Operation-Guided Progressive Human-to-AI Text Transformation Benchmark for Multi-Granularity AI-Text Detection
Researchers introduce OpAI-Bench, a comprehensive benchmark for detecting AI-generated text in progressive human-AI co-edited documents across multiple granularities. The study reveals that AI-text detectability follows non-monotonic patterns, with mixed-authorship intermediate versions often harder to detect than purely human or heavily AI-edited documents, challenging assumptions in existing detection methods.
