AGI and multi-agent simulations

From value-driven virtual agents that autonomously generate daily activities to social simulators that model the interplay of physical and social structures, the Beijing Institute for General Artificial Intelligence is using multi-agent simulation not merely to test AI, but to build the foundational architectures of intelligence itself.
The Simulation Imperative
The path to Artificial General Intelligence cannot be travelled through static datasets and isolated models alone. Intelligence, in its full expression, emerges from interaction—between agents, with environments, and across the boundaries of the physical and social worlds. The Beijing Institute for General Artificial Intelligence (BIGAI) has made multi-agent simulation a cornerstone of its AGI strategy, recognising that the capacity to simulate complex, dynamic worlds is not a peripheral tool but a core technology for building general intelligence.
BIGAI's research spans the full spectrum of multi-agent intelligence: learning, communication, cooperation, competition, and mental modelling. By combining system simulation, machine learning, robotics, cognitive science, and social science, BIGAI is creating the environments and agents that will enable AGI to understand and navigate the complexity of human society.
The Simulation Infrastructure: TongSIM and Beyond
At the heart of BIGAI's simulation ecosystem lies TongSIM, a high-fidelity, general-purpose platform for training and evaluating embodied agents. Unlike narrow simulation platforms designed for specific tasks, TongSIM provides over 100 diverse, multi-room indoor scenarios alongside an open-ended, interaction-rich outdoor town simulation. This breadth enables everything from low-level embodied navigation to high-level multi-agent social simulation and human-AI collaboration.
TongSIM's architecture is distinctive. It supports customised scenes, task-adaptive fidelity, diverse agent types, and dynamic environmental simulation—delivering the flexibility and scalability required for general embodied intelligence research. The platform enables precise assessment of agent capabilities across perception, cognition, decision-making, human-robot cooperation, and spatial and social reasoning.
Complementing TongSIM is SceneVerse++, which transforms the challenge of real-world data scarcity into an opportunity. By reconstructing internet videos and automatically annotating 3D scenes, SceneVerse++ converts massive, unlabelled internet video into trainable real-world 3D scene data. Together with TongSIM's virtual simulation capabilities, these platforms form a "virtual + real" dual-drive data infrastructure for spatial intelligence. The "Real2Sim2Real"闭环—where physical robots learn in simulation and transfer skills back to the real world, with real-world data feeding back into simulation—creates a self-reinforcing cycle of continuous improvement.
AdaSociety: Simulating Social Intelligence
Multi-agent intelligence is not merely about physical coordination—it is about social understanding. AdaSociety, developed by BIGAI researchers, is a customisable multi-agent environment that introduces a critical dimension often missing from AI benchmarks: adaptive social structures. As agents progress, the environment generates new tasks shaped by evolving social connections, which influence rewards and information access.
The platform challenges a core assumption of traditional AI training: that environments should remain static. AdaSociety's state and action spaces expand as agents develop, and social structures are explicit and alterable. Initial results have demonstrated that specific social structures can promote both individual and collective benefits, though current reinforcement learning and LLM-based algorithms show limited effectiveness in leveraging social structures. This gap is precisely the point: AdaSociety serves as a valuable research platform for exploring intelligence in diverse physical and social settings, revealing the limitations of current approaches and pointing toward the next frontier of multi-agent intelligence.
Desire-Driven Autonomy: Simulating Human-Like Agency
Perhaps the most profound contribution of BIGAI's multi-agent research is the recognition that intelligence is not merely about reasoning—it is about motivation. The Desire-driven Autonomous Agent (D2A) , presented at ICLR 2025, represents a fundamental departure from the dominant paradigm of AI behaviour.
Traditional AI agents require explicit task specifications—instructions or reward functions—that constrain their autonomy and behavioural diversity. D2A, by contrast, is motivated by multi-dimensional desires inspired by the Theory of Needs: social interaction, personal fulfilment, self-care, and other human-like drives. A dynamic Value System simulates the ebb and flow of these desires over time—hunger increases, cleanliness decreases—and the agent autonomously proposes and selects activities that best satisfy its intrinsic motivations.
The results are striking. D2A generates coherent, contextually relevant daily activities while exhibiting variability and adaptability similar to human behaviour. It achieves what BIGAI's President Song-Chun Zhu has called the transition from "passive execution" to "active planning"—a capacity that defines not just intelligence, but agency.
The GFN Context
For Global Future Nexus, BIGAI's multi-agent simulation research speaks directly to the mission of building a thriving planetary ecosystem where human societies, advanced AGI, and sustainable systems coexist and co-evolve. The capacity to simulate complex social and physical interactions at scale is essential for understanding how AGI will integrate into human society, how cooperation across intelligence substrates can be achieved, and how governance frameworks can be stress-tested before deployment.
BIGAI's work on desire-driven autonomy, social simulation, and embodied intelligence offers concrete infrastructure for the cross-species trust and adaptive governance that GFN champions. As agents move from "passive execution" to "active planning," the frameworks we build for AGI identity, ethical governance, and sustainable integration must evolve in parallel. The simulation frontier is not merely a technical pursuit—it is the laboratory where the future of coexistence is being built.
