An experiment with TypeSafe's Jev

24 people. One flood. Jev chooses.

I gave 24 simulated people a town. Then I flooded it. Each person has their own memories, relationships and limited sight. Jev chooses whether they escape, help someone or look for family.

1:32 · 1080p · Edited replay of real Jev API inputs and outputs

One private world per person.

Each character gets a separate request containing only their own observations, memory and available actions. Jev returns a typed choice and option probabilities. The game executes movement, helping and the consequences of the flood.

The close-ups show actual decisions and measured request timings. The wider shots follow the rising water, collapsed bridge and people reaching high ground. Request animations are reconstructed for the edit; the character inputs and responses come from the recorded run.
