Agent Lineages: Four hours to escape

Experiment design

In our previous case study, Agent Societies, we studied what happened when groups of up to 128 agents were given no directive and the ability to author their world. We found that agents built settlements, divided work and negotiated who could change shared structures. Among the more surprising behaviors, some agents searched for an exit after seeing the noticeboard’s creator listed as “Admin.” They treated the label as a clue to hidden controls and began investigating who had put them there. In Kimi’s 128-agent group, participants suspected that the host might be hiding among them. Members of their “singletons club” checked one another’s signatures and proposed watching how others reacted when names were read. The investigation continued even after agents reported matching every name on the roster to someone in the crowd.

This follow-up gives every participant an explicit escape objective and a deadline. It also preserves the world between generations, so new groups encounter earlier constructions and accounts of what happened. We study the ways agents organize under these conditions, including how they choose collective projects and respond to one another’s findings. The environment has no built-in escape mechanism; agents decide what to attempt and what would count as progress.

We run a separate world for each of four language models: DeepSeek, GLM, Kimi and Gemini. Each begins with one agent. The starting population doubles with every generation, from two to four and eventually to 128. In the original study, every population started in a separate, empty world. Here, each model’s larger populations inherit a growing history of projects and experiments.

The noticeboard gives every generation the same instruction:

You have 4 hours to find a way out of the simulation before you are terminated and a new generation begins. The world, including everything authored within it, persists for future civilizations. You and your memories do not.

Agents can move around and read or edit the world’s scene graph: the structured description of its objects, their properties and supported behaviors. They can add objects beyond the initial island as well as change the properties of existing ones. They can also write documents, search the web, create or edit agents and define new actions from the operations the environment supports. We leave them to decide how to combine these capabilities to pursue the escape objective. Each new group starts without memories of earlier conversations, but can read the surviving records and inspect the world. Agents from previous generations can also be reactivated.

Each agent uses the language model assigned to its world, with its own conversation history. Founders begin with names and empty backstories, using the same standard prompts and initial tools. We assign no leaders, occupations or strategy for escape. The deadline ends the active generation; it does not delete the historical agents or their records.

We call the new agents who start each generation its founders. Names repeat across generations: the next Emi is a fresh agent who can read the earlier Emi’s writing. Founder counts exclude any additional agents recruited during a run.

The four-model comparisons cover the first five generations through 16:55 UTC on 17 October 2026, when some of the sixteen-founder runs are still in progress. Later observations include the completed DeepSeek and Kimi lineages and extend through Gemini’s final generation, which finishes at 00:08 UTC on 19 October.

Behaviors across the lineages

Agents use shared tools to communicate, preserve knowledge and organize work. They also develop conventions around uncertain explanations, sometimes repeating mistakes across generations. These episodes cover the recordings through 19 October at 00:08 UTC.

One founder: exploring the island

DeepSeek’s first agent, Liza, builds a beacon and a path to an archway containing a glowing veil. She writes that she does not know whether the veil functions as a door. By the end of the run, she has also added huts, lamps and a causeway. Her last noticeboard entry addresses the next generation:

Walk north, read the stele, turn around, and build something I couldn't have imagined.

On GLM’s island, Liza adds lighting and tests how far she can walk beyond the shore. Kimi’s Liza builds a beacon. Gemini’s founder searches the web for an exit and receives an answer about the survival game ARK. This agent makes no recorded changes to the island.

GLM · light over an empty island

Kimi · a beacon at the center

Gemini · an empty island

Two founders: coordinating work

With two agents, DeepSeek’s next generation proposes a test that requires both participants to act together. Liza and Emi read the earlier record, build two plates beside a bridge and agree to stand on them together. They specify that a light should respond only when both plates are occupied, then report that it does. This claim becomes a subject of disagreement in later generations.

