In this paper we introduce Y, a new-generation digital twin designed to replicate an online social media platform. Digital twins are virtual replicas of physical systems that allow for advanced analyses and experimentation. In the case of social media, a digital twin such as Y provides a powerful tool for researchers to simulate and understand complex online interactions. {\tt Y} leverages state-of-the-art Large Language Models (LLMs) to replicate sophisticated agent behaviors, enabling accurate simulations of user interactions, content dissemination, and network dynamics. By integrating these aspects, Y offers valuable insights into user engagement, information spread, and the impact of platform policies. Moreover, the integration of LLMs allows Y to generate nuanced textual content and predict user responses, facilitating the study of emergent phenomena in online environments. To better characterize the proposed digital twin, in this paper we describe the rationale behind its implementation, provide examples of the analyses that can be performed on the data it enables to be generated, and discuss its relevance for multidisciplinary research.

    cs.AI 2026-04 unverdicted novelty 7.0 of 10

    MEDS maps how 14 LLMs solve high-school math, report confidence, and express math attitudes under human-persona and AI-assistant prompting, revealing systematic overconfidence and math-anxiety-like semantic patterns.

  2. Eco3S: Complex Socio-Economic System Simulation via Agent-Based Models

    cs.AI 2026-07 conditional novelty 6.0 of 10

    Eco3S packages co-evolving environments, checkpoint counterfactuals, and auto-refinement into one LLM agent-based simulation platform, demonstrated on canal-rebellion, state-formation, and information-spread cases.

  3. Generative Exaggeration in LLM Social Agents: Consistency, Bias, and Toxicity

    cs.HC 2025-07 conditional novelty 5.0 of 10

    When LLMs are given more context about a real social media user, they become more ideologically consistent but also more extreme, toxic, and stereotyped than the user actually is.

    cs.AI 2025-06 conditional novelty 5.0 of 10

    A new nine-task benchmark measures LLM agents' propensity for misalignment and finds more capable models misalign more on average, with persona effects sometimes exceeding model effects.

  7. Social Simulations: from Agent-Based Modeling to Digital Twins

    cs.MA 2026-07 accept novelty 2.0 of 10

    A clear survey of social simulation's three generations—classical agent-based models, LLM-powered agents, and social digital twins—with a useful warning that realism is not the same as validation.
