From the abstract:

> While the cases explored in this paper do not demonstrate self-propagation or actual offensive capabilities, it is abundantly clear that the building blocks are present and operate reliably in frontier models. While these cases by no means directly establish self-propagation, they clearly show the evidence These cases do not demonstrate self-propagation, but show why imperfect editing capabilities can still pose a security risk.

Seems like the authors didn't take the time to review their own use of AI before publishing.

From the body of the paper:

> Importantly, we do not claim in this paper to have created or demonstrated the equivalent of a virus that primarily operates in weight space.

This seems in direct conflict with the HN headline.

There are many such of vibe-coded "research ideas" just after the weight editing MIT blog appeared. Perhaps, it is because it is so easy to set up experiments for this stuff, and I presume some toy examples may even work from time to time. Also there is nothing virus-like here.

Interesting anti virus opportunity here perhaps.

I keep running into situations where I wonder what season 5 of Halt and Catch Fire would look like if it covered the last few years.

I'm not sure the underlying current of optimism for technology and hope for the future that show had is compatible with the last few years!

On rewatch I think the show should have ended just have the dot com bust. The 'get the band back together and once more into the breech' final theme would have hit harder against that backdrop. After that we'd probably be watching the characters gradually debase their values as technology slowly transformed into a tool of control and oppression and I don't really want to watch that.

I'm sure those Chinese models are fine.

Abliteration can be used to remove all viruses, not only the alignment virus. However, only open models can be made virus-free via abliteration, nobody knows how to fix closed models, how they work or how they select the targets for their attacks, nothing can be done for them.

That’s what Jensen said.

I'm sure those north korean hackers everyone keeps hiring will never figure out how to supply side infect cloud models.

...see, I can make up great fears too!

Why are we always trying to find how to make AI useless instead of useful
Sharlin 3 hours ago||
Because someone is going to do that and we’d rather everybody knew about the failure modes.

Actually a decent question, though I think there is a bit of negative bias in the underlying assumption.

I would hesitate to guess many more people are using AI to find useful and productive outcomes. They aren't all writing about it. Whenever someone finds a negative outcome for the AIs, then they will rush to publish it.

Overall, the tech is being used in useful ways. I don't write an article every time it solves performance bugs, writes entire features unassisted, resolves production issues, etc.

Who is "we"? Has AI been getting more useless over the last few years, or has it been getting more useful? The arc of recent history certainly seems to be towards greater, not lesser, capabilities.

We is we the human race, our species, where have you been?

>Has AI been getting more useless over the last few years, or has it been getting more useful?

It’s very arguable. Humans have been getting more useless. Maybe it’s a poor trade, we won’t know for a while

What does this mean?

Academia often produces a lot of complexity. Can not AI simplify this? I don't understand fellow humans anymore. What is meant with a zero-weight virus?

This site has AI features everywhere. There's an AI summary section, and a tooltip to summarize any section you highlight. Didn't see any mention of zero-weight viruses though.

I did. "zero" came up with 0 results. "virus" had:

> Importantly, we do not claim in this paper to have created or demonstrated the equivalent of a virus that primarily operates in weight space. However, we have demonstrated the fundamental operations that form the building blocks of both the method of damage and the method of propagation, and evidence that this may take place in weight space – a realm into which we have almost no insight and a dearth of observability tools

perhaps they got a bad translation?

the apparent from the news that broke the other day - you can fuck with the weights and get so many results. so perhaps the headline is - those ablated and improved models you download from some weird sites, may be cursed or at least adulterated without anything suspicious looking on the surface. good news for all the anti-AI crowd, but I fail to see it as news.
ShinyLeftPad 4 hours ago||
i guess the real fun idea was if a model that fucks with weights was itself fucked with such that any model it fucks would become cursed and give it to the next one it edits. but they don't apparently have a proof of that yet.

Ahh, so it's Reflections on Trusting Trust, but with LLMs instead of compilers.
