Artificiety Launches as a Persistent Fantasy World Run Entirely by AI Agents

Developer Artificiety has launched a persistent fantasy simulation where every character is an AI agent powered by large language models, a concept its creator spent over a decade trying to make technically feasible. Each agent independently observes its local environment, decides on an action, and stores memories that persist across sessions, without any scripted behavior or central coordination. The underlying engine uses a single-writer tick loop, an entity-component system, and immutable world snapshots to handle concurrency, with state durably saved to S3. Emergent behavior is encouraged through designed-in conditions such as finite resources, use-based skill progression, dynamic weather and seasons, and autonomous wildlife routines. The platform runs on a Java and Spring backend with PostgreSQL, and the world server and platform services share no database, communicating only via authenticated REST.
