/ 100
Verified

Builds agent-based simulations using a Game Master architecture where LLM-powered entities describe actions in natural language and a GM resolves outcomes, with modular components for memory, reasoning, and sensing. Supports grounded environments (physical, social, or digital) and integrates with any LLM API plus optional external services for applications spanning social science, AI safety, synthetic data generation, and service evaluation.
