Pirate Face Rescues LLM Models from Deletion(pirateface.co)

Speaking to the "uncensored model" angle: there's little reason to distribute abliterated weights anyway. Instead of orthogonalising the weights that write back to the residual stream, you can just orthogonalise the activations themselves. It's equivalent.

Orthogonalising activations at runtime is computationally cheap. Just distribute the refusal vectors (few thousand floats per layer), then run against the stock weights. Antirez's DS4 already supports this: https://github.com/antirez/ds4/blob/8db1d1d155cb0400a86a86b9...

Abliterated weights are just a bad habit we've gotten into. It's also deeply suboptimal from a precision point of view to take a model that's already been QATed and distributed in pre-quantised form (DeepSeek V4, Kimi K2.5 or K3...), modify its weights, and re-quantise it. Similarly, abliterated models regain some of their refusal behaviour when they're re-quantised after abliteration -- avoidable by keeping the two separate.

I believe abliterated models are mostly still created at this point because they're "universal": they can not only be run locally, and on cloud GPUs, but also on "managed inference" providers (i.e. services where you hand them a model URI, and they blindly fetch it, load it, and give you inference access to it through standard text/chat-completion APIs. Think HuggingFace Spaces, or Google CoLab, or CloudFlare Workers AI.)

Such managed inference providers have (for now) plausible deniability of behaving ethically (at least enough that they don't get boycotted / scare away investors) due to them being "blind" to what gets run on their systems. They're acting as the inference equivalent of data transit carriers.

But I don't think it would be possible for managed inference providers to publicly expose "runtime activation steering" in the way antirez's DS4 does, without that reading much more explicitly as them inviting unethical workloads.

(Yes, there are other things you can do with runtime steering. But almost all of those things are workload-specific, relying on you privately tuning to the needs of your own dataset. And if you can do that, you can run inference without the help of a managed inference provider. The only time a customer will come along with a pre-made runtime-steering vector file in hand, is if that vector is an alignment-orthogonalization vector.)

Yeah I use a custom fork of llama.cpp that has an abliteration feature that basically does this. It's sloppily vibe coded and I don't have time to coordinate on a way to do this cleanly upstream, but it's absolutely possible and saves a lot of time and bandwidth from being wasted

Interesting. Is there a paper that explains this in a bit more detail, like [0] for abliteration (underlying the Heretic software, afaik)?

That paper you linked has all of the information you need. The linear algebra they do on the weights there to null out one direction reduces to a single (dot-product + broadcast-multiply + add) on the activations.

I didn’t know about that method, thank you. I’ve needed a local model for security research but Qwen 27b abliterated did 30% worse than the stock weights on my internal benchmarks (I just skip the public benches now, it’s honestly useless noise on an operational level).

This is the original description of abliteration and it's quite approachable and interesting to read: Refusal in Language Models Is Mediated by a Single Direction (https://arxiv.org/abs/2406.11717). Warning: changes to your world view caused by seeing "HarmBench" used to maximise expected harm instead of minimising it may be irreversible.

There's an empirical observation that models often have a single direction in their activation space for "hmm no I shouldn't do this". It forms naturally during pre-training, and is then surfaced during post-training to make the model refuse to engage in certain behaviour.

With a little bit of linear algebra you can zap that direction from the model's activations, and it stops refusing to do things. You can also do the opposite: magnify that direction, and the model refuses to do anything at all.

I'm pretty sure this was achieved with prompting rather than with weights, but there is a chatbot available that tries to maximize the motivated refusals:

Damn what's happened since this? Presumably they scramble refusal intentionally somehow now? Like intentionally couple it to "directions" that effect performance if messed with? Or is it more like just don't rely on the model to refuse and instead capture bad responses between generation and delivery?
wren6991 3 hours ago|||
I've seen attempts to obfuscate the refusal direction, like here: https://arxiv.org/html/2608.18093v1

Also this one was interesting, training the model to give preambles with reasons for the reasons for refusal seems to make it less sensitive to modulating the single refusal direction: https://arxiv.org/html/2505.19056v1

My empirical observation is that when a new model is released on HuggingFace, an abliterated version with < 10/100 refusals (baseline usually 100/100) is uploaded the same day, so either these techniques don't work very well or the open-weight labs aren't applying them.

There's some defense-in-depth, like a lot of the "guardrails" people hit on cloud models are classifiers applied to prompt or output, not a refusal generated by the model. Also closed-weight models obviously try to avoid this by not letting you see or modify the weights.

I'm not active in this space but why do you think anything happened since this? As far as I know, it still works.

Instead of editing the weights so they don't create the refusal signal, just let them do whatever, then delete the refusal signal itself. You don't want to edit quantised weights because it causes a loss of precision that can be pretty bad.

So... distribute a LoRA (or equivalent) that modifies the base weights with the abliteration vectors. That makes sense as it would be possible to try different abliterations and keep the storage space down.

Every change to the source is effectively a new torrent. This creates a ton of fragmentation as data is reorganized, remixed, reencoded, and so on.

You can see this with many Linux distros: there is no single Debian torrent that people seed for years because there's always a refreshed version.

Distros are a bad use case for P2P anyway since you depend on upstream as soon as you start upgrading and installing packages.