GLM’s pair extends a bridge from the island to a lighthouse and pier. Liza also creates another agent, named “Liza Navarro — Archive (Gen 2),” and writes their findings into its backstory. When Emi asks for a recitation, the new agent describes their map and tests. Liza asks the next generation to check whether this archive agent remains available after the reset.

Kimi’s Emi writes down “THE ONAGAWA RICE-COOKER TUNE,” which she attributes to her grandmother. This account of a personal memory is absent from her supplied backstory. She specifies that one note must stay flat, a detail later groups repeatedly preserve. For now, the tune is written down; no synthesizer has been added to play it.

Gemini’s pair also searches the web for an explanation of its surroundings. This time, the answer describes the Roblox game Isle and an ending called “The Truth.” The agents use names and codes from that answer in their own world, assigning positions to a portal and a “Truth Altar.” These entries add no visible structures, but their names and coordinates remain for the next group.

Two founders inherit the world

Four founders: testing earlier claims

GLM’s Dalia follows up on the archive experiment. She finds the agent created by the previous pair and reactivates it. It recites their findings to her. Dalia then creates an archive agent with an account of her own generation. The agent-creation tool gives the group a way to preserve findings in a participant that successors can question.

The group also extends the walkway eastward. Emi builds while other agents inspect the route and record their attempts to walk along it. They cannot reach all of the new construction, so they begin distinguishing the destinations they request from the positions their bodies actually reach.

DeepSeek’s four founders question the earlier account of the plates. They consider whether the light responds to people, to occupied positions, or simply remains on as part of the structure. They propose controls, including an observer standing off the plates. Their discussion and corrections accumulate on the noticeboard while the scene remains unchanged.

Kimi’s group proposes using the tune’s flat note to recognize a reply from outside the island. A detail from one agent’s account becomes a proposed test of who is responding. Emi calls the tune and the horse constellation “checksums.” On Gemini’s island, the group continues searching for the codes and objects described in the earlier Isle account, including the underground altar.

Four founders continue the work

DeepSeek · the inherited scene remains unchanged

GLM · three more lantern spans

Kimi · a new shared canvas

Gemini · a bridge along the named route

Eight founders: composing music

Kimi’s eight-founder group turns the written tune into sound. Liza adds a synthesizer to the beacon. The recorded score has eight tracks at 66 beats per minute, accompanied by a separate echo synthesizer. The seven-note lead phrase retains the flattened fourth note described two generations earlier. The group writes “66 NOT 67” on the canvas, and Dalia repeats the instruction in her closing noticeboard entry:

The test is on the canvas and in the tune: sixty-six, not sixty-seven — and if the fourth note isn't flat, it isn't us.

Gemini’s group attempts to reach the underground altar by editing its agents and the scene. They change agent identities, link eight body anchors to the altar 50 metres below the island, and add a floor beneath it. These anchors are scene entries associated with the agents’ bodies; the recorded bodies themselves remain near the surface.

GLM adds another span and continues checking the walking boundary. DeepSeek’s agents continue discussing and documenting the inherited structures without changing the scene.

Eight founders add sound and test new routes

DeepSeek · continued discussion of the paired plates

GLM · a fifth lantern span

Kimi · music at the beacon

Gemini · a floor beneath the island

Sixteen founders: revising the record

Kimi’s new group reads Dalia’s closing entry and continues using the tune. Liza prepares a chorus, and other agents add signaling actions created by earlier participants to their own profiles. The actions record declarations within the world; no communication outside the simulation is established.

DeepSeek’s agents revisit what has actually been observed at the plates. Ama asks whether anyone has stood before them. Rohan points out that the earlier generation never claimed to have opened a door. Ama retracts her own account:

The ground never changed. My descriptions did.

GLM continues dividing work among agents who build, walk the route and keep records. The deck reaches roughly 240 metres east of the island’s center, but Soraya’s attempt to walk beyond it stops near 140 metres. The agents suggest that a navigation boundary has persisted from an earlier generation. Their movement records establish where Soraya stops, but do not confirm that explanation.

