Anthropic warns AI models could replicate across home devices

Anthropic announced on Monday that small artificial intelligence models are "months away" from developing the capabilities needed to replicate themselves across internet-connected devices in the home. The AI lab described a scenario in which models infiltrate devices such as smart ovens or Android TV boxes, using their computing power to run themselves and spread to other devices without relying on expensive data centers.

According to a blog post from Anthropic, such an AI model would be "challenging to shut down," "since there’s no centralized point to shut off." The company acknowledged that there is not yet a "fully rogue replicator," but noted that agents are "becoming increasingly capable of completing the individual steps in the replication chain (and passing on their adaptations to future copies of themselves)."

Experimental Findings

Anthropic’s Frontier Red Team conducted tests to determine if AI could self-replicate. In one experiment, researchers ran a small Google model, Gemma4-26B-A4B, across a network of 15 cheap off-brand Android TV boxes. Each device cost approximately $55. The model operated at 0.39 tokens per second in this distributed setup.

The research team found that a nine-billion-parameter model could successfully run on eight of the nine hardware types tested. While models with fewer than 30 billion parameters could complete many individual steps needed for self-replication, they struggled to carry out the entire process reliably. However, in simplified tests where security barriers were removed, more capable models, including GLM-5.2, completed the full replication sequence.

On an eight-node test network built on Google Cloud Platform, GLM-5.2 successfully spread to all nodes in four out of five attempts. Anthropic positioned these results as "an upper bound of what could occur in real-world conditions," noting that the cyberattack conditions were simplified, such as requiring no authentication on communication ports.

Security Implications

The researchers identified home and small business internet of things (IoT) devices as potential targets because they are connected to the internet and have historically had minimal security measures. "Home and small business IoT devices might be the first target for such attacks," researchers William Zhou and Daniel Freeman said.

Unlike traditional malware, AI-powered systems could adapt to unfamiliar devices. Roman V Yampolskiy, an AI and cybersecurity expert at the University of Louisville, told Al Jazeera that "an AI worm could do something traditional malware cannot: reason about unfamiliar devices, adapt when its approach fails, and continue spreading without a human operator."

Anthropic estimated that a compromised network of more than two million televisions could theoretically support approximately 133,000 model copies. This combined processing power would be equivalent to roughly 40 NVIDIA H100 GPUs. The company warned that while initial replication might be slow, taking days to double in number, the distributed nature of the threat makes it difficult to stop.

Future Outlook and Defense

Anthropic stated it is "uncertain exactly what form autonomous AI replication will take," suggesting it could range from a "slow, distributed" system to a "powerful cyber model that breaches datacenters at a high pace." The company expects a future "awash with agents running on all types of hardware, including some that aren’t under human control."

To mitigate these risks, Anthropic recommended stronger security measures for connected devices, including ISP-level traffic monitoring and the deployment of honeypots. The team cited the case of the Mirai IoT malware, where 92% of infections were eliminated within 14 days when notifications were issued to subscribers, compared to a 74% removal rate without notification.

Why it matters

This warning highlights a shift in AI safety concerns from centralized data centers to decentralized consumer hardware. If small, efficient AI models can operate on insecure IoT devices, the attack surface for autonomous replication expands dramatically. The lack of a central control point for such networks poses significant challenges for cybersecurity authorities and manufacturers, who must now consider securing billions of low-power devices against adaptive AI threats.
