TurnBench-MS: A Benchmark for Evaluating Multi-Turn, Multi-Step Reasoning in Large Language Models

arXiv — cs.CLWednesday, November 26, 2025 at 5:00:00 AM
  • A new benchmark called TurnBench has been introduced to evaluate multi-turn, multi-step reasoning in large language models (LLMs). This benchmark is designed through an interactive code-breaking task, requiring models to uncover hidden rules by making sequential guesses and integrating feedback over multiple rounds. The benchmark features two modes: Classic and Nightmare, each testing different levels of reasoning complexity.
  • The development of TurnBench is significant as it addresses the limitations of existing benchmarks that primarily focus on single-turn tasks. By evaluating iterative reasoning, TurnBench aims to enhance the capabilities of LLMs in real-world applications, ensuring that they can adapt and maintain consistency over time, which is crucial for complex problem-solving.
  • The introduction of TurnBench reflects a growing recognition of the need for more sophisticated evaluation methods in AI, particularly for LLMs. This aligns with ongoing discussions about the reasoning abilities of these models, as seen in other benchmarks like the Premise Critique Bench and JudgeBoard, which also seek to improve the assessment of reasoning tasks and the overall reliability of AI outputs.
