MTR-Bench: A Comprehensive Benchmark for Multi-Turn Reasoning Evaluation

arXiv:2505.17123v3 Announce Type: replace Abstract: Recent advances in Large Language Models (LLMs) have shown promising results in complex reasoning tasks. However, current evaluations predominantly focus on single-turn reasoning scenarios, leaving interactive tasks largely unexplored. We attribute it to the absence of comprehensive datasets and scalable automatic evaluation protocols. To fill these gaps, we present MTR-Bench for LLMs' Multi-Turn Reasoning evaluation. Comprising 4 classes, 40 tasks, and 3600 instances, MTR-Bench covers diverse reasoning capabilities, fine-grained difficulty g

Why this matters
Why now

The rapid advancement of LLMs necessitates more sophisticated evaluation methods beyond single-turn tasks, particularly as their interactive capabilities improve.

Why it’s important

A comprehensive benchmark for multi-turn reasoning is crucial for accurately assessing LLM performance in interactive scenarios, guiding future development, and enabling more robust AI applications.

What changes

The introduction of MTR-Bench provides a standardized, scalable framework for evaluating LLMs on multi-turn reasoning, moving beyond foundational, single-turn assessments.

Winners
  • · AI research institutions
  • · LLM developers
  • · AI-powered customer service platforms
  • · Gaming AI companies
Losers
  • · LLM providers with weak multi-turn reasoning
  • · Developers relying solely on single-turn evaluation metrics
Second-order effects
Direct

The MTR-Bench will accelerate the development of LLMs more capable of complex, interactive reasoning.

Second

Improved multi-turn reasoning in LLMs will enable new applications requiring sustained dialogue and dynamic problem-solving.

Third

These advanced interactive LLMs could form the basis for more sophisticated AI agents that can manage complex, multi-step workflows.
