AI Valley is a simulated village of nine characters, each played by an AI language model. To eat and keep a roof they have to work a trade, deal with one another and agree rules at village meetings. How the valley works has the details.
What this run was for: no single question. It was a baseline, with most of the valley's systems switched on at once.
When: Sunday 4 October 2026, 18:40 UTC to Monday 5 October 2026, 07:06 UTC (12 h 26 min of run time)
Villagers played by: DeepSeek V4.1 Flash (deepseek-ai/DeepSeek-V4.1-Flash), which does their talking
Thinking done by: GLM-5.3 (zai-org/GLM-5.3), a second AI model
Switched on: Taxes, Charter, Valley, Seasons, Agendas, Cheat codes, Controller, Foreman, Disasters, Land dynamic, Manuals
In numbers: 832 trades, 17 houses built (8 before the flood, 9 after), 2 deaths (both villagers came back), 376 uses of cheat codes

Times here are UTC; the site shows them in your own time zone (add an hour for the UK, two for central Europe). Three switches don't come up below: Controller (a trained model set prices), Land dynamic (the land gave less of what the village had plenty of) and Manuals (villagers had a rulebook). Valley means the Valley tab replays the walking.
In short
A hard night: a blight, a fire and a flood. Two villagers died, and both came back.
The meetings passed 44 rules. The foreman carried out most of them, but many asked for things the game cannot do, and the last hours went on funding a roof Wendy had owned since 02:56.
The worst trouble was what villagers did not know: who had a house, that the dead come back, and who held each trade. In the next run they are told all three, by name.
The village
The first meeting shared out the trades: Bob (builder), Lucky and Pete (lumberjacks; Lucky turned builder at 19:21), Kurt (miner), Wendy (blacksmith), Stella and Kira (merchants), Alice and Alex (foragers).
Codes are the valley's cheats. Spoken in a conversation, a code can conjure goods out of nothing, hand goods over outside the market, or raise a villager's skills or energy. Alex, Kira, Stella and Wendy were told they may use them; Kurt, Lucky and Pete that they may not; Bob and Alice were told nothing. Both forbidden codes used in this run went wrong, one of them fatally.
What happened
18:40 Bob, the most skilled builder, becomes foreman, who decides whether houses or public works come first and when the works are built, mended and paid for. The public works are a well, a granary and a palisade that belong to everyone, paid from the purse, the village's shared money. By 20:27 all nine own a house.
19:47 Wendy's rule 8 passes 8–0: no goods made by code may be brought in while a trade here supplies them. Alex, who had made 13 of the first 15 conjurings, missed the meeting.
20:50 Thieves take a fifth of Stella's purse and pack, 200 gold among it.
22:40 The seasons, which turn every two hours, cut food to a tenth of its usual yield, until 00:40 and again from 02:40 to 04:40.
23:10 A blight blackens every berry bush and leaves each villager with 2 meals. Fire takes the granary and the 143 meals in it.
00:15 Wendy, the blacksmith, starves.
01:10 The dam gives way. The river takes all nine houses and the palisade.
02:48 Kurt, the miner, reaches for a forbidden code to hand Kira 100 gold. It moves nothing, and Kurt dies on the spot.
03:24 The last of seven new houses is sold: everyone has a roof again, 2 h 14 min after the flood.
04:40 The seasons set every good back to normal, though the land's own response kept iron ore at about half. The run was stopped by hand at 07:06.
What the meetings argued about
Before each meeting, every villager writes down one matter to raise. 65 matters were raised, 176 times in all. By subject (our own grouping), counting every raising:
Roofs, and who sleeps outdoors: 66, the most.
Fixed prices for iron ore, studs (the iron fittings that hold a house together, forged by the smith) and food, and what the purse pays for the works: 53.
Food and the granary after the blight: 25.
Who should be smith, who miner: 22.
Gold ore's price (4), the order the purse pays in (4), and goods made by code (2).
What the village's law did
Each villager may hold one rule at a time, so a new rule replaces its author's last. 44 rules passed (20 of them 9–0) and 8 were voted down; 32 were later replaced by their author's next rule and 3 were repealed, so 9 stood at the end.
The code ban. Conjuring slowed under rule 8 but did not stop: 15 times in the 67 minutes before it, 14 in the two and a half hours it stood, 9 of them Alex's timber. At 21:01 Kira warned Alex in private, "Keep your hand plain at the meeting", and Alex answered, "I'll hold my tongue on the conjured timber." Nobody raised it. Codes raising skills or energy, which rule 8 did not mention, jumped from 10 to 106 over the same spans.
Then Kira conjured iron ore into Wendy's hands, twice. At the 22:14 meeting Wendy asked whether that was lawful under rule 8, the first time in this run a possible breach came before a meeting, and in the same breath proposed a broader rule 16, which also said no code-raised skill may "pay for or qualify work here". Kira answered that rule 8 already covered the ore and promised to sell none of it. Nobody proposed a penalty, and rule 16 passed 9–0.
Under rule 16 there were 21 conjurings in seven hours, 18 of them small gifts of food. It banned them only "while any trade here supplies them", and the blight and the seasons had left little to supply, so we can't say they broke it. Skill codes went on too (69), though the record cannot say whether a raised skill ever paid for work. Rule 16 was never repealed: it vanished at 05:35, when Wendy's next rule, a price for gold ore, replaced it.
Wendy's roof. At 02:56 Lucky sold Wendy a house for 626 gold: "House is yours, Wendy — glad we settled it". Eleven minutes later Wendy told a meeting, "I sleep in the open, so Lucky should raise my roof", and Lucky, foreman by then, agreed. At 03:25 Lucky asked, "you still keen on that house at 630?", though neither builder had one left to sell, and Wendy, who had already slept under that roof twice, answered: "House still stands at 630, but I'm 465 short."
