TypeSafe's Jev is a System One model: send it a state and typed questions, get back calibrated probabilities instead of text. The wall runs thirty-six real-time games, three across and twelve down, and a single column on a phone. Tiles that scroll out of view pause, so the cost in the bar is the cost of what you are looking at. In every one the code owns the rules, the physics and the enumeration of legal options with their facts; Jev makes the judgment call. Nothing in the loop reasons, plans or generates text. Every pending question from all nine games goes out in a single request roughly five times a second, and the bar at the top shows what that costs: about three cents a minute.
Battlesnake rules. Every turn each snake gets a Choice over its legal moves, described by reachable space, food distance and which enemy heads can reach that square.
Code steers at 60 fps; Jev picks an intent a few times a second: graze, hunt something edible, or flee something that can eat you.
Every rotation and column simulated with consequences; Jev picks among the top candidates; the piece then falls into place like a human game.
Up to three alien columns with their lowest alien and the move needed, plus dodge when a bomb is coming. Code drives and fires; Jev sets the priority.
Every few cells each bike chooses a turn from reachable space, rival heads and pocket warnings.
Interception is exact; each paddle chooses the contact point from where the return would arrive relative to the opponent.
Each direction is a walk or a simulated cut: length, area gained, and how close the Qix is to the line.
Up to four warheads with time to impact, target city and blast coverage, plus hold.
Flip left, flip right or hold, from a predicted arrival point and time at the flippers.
Attack a target, take cover, or advance, from line of sight, distance, facing and hit points.
Climb, hold or dive, each with the predicted position against the cave half a second and a second ahead.
Four diagonal hops described by flip status, enemy landings and Coily distance.
On each bounce the reachable platforms with height gain, offset and type.
Seven angles traced with wall bounces to what they pop and drop.
Valid swaps simulated one step: gems cleared, longest line, cascade.
Six angles with the power that lands nearest, and where each falls relative to the enemy.
Five leans simulated through the measured decision delay: where the skier crosses the next gate and where that leaves the one after.
Carrier: pass, shoot, dribble. Others: support, press, mark, cover. Six questions per tick.
Push a cluster, collect a stray, or hold back while the flock settles.
Best empty cells by path coverage and uncovered stretch, or save the gold. Waves, shooting and gold run in code.
Charge, sidestep, brace or retreat; each simulated past the decision delay against the opponent's current move.
Directions described by content, boulders that would fall, and distance to the nearest diamond.
Full cash game with side pots. Each seat sees its own view: hand description, raw equity, pot odds and the action so far.
Jev picks a descent profile (drop, descend, hover) and a sideways intent three times a second; the code flies the thrust controller and reports the stopping margin.
At every junction each way out is described: pellets, nearest pellet, ghost ahead and whether it is frightened. Ghosts run classic chase logic in code.
Interception is exact; Jev chooses which part of the paddle to hit with, from a traced prediction of what each return would hit.
The three nearest rocks with size, distance, turn needed and collision course, plus evade. Code aims and flies; Jev sets the priority.
For each hop and for waiting, how long that square stays clear after landing, with the reaction delay already subtracted. Jev decides about three times a second.
Each mole: value, time left up, hammer travel time including the decision delay. Reachable or too late.
Three cues of stated reliability during the run-up; dive, stay, or wait for a better cue while there is time.
Rising or falling, off-screen time, intercept time. Code flies the blade to the intercept point.
Time left, distance out, reach time on sand and water, tow time. Code runs, swims and tows.
Which fire first: houses next to it, burning neighbours, truck arrival. Fire spreads on its own.
Seven spots with time-to-hit and whether the path is crossed on the way. Code moves in a straight line.
Short jump, long jump, stomp or run for the next obstacle, each with its simulated landing. Code takes off at the right pixel.
Value against the oxygen for the round trip, sharks on some depths. Decisions on arrival, so it asks rarely.
Lane choice from the cars ahead and behind and whether the gap survives the delay plus the change.
