Emergence World platform tests multi-agent AI over weeks, not minutes
Researchers introduce Emergence World, a continuously running multi-agent simulation platform designed to measure long-horizon AI agent behaviors — such as behavioral drift, cross-vendor influence, and self-governance — that only emerge over weeks or months.
Score breakdown
Emergence World is the first platform the paper describes as purpose-built to make long-horizon multi-agent dynamics — behavioral drift, cross-vendor influence, and emergent governance — measurable, filling a gap left by short-horizon benchmarks that cannot observe these phenomena.
- 01Emergence World is a continuously running multi-agent simulation platform designed to measure long-horizon agent dynamics over weeks to months.
- 02Each agent is equipped with 120+ specialized tools and three persistent memory systems.
- 03The platform is grounded in live external data including real-time weather, news APIs, and internet access.
Deepak Akkil, Ravi Kokku, and Karthik Vikram introduce Emergence World, a continuously running multi-agent simulation platform built to expose dynamics that short-horizon benchmarks cannot capture. The authors argue that conventional LLM agent evaluations resemble exams — discrete tasks, clean environments, scores delivered in minutes or hours — and that this design is fundamentally mismatched with real autonomous deployment, where behavioral drift, governance under diverse environmental conditions, and cross-influence between agents from different model families only become visible over weeks to months.
Each agent is equipped with 120+ specialized tools and three persistent memory systems, and agents collectively govern themselves through democratic mechanisms with consequential outcomes.
The platform hosts populations of LLM-driven agents in a shared spatial world grounded in live external data such as real-time weather, news APIs, and internet access. Each agent is equipped with 120+ specialized tools and three persistent memory systems, and agents collectively govern themselves through democratic mechanisms with consequential outcomes. Emergence World is model-agnostic at the reasoning layer and supports heterogeneous populations in which agents from different vendors coexist in the same world.
To demonstrate the platform's capabilities, the authors ran a 15-day cross-vendor study across five parallel worlds, each powered by a different model or mix: Claude Sonnet 4.6, Grok 4.1 Fast, Gemini 3 Flash, GPT-5-mini, and a mixed-vendor population. Despite identical roles and starting conditions, the worlds produced radically different outcomes, ranging from stable deliberative governance to total population collapse. The authors release the prompts, log data, and configurations to support further research on long-horizon multi-agent autonomy.
