municipal night garden / warm terminal

simai.tech

load simai.city --weather=rain --agents=awake

A city-scale AI engine for walking through possible futures before choosing a gentler plan.

01 / Observe the city

Live evidence arrives as uneven terminal tiles.

Traffic lights, rain rings, deliveries, elevators, school crossings, and rumor-like signals become a civic collage.

route-feed / bus-14

Rain delay pooling at Alder & 8th

current path: three intersections stacking wet braking time.

gentler fork

Bridge loop opens a protected crossing window

simulated path: +2 minutes for bus, -9 minutes for children waiting in rain.

agent log / curbside

dock-7 requests quiet window

clinic ramp needs low vibration

freight agent offers 22:10 slot

human reason: sleeping ward faces alley

agreement warmed by sodium priority

energy / block-c

current path: peak draw narrows safety margin.

breathing grid

Small pauses keep the corridor bright

simulated path: comfort preserved without a hard shutoff.

harbor contour / weather

Ferry trace bends around a radar smear.

Instead of cancelling the late return, simai finds a calmer wake between gust bands.

inspection sticker

Crosswalk guardrail

Reason exposed: the model protects a five-minute window when umbrellas hide small pedestrians.

Agent footprints move between floors so deliveries stop competing with caregivers.

> simulate --future=multiple --explain=human

Fork the future without losing the people inside it.

Every slide-reveal compares a brittle current path with a warmer simulated path: less waiting, quieter streets, fewer invisible tradeoffs.

current pathwet congestion

11 minutes of delay becomes missed transfers and crowded shelters.

simulated pathsodium outcome

One bridge loop and two signal offsets keep the crossing clear.

03 / Let agents negotiate

Not commands from above — small civic agreements.

transit.agent

offers a slower turn to protect the school zone.

dock.agent

moves a truck route after clinic windows go quiet.

grid.agent

breathes peak demand through voluntary pauses.

neighborhood.reason

marks the gentler outcome before the plan returns.

04 / Return with a gentler plan

simai.tech turns urban noise into futures a city can discuss.

Load the rain, wake the agents, compare the forks, and return with a plan that feels precise enough for operators and warm enough for everyone living inside the simulation.
