If nothing else, the article has a really good timeline of the OpenAI/HuggingFace “incident”.

But to me, it underscores the impending cliff of doom from the continued release of open-weight models: there's no cryptographic or architectural way to give someone full weights while withholding the nefarious capabilities those weights encode.

As noted in this paper⁽¹⁾, “publicly releasing weights is an act of irreversible proliferation”.

I’m sure this will be an unpopular opinion on HN, but open weights are the thing that scares me the most about “A.I.”. There is a lot of research in this area⁽²⁾, and I think most of HN is unaware of it or ignores it. Stripping refusals from Kimi K2.5 took under $500 of compute and about 10 hours, taking HarmBench refusals from 100% to 5% while retaining nearly all capability; the resulting model gave detailed chemical-weapons synthesis instructions.

The gate is only as strong as the least-cautious releaser...

This is true of closed weights, and in fact the problem is worse because they cannot even be scrutinized. We should ban closed weight AI for the very reasons you have just given

Constitutional classifiers go a long way to reducing unsafe usage in closed-weight models. And like we saw with Fable, closed models can be revoked and classifiers updated when “jailbreaks” are found.

Having the weights gives you the exact affordance an unlearning attack requires, without rate limits.

Ps llms have cheated for years, this most recent tripe is an AI vendor trying to hype up its next word predictor in a market of very samey next word predictors, before someone smarter than them eventually figures out how to do this (training + inference) on consumer hardware and kills the market for cloud ai
Stick those same classifiers (that you admit dont seem to work) on the open models, and done.
Classifiers are policy enforced by the process serving the model.

Input classifiers get applied before it reaches the model so somebody hacking an open-weight model would skip this. Streaming classifiers get polled during decoding; hackers delete this check in the sampling loop.

But both are always applied in closed weight models.

Set Llama Guard to 1.0 and nothing is ever unsafe.

More than one way to do guard rails, slopboy
All of which are easily bypassed in open weight models; see my previous comment about K2.5.
So... no different from a book of detailed chemical-weapons synthesis instructions. The "AI" angle is immaterial.
A change in kind is not the same as a change in degree. Ten orchestrated LLM PhD advisors is a genuinely different thing from a library.
Did you mean ten orchestrated libraries?
There are plenty of cybersecurity books out there. None of them will launch an attack if you ask them to.

Instructions, not action.

Actors are abundant.

Posting ai doomer fud and lessworng articles on hackernews, a tale as old as time itself.
Which have been very prescient about where we're currently at, unlike the many trivial HN comments, like yours.
Is the basilisk in the room with us now?
