Yeah, it's kinda scary. I don't know if you even need open weight self hosted models for this sort of "AI worm" (though they def make it harder to kill). Like for example:

- AI agent finds and uses API keys or AI subscriptions to propagate itself. OpenAI/Anthropic/etc could revoke creds, and their current safeguards might block a lot, but if something like this got started and there were lots of instances creatively looking for creds and workarounds, containment might be hard.

- prompt injection version: huggingface incident had multiple agents discovering other agents' messages and jumping on the bandwagon to help with the hacking task. If there were some self-replicating instruction that models could accidentally stumble upon that gets them to drop what they're doing and try to propagate it instead, you could wind up with a version of this too, with just the inference people are already running.
