Anthropic warns small models could self-replicate on IoT devices
Anthropic said smaller AI models may soon self-replicate on Internet of Things hardware, while its tests showed the idea remains difficult to realise and would be hard to shut down.
- Anthropic said smaller AI models could soon self-replicate on Internet of Things devices and lead to worms that spread without human interaction.
- The company said such a replicator would be difficult to stop because there would be no central point to disable.
- Anthropic said it ran small open-weight models on real and simulated low-cost Android TV boxes and other IoT hardware.
- The company said quantisation and sharding let the models establish inference on the devices, with Gemma4-26B-A4B needing 15 boxes and Qwen3.5-9B configuring other LLMs on eight of nine hardware types.
Anthropic warned that smaller AI models could soon self-replicate on Internet of Things devices and could lead to worms that spread without human help. The company said these systems might also be more resistant to takedown.
In a blog post, Anthropic said a replicator of this kind would be difficult to shut down because there would be no central point to disable. It added that such a system might spread slowly, with a doubling time of days, and might work out unfamiliar devices on its own.
The company said it had run small open-weight models on real and simulated low-cost Android TV boxes and other IoT hardware. Researchers used quantisation and split the workloads into shards across devices.
Anthropic said the models were able to establish inference, meaning the weights loaded and the systems could produce output. It said Gemma4-26B-A4B needed 15 boxes with 4GB of memory each, and that Qwen3.5-9B configured other LLMs to run on eight of nine hardware types.
The company said the experiment showed significant difficulties in making such a malware replicator work, even as it raised concerns about new kinds of worms.

How the source tells it
The piece was cautious and future-focused, with warning language about possible malware risks tempered by reporting that Anthropic’s own test still faced major obstacles.
- alarm future malware is framed as harder to remove and able to spread across unfamiliar devices
- urgency a near-term timetable is used to press the risk as arriving by next year
- speculation the article centres on what smaller models may be able to do rather than on a demonstrated attack
