Anthropic warns small AI models may soon self-replicate across IoT devices
Anthropic says models of 30B parameters or fewer could replicate on devices like cheap Android TV boxes by year's end, though current tests relied on larger orchestrating models and an exposed debug interface.

In context
- Anthropic says small models may be months from self-replicating on commercial IoT devices; a 9B model got inference running on 8 of 9 hardware types tested.
- Gemma4-26B-A4B ran across 15 Android TV boxes (about $55 each, 4GB memory each) at 0.39 tokens per second.
- Anthropic estimates full inference setup takes 71 to 150 hours for Gemma4-26B-A4B and 29 to 51 hours for Qwen3.5-9B, per Ars Technica.
- GLM-5.2 and stronger models can do end-to-end replication in simplified tests; Anthropic expects small models to match that if they keep improving at their historical rate.
- Caveats per Ars Technica: targets had an unauthenticated Android Debug Bridge exposed, and GLM-5.2 orchestrated the process while targets ran a smaller Llama model.
Why it matters
Anthropic notes earlier work showed AI agents can scan networks, exploit machines and copy model weights across GPU clusters, while IoT worms like Mirai have long targeted poorly defended devices. The report adds that weights could become part of a worm's payload, with no central point to shut down. It lands amid a broader debate over open-weight models, which MIT Technology Review says Anthropic has also cited in warning about GLM-5.3 as a cyberattack risk.
