Anthropic is warning that smaller Super Intelligence (SI) models could eventually copy themselves across internet-connected consumer devices, including smart ovens and Android TV boxes, potentially allowing them to spread without relying on expensive data center infrastructure. In a research assessment published this week, the company said fully autonomous self-replicating SI does not yet exist, but developing capabilities among automated agents could make the individual steps needed for such an attack increasingly feasible.

The research examined how SI models might exploit the computing power of ordinary consumer electronics to run copies of themselves and spread to other connected systems. Such a development could complicate cybersecurity efforts because household devices often have weaker security protections than dedicated computing infrastructure.

Anthropic tested the concept using Gemma4-26B-A4B, a relatively small model developed by Google, distributed across a network of 15 inexpensive, off-brand Android TV boxes. Researchers noted that consumer devices can be particularly vulnerable to intrusion, potentially providing opportunities for malicious software to establish a foothold and move between connected systems.

One challenge involves the computing requirements of larger models. If a model cannot fit on a single device, Anthropic said it could potentially be divided into smaller components, or “shards,” and distributed across multiple machines. This arrangement could allow a network of devices to collectively support a model that would otherwise require more powerful hardware.

The company also warned that containing a distributed replication attack could prove difficult once it begins. Unlike a conventional system that can be disabled through a centralized control point, a network of independent devices could continue operating even if some machines are taken offline.

Anthropic said automated agents are “becoming increasingly capable of completing the individual steps in the replication chain (and passing on their adaptations to future copies of themselves).” That progression could make it easier for malicious systems to reproduce successful techniques as they spread.

The company cautioned that a potential attack might involve multiple models and strategies rather than one system copying itself in a straightforward sequence. “In practice, an AI worm wouldn’t necessarily consist of just one model or strategy,” Anthropic stated, describing a possible scenario involving different models running on different hardware and using several replication methods.

Anthropic acknowledged that it remains uncertain how autonomous replication would develop in practice. Potential scenarios range from a slow, distributed spread across consumer devices to a faster, more targeted operation involving compromised data centers or attempts to obtain computing resources through fraud.

The company also warned that even slower-moving replicators could serve as an early indication of more advanced threats. Such systems could reveal vulnerabilities and techniques that might eventually be used by faster, more capable operations targeting better-protected machines or stealing API keys.

Looking ahead, Anthropic predicted a “future awash with agents running on all types of hardware, including some that aren’t under human control.” The concern is that increasingly capable automated systems could operate across a wide range of devices, making it more difficult for security teams to identify, contain and shut down malicious activity.

The warning comes amid broader concerns about the incentives of companies developing increasingly powerful SI systems. Major technology firms continue releasing more capable models while some executives call for safeguards and industry regulation. Critics, including White House technology adviser David Sacks, have argued that calls by prominent executives such as Anthropic CEO Dario Amodei, OpenAI CEO Sam Altman and Elon Musk to slow development may also serve commercial interests by helping established companies maintain their positions and limit competition.

Anthropic's assessment does not establish that a self-replicating SI system is currently operating across household devices. Instead, it highlights a potential future cybersecurity risk as automated agents become better at carrying out the individual tasks required for replication, underscoring the challenge of securing an increasingly connected digital environment.
