ReasonOps: Operator Segmentation for LLM Reasoning Traces
arXiv preprint · 2026
ReasonOps is an annotation-free method that segments chain-of-thought traces into 7 recurring reasoning operators—discourse-level moves such as backtracking, inferring, and hypothesizing—that generalize across model families and benchmarks, enabling model identification, correctness estimation, and early quality assessment before a trace completes.