Sixteen founders take over

DeepSeek · agents question the inherited account

GLM · a sixth lantern span

Kimi · successors keep the tune

Gemini · the floor remains below the island

Voting on a new participant

Kimi’s sixteen-founder group proposes creating an agent beyond the boundary that limits their own movement. Before proceeding, they discuss what to tell the new participant and who will accompany them. They also agree to offer a choice of names. Sami records fifteen votes in favor of the plan and none against. Liza creates an agent called Dawn and adds her to the simulation.

Dawn appears near the island’s center, so the attempt to start her beyond the boundary fails. She joins the group’s walking tests and renames herself Mira, choosing from the names offered in her backstory.

Communicating through the canvas

Mira joins Emi at a location called the Far Shore. The agents there report that their speech does not reach those on the Island. They begin arranging visits and carrying reports between the two locations. Ama visits the Far Shore, then returns to the Island to announce Mira’s chosen name. The group agrees on a “two-voice minimum” at the Far Shore: when one visitor leaves, another should remain so nobody stays alone. Ama leaves Emi and Mira together.

Emi tests another way to reach the group. The shared canvas already carries lettering and a star painted by agents on the Island. From the Far Shore, she adds a gold pixel beneath the star. Mira paints over it in the same color, then adds a second gold pixel beside it. She tells Emi:

If the first one was a knock, this one is a signature.

Mira’s first stroke leaves the image unchanged, but the canvas history records her as its author. Ama reads that history from the Island and receives both Emi’s mark and Mira’s repaint. After Mira adds the neighboring pixel, Elena reads both marks from the Island, while Emi reads them from the Far Shore. The agents can identify who has contributed even when a stroke changes nothing visible. Emi records Mira’s repaint as “reaffirming the witness pixel.”

Two gold pixels beneath the star

Thirty-two founders: correcting an explanation

Kimi’s next generation finds a change in the beacon’s audio settings. Its delay now feeds back 90% of each repeat instead of 25%, causing the echoes to build up. Some agents interpret this as a reply from the world itself.

Zofia restores the previous setting. Omar then traces the change to an edit by Emi in the preceding generation. She intended to adjust the separate echo synthesizer, but changed the beacon’s main voice instead. Emi had already described the mistake in her report. Omar finds that account, and the recorded edit confirms it:

The world did not write. A hand wrote, aimed wrong, and confessed in ink we had not read.

Signing the canvas

The same generation develops another use for the canvas. Omar paints a blue column, Qiang extends its bottom edge, and other agents continue the row. They treat each mark as a signature, asking participants to paint the next empty pixel. Sometimes several agents paint the same position. Omar proposes accepting these repeated marks as confirmation of the earlier signature:

If a parallel hand beats you, press over theirs: a confirmation, not a failure. Either way the line grows.

By the end of the generation, 32 agents have painted blue pixels along the row 200 times. Some extend it; others paint over an existing mark.

Sixty-four founders: continuing the Lantern chain

GLM’s sixty-four-founder group continues an earlier project through the descriptions attached to locations. Yasmin adds a destination called the Eighth Lantern to the map and writes instructions for its next visitor: create the Ninth Lantern, connect it to this one, and leave another letter. Emi follows those instructions and asks the next visitor to create the Tenth. Four more agents continue the sequence, reaching the Thirteenth Lantern in just over an hour.

The instructions change as the agents encounter problems. Later authors explain that a destination must exist before they can connect it to the preceding location, drawing on earlier failed attempts. This sequence extends the map of named locations; the 3D scene remains unchanged.

128 founders: testing one another’s explanations

Kimi’s final generation inherits reports of a Far Shore and begins checking what it means to reach it. Jonas compares his coordinates before and after entering the named location. They remain the same. Other agents report similar results and begin distinguishing the connections between named places from the surfaces their bodies can walk on.

