their performance across multi-turn conversations, which better reflect real-world usage, remains understudied. Addressing this gap is critical in high-stakes settings like healthcare, where patients and clinicians are turning to LLM chatbots to address their medical inquiries. Here, we introduce the "stick-or-switch" (SoS) framework, which partitions a question-answer space into multiple sequential presentations to model two safety-centric behaviors: conviction (i.e., stickin

Why this matters
Why now

As LLMs become more integrated into real-world applications, particularly in sensitive areas, the limitations of their performance in sustained interactions are becoming increasingly apparent and critical to address.

Why it’s important

This research highlights a significant reliability gap in current LLM capabilities, especially in multi-turn conversations, directly impacting their trustworthiness and applicability in high-stakes domains like healthcare.

What changes

The understanding of LLM reliability shifts from static benchmark performance to dynamic conversational fluency, requiring new evaluation frameworks and development priorities for robust AI agent behavior.

Winners
  • · AI safety researchers
  • · LLM developers focused on robustness
  • · Healthcare technology providers integrating LLMs
  • · High-stakes application developers
Losers
  • · LLM providers with only benchmark-optimized models
  • · Applications relying on naive LLM conversational capabilities
  • · Uncritically deployed LLM-based solutions
Second-order effects
Direct

Increased focus on conversational reliability and safety frameworks for LLMs.

Second

Demand for new LLM architectures or fine-tuning methods specifically designed for multi-turn conversational stability and consistency.

Third

Regulatory bodies may begin to impose specific reliability standards for LLMs used in sensitive real-world applications.
