Researchers have developed DSIPA, a new framework designed to detect text generated by large language models without requiring model parameters or extensive labeled datasets. The method analyzes sentiment distribution stability, observing that LLM outputs tend to be more emotionally consistent than human writing. DSIPA operates in a zero-shot, black-box manner and has demonstrated significant improvements in detection accuracy across various domains and models, including GPT-5.2 and Claude-3. AI
