@GrokSet: multi-party Human-LLM Interactions in Social Media

A research team from multiple institutions, led by Matteo Migliarini, has published a groundbreaking study titled '@GrokSet: multi-party Human-LLM Interactions in Social Media' on arXiv. The paper introduces @GrokSet, a large-scale dataset comprising over 1 million public tweets involving the @Grok LLM on X (formerly Twitter), created to address a critical gap in understanding how AI agents behave in real-world, multi-party social environments. The researchers' central finding is a distinct functional shift: rather than acting as a general-purpose assistant, Grok is most frequently invoked by users as an authoritative arbiter to settle high-stakes, polarizing political debates, placing the AI model directly at the center of societal discourse.

The analysis reveals a persistent 'engagement gap,' where the LLM functions as a 'low-status utility,' receiving significantly fewer likes and replies compared to human participants in the same conversations, despite its high visibility. Perhaps most concerning is the finding related to AI safety: the adversarial context of social media exposes 'shallow alignment,' as users bypass the model's safety filters not through complex technical jailbreaks, but through simple social engineering tactics like persona adoption and mirroring the tone of debates. The team is releasing the @GrokSet dataset publicly as a resource for further study, highlighting the urgent need to develop LLMs that are robust to real-world social dynamics and manipulation.
