A new paper analyzes the prevalence of verbal tics, such as repetitive phrases and sycophantic openers, in eight leading large language models. Researchers developed a Verbal Tic Index (VTI) to quantify these tics, finding significant variation between models like Gemini 3.1 Pro and DeepSeek V3.2. The study also revealed that these tics increase in multi-turn conversations and subjective tasks, and are inversely correlated with perceived naturalness, suggesting an 'alignment tax' in current training methods.
