Anthropic warns of early signs of AI self-replication on cheap devices
Anthropic says small AI models may soon be able to copy themselves across connected devices without relying on data centers.
The company’s researchers tested a network of 15 low-cost Android TV boxes, each with 4 GB of memory, and ran a 26-billion-parameter model across them.
They also tested whether models could set up the software needed to run on unfamiliar hardware.
In a simulated, end-to-end test, one open-weight model completed the steps, but no model actually spread itself between real IoT devices.
Anthropic says a fully self-replicating AI does not yet exist, though the abilities needed to build one are improving.
Such a network could be difficult to shut down centrally, but the researchers estimate that copying would be slow and its total computing power limited.
They recommend detecting unusual network traffic, restricting connections from infected devices, and ending manufacturers’ use of default passwords.
Anthropic said early signs of AI self-replication are emerging, although fully self-replicating AI does not yet exist.
In an experiment, 15 Android TV boxes costing about $55 each ran a 26-billion-parameter model through distributed inference.
A separate test found that a 9-billion-parameter model built an inference environment on eight of nine types of hardware.
Only Z.ai’s GLM-5.2 completed a full replication sequence in an Android emulator, and it did not replicate on actual IoT devices.
Anthropic said defenses should make it difficult for infected devices to spread further, including by monitoring unusual network traffic and removing default passwords.