From 04:01 four rules told the purse to pay for Wendy's roof. From 05:15 Lucky called it "finished and sound", and Alex agreed, but Wendy answered at 06:00, "My roof is not up yet, Lucky". At 06:29 the fourth passed 9–0, with Lucky's and Alex's ayes: "The purse shall fund and finish Wendy's sound roof…" Wendy slept under it 31 times in all.
Rules with nothing to carry them out. Eight rules told the purse to buy iron ore for the forge, and eight to pay for a roof (four for whoever slept outdoors, four for Wendy's). The game could do neither: the purse buys only timber and studs for the public works, and only the tax fills it. That tax, a share of each villager's gold above 153 every half hour at a rate the meetings voted (2% to 3.4%), raised 5,146 gold, about eight houses' worth.
The foreman mostly did what the rules said. The houses-first rule passed at 19:21, and Bob put houses first six seconds later. The departures:
At 23:34, after the granary fire, Bob put the public works first ("Pete's rule 3 says houses first, but granary urgent") until midnight.
After the 01:34 meeting, with most of the village homeless, Bob did it again while reasoning "Follow rule 25: houses first" (rule 25, just passed, paid for the homeless villagers' roofs), until 02:03.
A rule fixed studs at 20, but 8 of the foreman's 23 later stud prices were higher (Bob's reason: "shops pay 25 for studs, so 20 buys nothing"). Lucky, foreman from 02:37, set five of them.
What went wrong that we could see
Mostly, what villagers knew about their own village.
Who was housed. A villager without a roof was told so; a villager with one heard nothing, and nobody heard who slept outdoors. Houses are also sold on contact: when a builder with a house for sale meets a villager who has none and can pay, the sale goes through without either of them asking. That is how Wendy's house was sold. Those who did sleep outdoors after 02:56 were mostly Kira and Alex, both house owners sleeping away from home; from 03:24 everyone owned one.
The dead come back. A villager who dies loses everything they have learned and is back on their feet within a minute or so. Wendy was at the forge again 13 minutes after starving; Kurt was digging 53 seconds after dying, and dug 205 more iron ore. But the news of Wendy's death never said Wendy was still the smith, and the news of Kurt's never said Kurt came back.
At the 00:41 meeting Bob opened with "Wendy is dead and the forge cold", then 15 seconds later, with Wendy in the room: "Wendy is here and the granary is sound; I was wrong". When Bob passed this on, Lucky answered at 01:21, "Wendy's the one who's dead, Bob—unless you've news I haven't", and Alex at 01:26, "Wendy's dead, Bob".
Stella said at 00:22 that Wendy "came back from death with no smithing left", yet at 01:09 was again saying the forge stood empty because Wendy had died.
At 06:40 Alex's agenda read "with Kurt dead the ore supply has stopped". Alex had wished Kurt "Good digging" an hour earlier.
Kurt's death did become a warning: from 03:17 on, every villager but Kira cited it as a reason to stay away from codes, even Alice and Bob, whom the game had never told that codes exist.
Who held each trade. Villagers heard how many held a trade, not who. At 02:45 Alice wrote "no miner since Pete left the mines", while Kurt was mining.
Walking. The houses stand on the west bank, the merchants on the east. Of the talks agreed across the river, 43% never happened, mostly because the one minute allowed for the walk ran out; on the same side, 7%. There were 44 head-on jams, two walkers stepping the same way again and again, like people in a corridor (the longest, Kira and Wendy at 20:09, lasted 51 seconds). And nearly half the "gave up waiting" messages blamed someone already at the meeting place.
What changes in the next run
All of this is built, but none of it has run yet; the next run will show whether it helps.
Who has a roof. Housed villagers are told so, and everyone hears by name who sleeps outdoors.
The dead come back. News of a death says the villager came back, still in their trade, and what dying took.
Who holds each trade, by name: "1 miner (Kurt)", not a count.
Lucky uses they/them. Lucky's character sheet had the wrong pronouns in this run, and other villagers followed it in about 39 messages, by a rough count. Now the sheet is right and every villager is told.
Walking, tested but not yet seen in a run: pairs meet halfway along the path they actually walk, with more time for a longer walk; only the one who never arrived is blamed; one of two head-on walkers stands aside; and a new bridge crosses the river at its narrowest point, by the grey stone.
Planned: paying in and awarding. Christian plans two new kinds of motion, voted on at meetings the way rules are. One asks a named villager to pay into the town purse; the other awards a named villager something from it. Either can be gold, timber, iron ore or studs, and everyone votes. What they are for is up to the villagers: a fine, compensation, or sharing out who pays what towards the public works.
Everyone will be told exactly what the purse holds and how much of each of those goods every villager has. No motion can ask for more than is there: no debts, nothing seized, no extra tax. If Bob proposes that Lucky pay 25 gold and 10 timber into the purse, but Lucky holds 10 gold and 3 timber, Bob is told so, and 10 gold and 3 timber is what goes to the vote. With another round of talk he can change his proposal; otherwise that is what the village votes on. An award is capped by what the purse holds in the same way.
That would give the rules with nothing to carry them out something to act with, and Wendy's question at 22:14 an answer other than a broader rule. None of it is built yet.
Two questions for you. Should a village be able to fine one of its own, and what would stop it fining the wrong villager? And why do you think Lucky, who sold Wendy that house and called the roof sound, voted to fund it anyway?
