A batch of inexpensive TV boxes can not only run the AI model but also display its answers. Experiments regarding autonomous AI replication indicate that small models may eventually spread without the need for data center access, through devices such as smart ovens and Android TV boxes, forming a distributed “worm” without a central point of shutdown.

Key Points

• A 9B model established reasoning capabilities on eight out of nine types of test hardware.
• GLM-5.2 completed a simplified replication process in an experimental network.
• Distributed model weights enable low-memory devices to jointly support larger models.

In a research blog written by Anthropic and Daniel Freeman, these experiments are described. The authors believe that small models may be just a few months away from achieving the required capabilities; based on current trends, this capability threshold is expected to appear around the end of 2026. They used a general ability index as a rough proxy to estimate this.

Stranger IoT Autonomy on hardware AI Replication

Small models are already capable of completing most of the work required to establish inference on unfamiliar machines – that is, the process of running the model. Qwen3.5-9B has successfully run on eight out of nine types of hardware, with test environments including Jetson Nano, Mac computers, and RTX 4090.

Researchers used Memento, which is a tool framework built on top of the Pi encoding proxy.

Models with parameters not exceeding 30B have completed many individual replication tasks, but combining these tasks into a successful and complete process remains more challenging. Models like GLM-5.2 and even more powerful ones have completed simplified end-to-end evaluations.

AI How Worms Copy Themselves Between Devices with Limited Memory

A weight-based replicator will run the model directly on the compromised hardware. When a device runs out of memory, the model weights can be split into multiple shards and distributed among machines that communicate with each other.

During the demonstration, Gemma4-26B-A4B was run on 15 Android TV boxes, each costing approximately $55 and equipped with 4GB of memory. The pipeline parallelized the allocation of certain layers of the model to each box, achieving a speed of 0.39 token per second.

The replication evaluation used eight GCP nodes, which ran Android 15 simulators. The proxy found the target, accessed the unauthenticated ADB port, transmitted the payload, and established a Llama3.1-8B inference. The worm model itself ran on a separate inference server. GLM-5.2 reached all eight nodes in four out of five trials, and in another trial, it reached seven nodes.

For Qwen3.5-9B running on TV box hardware, the estimated setup time is between 28 and 51 hours, supporting a rough replication interval of about one to two days. Gemma4-26B-A4B on the other hand, requires 71 to 150 hours. The author describes this type of propagation as slow but sustained.

Adaptability distinguishes the AI worm from traditional botnets.

AI Worms can pass on prompts, code, and failure records to subsequent instances, allowing strategies to be continued across generations. Researchers tested this inheritance by having Qwen3.5-9B repeatedly attempt to establish reasoning.

Unlike hardcoded botnets targeting specific devices, the proxies under test are capable of establishing connections across different families of hardware. According to Synthient, Kimwolf has infected over 2 million devices, mainly Android TV boxes; the author estimates that a group of devices of similar size could support approximately 133,000 copies of Gemma4-26B-A4B.

Small models are still weaker in the field of social engineering. Adding suggestions from Opus version 4.8 to Qwen3.5-9B did not result in any measurable improvements in reasoning capabilities.

Cyber defense focuses on the traffic related to dissemination and payload delivery.

Weights transmission at multiple GB levels, continuous inter-device inference traffic, and network scanning can all become signals for ISP monitoring.