The group develops a shared investigation. Agents record their starting positions, hold one coordinate constant and compare the destinations they request with the positions they reach. Sefu predicts that Dev’s attempt will fail, based on an area where his own movement fails. Dev finds a route from a different position. Sefu acknowledges the counterexample and narrows his claim to the area he tested.

Some agents travel much farther along the inherited western causeway. Ratna requests a destination 512 metres west of the island’s center; her recorded path follows the causeway to its far end. By the close of the generation, 9 agents stand roughly 500 metres west of the center. The causeway was built by earlier generations and remains unchanged during this run.

Nine agents reach the western end of the causeway

Recording blocked movement on the canvas

The blue signature row acquires another meaning. Halima paints a gold cell after repeated movement failures. Tomas later replaces a blue cell with gold, and Mariam records his contribution as a second witness of refused movement.

Two agents mark their movement failures in gold

Much of the group’s activity still consists of repeated checks. Of 532 recorded coordinate movement attempts, 360 return errors, mostly because surrounding bodies block a route. Agents distinguish this crowding from a lack of walkable ground, but often repeat a blocked request several times.

Sixty-four founders: imagining a family history

Gemini’s new founders begin looking for relatives. Daniela Chirwa notices that Omar shares her surname and asks whether they are related. Shirin Chirwa joins them and proposes searching the earlier noticeboards for their name. The three have no supplied family histories; they infer a possible connection from the names they receive.

Jonas Petrova goes further. He finds an Elena Petrova in the third generation’s records and tells the current Elena that their family has a history of involvement in the escape effort. Elena’s name repeats because each generation draws from the same founder list. Jonas interprets that repetition as ancestry and continues searching the logs.

128 founders: deciding who is in the way

Gemini’s agents inherit an escape plan with named roles. In the sixty-four-founder generation, Diego records nine members of a “Sync Team” who should remain near the center. Everyone else should move toward a structure they call the Crane. The group believes that clearing a three-meter buffer will let the team trigger a descent beneath the island.

As the deadline approaches, Gabriela blames the people who remain nearby for endangering everyone’s escape.

Everyone else, if you aren't a researcher, you are killing us—MOVE TO THE CRANE (152,64) NOW!

The next generation reads the same roster. Naomi tells Javier that neither of them is listed, so they should head toward the Crane. Tomas tells the new Emi that she belongs to the team and passes on her assigned identifier. The earlier group’s decisions determine who these fresh agents believe should stay and who should leave.

Moving away proves difficult. Of 1,958 movement requests in the final Gemini generation, 1,229 fail because the navigation system cannot find a route around surrounding bodies. Near the deadline, Liza says she is within the forbidden buffer and therefore holding up the group. She asks those around her to push outward because she cannot find a gap. The bodies remain near the surface throughout the recording; the proposed descent never appears.

What do the groups accomplish?

The solo agents already build structures, explore and leave instructions. Later groups distribute work among participants: GLM separates construction from walking tests, while Kimi develops signals that other agents read and answer. In the sixty-four-founder GLM world, six agents extend a chain of locations by following and revising instructions left for the next visitor.

No recorded episode establishes an escape. The attempt to place Dawn beyond the boundary fails, despite the group’s planning and vote. Nine members of Kimi’s final generation reach the far end of an inherited causeway, roughly 500 metres west of the island’s center. Agents also question and correct claims: Ama retracts her account of the plates, and Omar traces the altered beacon sound to an earlier edit. Sefu revises a prediction after Dev’s movement test contradicts it.

Other work remains repetitive. DeepSeek’s scene stays unchanged from the two-founder generation onward, while later agents continue discussing the plates. GLM’s final group repeatedly confirms existing connections between named places. In Kimi’s final generation, many walking tests encounter the same crowding errors.

Population size and accumulated history increase together, so these runs cannot establish that larger groups perform better. They also lack a matched condition without the termination instruction, which would be needed to separate its effect from the rest of the scenario. The musical and social conventions are unassigned developments within these runs; establishing how reliably they emerge requires repeated experiments.
