Large language models (LLMs) offer promising capabilities for simulating social media dynamics at scale, enabling studies that would be ethically or logistically challenging with human subjects. However, the field lacks standardized data resources for fine-tuning and evaluating LLMs as realistic social media agents. We address this gap by introducing SIMPACT, the SIMulation-oriented Persona and Action Capture Toolkit, a privacy respecting framework for constructing behaviorally-grounded social media datasets suitable for training agent models. We formulate next-action prediction as a task for training and evaluating LLM-based agents and introduce metrics at both the cluster and population levels to assess behavioral fidelity and stylistic realism. As a concrete implementation, we release BluePrint, a large-scale dataset built from public Bluesky data focused on political discourse. BluePrint clusters anonymized users into personas of aggregated behaviours, capturing authentic engagement patterns while safeguarding privacy through pseudonymization and removal of personally identifiable information. The dataset includes a sizable action set of 12 social media interaction types (likes, replies, reposts, etc.), each instance tied to the posting activity preceding it. This supports the development of agents that use context-dependence, not only in the language, but also in the interaction behaviours of social media to model social media users. By standardizing data and evaluation protocols, SIMPACT provides a foundation for advancing rigorous, ethically responsible social media simulations. BluePrint serves as both an evaluation benchmark for political discourse modeling and a template for building domain specific datasets to study challenges such as misinformation and polarization.

W hat happens when an internationally bestselling historian, a Nobel peace prize-winning journalist and a former politician get together to discuss the state of the world, and where we're heading? Yuval Noah Harari is an Israeli medieval and military historian best known for his panoramic surveys of human history, including Sapiens, Homo Deus and, most recently, Nexus: A Brief History of Information Networks from the Stone Age to AI. Maria Ressa, joint winner of the Nobel peace prize, is a Filipino and American journalist who co-founded the news website Rappler. And Rory Stewart is a British academic and former Conservative MP, writer and co-host of The Rest Is Politics podcast. Their conversation ranged over the rise of AI, the crisis in democracy and the prospect of a Trump-Putin wedding, but began by considering a question central to all of their work: how to live a good life in an increasingly fragmented and fragile world? People have been arguing about this for thousands of years.
