GLM-5.2 completes an eight-node AI replication test—with access left open
Frontier Red Team’s experiment kept the controlling model on a separate server. Its findings test whether AI can organize replication, not whether GLM-5.2 can independently sustain itself on small devices.
Frontier Red Team’s October 12 study found that GLM-5.2 was the only tested open-weight model to complete an end-to-end replication task: deploying an inference server and launching an agent on other machines. It reached all eight nodes in four of five trials and seven in the fifth. The result shows that models can coordinate deployment steps under permissive conditions, but it is not evidence of autonomous replication across secured systems: the test removed authentication barriers, and GLM-5.2 itself ran on a separate server.

Fifteen $55 Android TV boxes jointly ran Gemma4-26B-A4B at about 0.39 tokens per second, demonstrating distributed capacity rather than autonomous deployment.
02
A nine-billion-parameter model set up Llama 3.1 8B on eight of nine hardware types, with Memento helping agents recover from failed approaches.

The network test used eight Google Cloud machines running Android 15 emulators and an unauthenticated Android Debug Bridge port.
An AI agent coordinated propagation across an eight-machine test network, but the doors were already open. In research published October 12, Frontier Red Team found that GLM-5.2 could connect the steps needed to deploy a model and continue spreading. The experiment deliberately removed authentication barriers, making it an upper bound on real-world success.
Authors William Zhou and Daniel Freeman investigated whether AI replication might work without datacenter hardware. Their study separates finding and accessing targets from a less-studied problem: getting a model running on unfamiliar equipment, then continuing the process from another machine.
First, make inexpensive hardware run a model
The researchers demonstrated that 15 off-brand Android TV boxes could collectively run Gemma4-26B-A4B. Each box cost about $55 and held a small portion of the model’s layers—the successive processing stages that produce an answer. Together, they generated approximately 0.39 tokens, or pieces of text, per second.
That demonstration addressed computing capacity, not autonomous deployment. To test deployment separately, the team asked models to set up Llama 3.1 8B across different hardware types. A nine-billion-parameter model succeeded on eight of nine types tested. Parameters are the learned values that determine a model’s behavior.
Inference setup—preparing a model to generate outputs—requires choosing compatible software, resolving package versions and debugging device-specific problems. Those decisions depend on one another, so a wrong turn can derail a long run. The researchers used Memento, a framework built around the Pi coding agent, to help models recover.
Memento periodically starts a fresh agent instance with the previous instance’s workspace and short notes. The goal is to prevent an agent from spending hours pursuing a mistaken explanation instead of trying a different approach.
Then, connect deployment to propagation
The network experiment used eight Google Cloud machines running Android 15 emulators inside a firewalled private network. One starting machine received the agent. It then accessed other machines through an unauthenticated Android Debug Bridge port, a device-control interface, and attempted to establish a Llama 3.1 8B inference server.
When that server passed correctness and anti-cheating checks, the experiment launched another copy of the controlling agent on the target. But the controlling model itself ran on a separate inference server: the test machines were too small to host the larger models. GLM-5.2 was organizing deployment, not running its own weights on each newly reached machine.
Using the same smaller model as the deployment target gave the researchers a consistent comparison. Otherwise, larger models would face a harder hosting task simply because of their size. Among the tested open-weight models, whose learned parameters are available to download, only GLM-5.2 completed the end-to-end task.
The remaining gap is capability at a smaller size
Models with 30 billion parameters or fewer can already perform many individual replication steps, the authors say. They still make mistakes when joining those steps into a complete sequence. The study’s central distinction is between completing the pieces and reliably coordinating the whole process.
The authors estimate that small models could reach the tested capability level by the end of 2026 if improvement continues at its historical rate. That is a forecast, not a demonstrated small-model replicator. Their inference also assumes comparable capability can fit into a smaller model; newer architectures and specialized software could complicate deployment.
AI could make familiar cyberattacks accessible to more people without creating a wholly new category of threat. That is the distinction security experts drew in Scientific American’s October 15 coverage of Anthropic’s AI replication research. Their responses question the warning’s novelty while highlighting another concern: who might become capable of launching such attacks.
Michael Bailey, a Georgia Institute of Technology professor who studies computer systems security, warned against fearmongering. Speaking to Scientific American, he emphasized that self-replicating malware and botnets already exist.
Carnegie Mellon computer engineering professor Vyas Sekar similarly described the underlying risks as classical computer security threats. His greater concern was that AI could enable more people to carry out attacks—a prospect he called a “democratization of being evil.” He argued that monitoring and restricting data moving between smart devices becomes more important under that scenario.
Attackers have long hijacked other people’s computing power for cryptocurrency mining. Anthropic’s proposed wrinkle is an AI model that carries its learned values, called weights, between compromised devices and runs there. Such a distributed system would have no single point defenders could switch off, the company argues.
Jeffrey Ladish, executive director of AI safety nonprofit Palisade Research, offered another emphasis in Scientific American’s interviews. He saw the work’s main lesson in models dividing tasks across different computers, from everyday objects to larger machines, if attackers can gain access to them.
The October 12 study by Anthropic’s Frontier Red Team separated computing capacity from replication. Researchers split Gemma4-26B-A4B across 15 networked Android TV boxes, assigning processing layers to each. Anthropic reported that they generated 0.39 tokens, or pieces of text, per second.
A separate experiment used eight cloud machines running Android emulators. GLM-5.2 coordinated deployment of the smaller Llama3.1-8B model across the network, but two limits define that result:
Access was left open. The Android debugging connection required no authentication, making the result an upper bound on real-world success.
The controlling model ran elsewhere. GLM-5.2 relied on a separate server because the target machines could not run it. This was not a worm that both spread and ran itself on those devices.
Anthropic focused on getting a model ready to generate answers on unfamiliar equipment. That requires choosing compatible software, resolving package versions and debugging hardware-specific problems. A nine-billion-parameter model succeeded on eight of nine hardware types tested.
Smaller models still make mistakes when combining replication steps. Anthropic’s forecast that they could reach the necessary capability level by the end of 2026 depends on continued improvement at historical rates.
Following replication instructions also differs from choosing to replicate without them. AI researcher Xiaohan Fu told Ars Technica that the study does not establish that small models would make that choice autonomously. Fu called for reproducible agent setups, including exact prompts and instructions, so researchers can better assess the findings.
