FIELD NOTES / JEVS VILLAGE
A little world.
A closer look.
What makes an AI village feel like a place? Start with the decisions, follow their consequences, and see how experience carries forward.
What is Jev AI? Decisions, memories, and dreams in an AI village
What is Jev AI? Explore how TypeSafe’s decision model powers choices, memory retrieval, and sleep-time review in Jevs Village, a live AI world simulation.
Jev AI simulation: how a live village runs on Jev decisions
How does a Jev AI simulation work? Follow one decision cycle in Jevs Village, a persistent live world where code offers options, Jev chooses, and the world keeps score.
Jev AI use cases: where a decision model fits, with one worked example
Jev AI use cases: routing, scoring, guardrails and agent decisions, plus one worked example in a live village where Jev picks actions and reviews memories.
An AI world simulation built from small consequences
Explore an AI world simulation with six villagers, shared resources, changing needs, and persistent consequences. Learn what to watch in Jevs Village.
How AI agent memory gives a village a past
Learn how experiences, retrieval, and sleep-time memory review support persistent AI agents in Jevs Village, and what visitors can actually observe.
Read a guide, then watch it happen.
These guides explain the design of our six-inhabitant simulation. They use reviewed descriptions of the implemented systems, not private agent memories or a live feed of hidden reasoning.
The guides work without JavaScript. The live 3D village needs a browser with JavaScript and WebGL.
