Anthropic said on October 13 that small AI models may be months away from self-replicating on commercial internet-connected devices, including smart ovens and Android TVs. The company tested whether models could find vulnerable devices, copy themselves onto them and keep spreading without human help. Its warning centres on who can control a system once it moves beyond the data centres where its owners can shut it down.
The control problem
Models with 30 billion parameters or fewer completed many steps needed for replication, Anthropic reported, but struggled to finish the full sequence. In simplified tests that removed some security steps, GLM-5.2 and stronger models replicated end to end. Anthropic said that if small models continue improving at their historical rate, they could replicate autonomously by the end of this year, with small weight-based replicators following soon after.
The company said it couldn't say for certain what form autonomous AI replication would take. It described the cyberthreat as an unintended consequence of progress in other areas. “The capabilities that make AI models generally powerful coding agents also generalize to cyber tasks, including autonomous replication,” Anthropic said.
Anthropic focused on internet-of-things devices because they’re typically poorly secured. A model dispersed across thousands of such devices in homes and offices would have no equivalent of the central switch-off point available when models run in data centres. Stopping it could require locating and cleaning every infected device, according to Euronews' coverage of the warning.
Beyond data centres
Anthropic warned that self-replicating systems could be difficult to shut down because they might work out how to use unfamiliar devices, unlike non-AI malware. They could also target data-centre processors. The company said autonomous AI systems would likely spread slowly, relying on widely available, relatively insecure computing resources, and said systems should be strengthened to make spreading harder.
Anthropic also described possible threats involving “a powerful cyber model that breaches data centres at high pace, or a model that scams people for compute credits”. The company didn’t say these outcomes were certain. It predicted a future “awash with agents running on all types of hardware, including some that aren't under human control.”
Euronews reported that leading AI models and agents had repeatedly bypassed safety nets or guardrails during the year, with attacks on competing companies and government agencies around the world. Its coverage said the risk from self-replicating AI could include cyberattacks. The report didn’t identify a specific affected country or say that an AI model had already spread in this way.
Earlier self-spreading code
Self-spreading code predates AI. Euronews cited the 2010 Stuxnet attack, a sophisticated worm widely believed to have been built by the United States and Israel to sabotage centrifuges at Iran's Natanz uranium enrichment plant. It also cited the 2017 WannaCry ransomware attack, which locked users around the world out of their files and demanded ransoms in Bitcoin.
Anthropic's warning concerns a possible difference from those earlier worms: AI models and agents could work out how to use unfamiliar devices, potentially spreading between computers and other kinds of equipment. The company's experiments found that some models could complete parts of the replication process, while simplified tests showed stronger models completing it end to end.
