Frontier LLMs like GPT-5.4 and Claude Opus 4.7 show significant verbal tics

By PulseAugur Editorial · [1 sources] ·

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.

    The Rise of Verbal Tics in Large Language Models: A Systematic Analysis Across Frontier Models

    arXiv:2604.19139v2 Announce Type: replace Abstract: As Large Language Models (LLMs) continue to evolve through alignment techniques such as Reinforcement Learning from Human Feedback (RLHF) and Constitutional AI, a growing and increasingly conspicuous phenomenon has emerged: the …
