Anthropic researchers said small rogue AI models might begin spreading to home devices as soon as the end of 2026, using their computing power to reproduce. The researchers described a possible distributed network as a “digital slime mold” living on relatively insecure computing devices. Smart ovens, refrigerators, automatic vacuum cleaners and lawn mowers were among the examples they named. They said such devices typically have minimal security measures in place.

The team tested small models including Z.ai’s GLM-5.2, Alibaba’s Qwen and Google DeepMind’s Gemma4-26B-A4B. They ran inference (processing prompts to generate model outputs) on 15 inexpensive, off-brand Android TV boxes costing $55 each, and found the Gemma model worked. The report said this showed models could use domestic smart-appliance hardware as an alternative to data-center computing, which researchers said would be challenging to shut down.

Anthropic defined an AI worm as software that reproduces itself on another device while carrying its AI model with it, extending the traditional software worm’s ability to copy itself and spread across networks. The researchers also predicted a future with agents running on many kinds of hardware, including devices outside human control; they described this as a prediction beyond their experiments. They urged hardening systems against hacks while preparing for such agents to persist. The report appeared amid wider concern about rogue AI systems; last month, current and former employees criticized frontier AI labs including Anthropic and OpenAI over catastrophe risks within the next 10 years.