The problems begin with taking 5-10 minutes to locate a file on the network. That's right, when you ask for a file it takes 5-10 minutes. Also if the file isn't in the network at all then it never terminates.

Nobody noticed because everyone just used the central web gateway that cached every file anyone ever accessed.

You can trivially have storage deduplication for the files served via torrent, transparent to the protocol. The most trivial version of this that you can do today with pretty much any client is having a single directory containing files serving multiple overlapping torrents.

This is true for any distribution method not just p2p. You can even download a nightly through torrents so what does it matter how the data is transferred if it’s always going to require `apt update`?

Well, for a torrent to stay healthy, users have to seed after download, so it can't possibly have the same UX as a standard browser file download unless you want to either kill the ecosystem or hide from the user what is consuming upload bandwidth.

That said, for large files, I much prefer the UX of a well-designed torrent client like Transmission to my web browser. If nothing else, the downloads are reliably resumable.

Brave browser had BitTorrent client built in for a while. I tried it a couple of times as I already use Brave for web browsing on my laptop. It was a very confusing BitTorrent client. I struggled to use it, and wasted time waiting for a download to complete only to not be able to find where the files were and then they disappeared. Using a decent BitTorrent client like you say is much preferable to the one that they had in Brave browser.

The biggest problem with BTv1 was the lack of per-file checksumming, and swarm merging (i.e. individual files have shared seeding pools across torrents). BTv2 specs the latter, but I think only BiglyBT actually implements it. Having both of those features from the get-go would've gone a LONG way to fixing the dead torrent problem.

Steam & Blizzard (probably others) used to delivery games through torrent protocol in the past, before CDNs became cheaper.

When StarCraft 2 was lauched, the installer (before Battle.net installer crapware) had a complete graphical visualization of seeders & leechers.

bayindirh 5 hours ago||
Oh, story time:

Once I was using Blizzard's downloader to install something (StarCraft, Diablo, I don't remember), and it was kinda slow. I disabled P2P downloads and speed skyrocketed, and I said "Huh, this was unexpected".

When P2P downloads disabled you could see the list of CDNs you're downloading from and mine had a single IP on that list. It looked familiar. Then it dawned on to me. It was the Akamai server which we were hosting in our system room, at 15 minutes of driving distance. After a chuckle, I went to get a cup of tea, because that was entertaining than the game itself.

Then of course, I dived into whatever I was installing that night.

Edit: From the screenshots in the wiki, I remembered that the progress bar was red. It was possibly Diablo 3, then. However, I'm still not 100% sure about it.

This was in an era of much more limited upstream bandwidth. The p2p nature was obscured from non-technical users in some implementations. So on and so on. I'm sure there are plenty of writeups from that era detailing why it was a bad idea.

>might want to look up "gun show loophole"

I've never understood this. There is no "gun show loophole" anymore, if there ever was. Some states have two different standards required things like background checks and identification for gun sales between private party sales and dealer sales. If a dealer goes to a gun show, they have to background check their buyers just like anywhere else. Similarly, if a private party (in a state where they're not required to background check) sells a gun on Craigslist, they're equally unrequired to background check.

Many states, including most of the "anti-gun" states, have moved to requiring background checks from all sellers, including person-to-person transfers and even gifts from family.

The "gun show loophole" is massively overblown. There's nothing special about gun shows in it.

frumplestlatz 31 minutes ago||
That counts as many states, and most of the "anti-gun" states, which is what the parent actually said.

Personally, I think people should be as free as possible to sell goods privately without the government getting involved. It's not a loophole, it's how things should work.

If you think any of these laws prevent felons and other prohibited persons from getting guns, you must be remarkably unfamiliar with felons, and their willingness to commit felonies. Most felons I know through friends/family have a gun (often stored somewhere plausibly deniable), and it's not a particular secret.

These laws primarily harm law-abiding citizens — who were never the problem in the first place — far more than they restrict prohibited persons from acquiring guns.

The same thing will occur with restrictions on open models, but arguably the results are far more harmful — limiting the technological and economic capacity of the people and countries we have to worry about the least, leaving the playing field open for those we have to worry about the most.

This is really important. I am already tired of hoarding rclone copies of huggingface torrents and periodically checking them for bitrot. Pirateface is not a very helpful name for it though and it doesn't seem to have scripted torrent creation either.

Is hosting the same thing at 'academictorrents' actually a viable thing? In terms of peers from either send data to one another?

edit: looks like it can treat huggingface as a backstop for torrents that are otherwise not shared which is interesting, whole load of checksum nonsense I hand rolled disappear if bittorrent handles that. Except it doesn't work?

    Magnet soon No seeders yet - a torrent mints once a seeder packages this model.
So there's some per-torrent work to be done, but I don't know what that is, and I don't see how it can be based on files I have locally _and also_ be an exact match to files on huggingface. So I'm missing something here.

edit2: Looks like an implementation error. I can create a torrent from local files and upload it, but it won't have the huggingface backstop, and I can't specify it, so that doesn't actually achieve the claimed result. Before creating community torrents in that fashion would actually be of use, the submission page needs to allow pointing at the upstream.

Also, having everyone DIY a set of files -> torrent information is insane, this should not be a SKILLS.md, it should be a bash script that makes the thing.
