Anthropic has published research claiming that self-replicating AI worms could be only months away from spreading across vulnerable Io T devices. The frontier lab's report, released Monday, suggests AI models could eventually replicate without relying on datacenter hardware. A 9-billion-parameter model successfully set up inference on eight of the nine hardware types Anthropic tested, and a distributed Gemma4-26B-A4B instance ran across 15 generic Android set-top boxes at 0.39 tokens per second. Anthropic said a replicator like this would be hard to shut down because there is no centralized point to switch off.
For the replication step, the researchers used Z.ai's GLM 5.2 to propagate a copy of Llama3.1-8B across eight Google Cloud instances running an Android 15 emulator. The model spread to all eight nodes in four of five trials and seven of eight in the other. Anthropic said this suggests future small models could complete the replication process as well.
However, the study has clear limits. Anthropic largely ignored the cyber exploit element, relying on earlier papers, and the target nodes were custom-built and deliberately left open to attack. The company itself described its exploitation tests as providing "an upper bound on real-world success." Common botnet entry points are also preventable with basic security hygiene.
Speed is another caveat. Anthropic estimates such worms might take days to double in size, while Mirai doubled in roughly an hour when it appeared in 2016. The report is a useful warning about future risks, but it does not show that such a worm is already spreading or imminent.
