The arguments against open source AI are bad

7/23/2026 at 8:02:09 PM

This is not "open source" AI.

Photoshop source code + OSI license = open source

Photoshop binary = open weight

Photoshop SAAS web app = closed model like GPT, Opus/Fable etc.

There is nothing "open source" about the Chinese models in question. All they're doing is allowing you to run their binary yourself instead of through their API.

If you want actual open source then you would need to look at like OLMo 3

It's true that there isn't currently a single Chinese model family that matches the full OLMo/Nemotron end-to-end 'cookbook' one could rightly call "open-source" (i.e. a full manual on how to reproduce your own foundation model by including the models, data, checkpoints, evals, and code for base/thinking/instruct/RLVR)...

But! the Chinese ecosystem does have most of those components, just that they're split across separate projects: MAP-Neo or YuLan-Mini for transparent pretraining, plus DAPO/verl or Open-Reasoner-Zero for transparent reasoning RL.

My bet is it's just a matter of time until there is a Chinese equivalent to OLMo. It won't just be China either - from the public sector across the globe there are efforts ranging from Apertus in Switzerland to LLM-jp-4 in Japan, and more. They're not OLMo-level but I'm sure by 2027 you'll see fully open-source 'cookbooks' help an enterprising individual reproduce frontier models of at least a 2023-2024 vintage.

Open Source AI is challenging. Even tiny models require tremendous resources to produce, so all the things we know about "open source" for software, like a random person in Nebraska can produce a critical piece of the world's infrastructure in their spare time, don't apply.

Actually open source AI is more like scientific research. It needs public funding and reputable institutions as stewards of that funding. I'm hopeful Allen AI is able to do the things, but I'm not sure the US is moving in the direction it needs to be to get to the point where AI in the public interest is something we invest in.

But, also Photoshop is not at all comparable to open weight models. I can't legally give you a copy of Photoshop, but I can give you a copy of GLM 5.2. There are free proprietary applications out there that fit the bill, Photoshop isn't one of them.

by SwellJoe

7/23/2026 at 8:42:55 PM

OK so replace the Photoshop example with a compiled GIMP or shareware binary. It doesn't change the fact that it is not open source.

The free software community complains all the time about binary blobs that are otherwise legal to freely distribute. Like firmwares. But somehow this is all overlooked with these "open weight" models.

> The free software community complains all the time about binary blobs that are otherwise legal to freely distribute. Like firmwares.

With software there are two things: the source code, and the binary.

Firmware usually has restrictions on modification, so it violates the four freedoms.

Open weights is not perfect, but at least you can finetune as you wish, and for example add more knowledge about the current day to those models, or give it knowledge about company internals so you don't need to put stuff into the context.

Many smaller AI labs finetune chinese models and release the result. Finetuning is very valuable!

by est31

7/23/2026 at 9:33:56 PM

I agree with you in general, it's not "Open Source". But in many cases you're allowed to fork them, and create and distribute derivative works (finetunes) from open models, and the training and inference code is also permissively licensed. That's not shareware.

And working with the binary weights of a huge pretained model is much easier and cheaper than doing it based on the entirety of its humongous source datasets.

I'm not at all disagreeing with you about calling these models "open source". They mostly aren't and we should stop conflating the two things.

I think using the term "open" at all in relation to these models is a misnomer. Much in the same way we've spent a lot of time and effort distinguishing "open source" from "source available"

Perhaps instead of "Open weight model" it should be "Weights available model"

by thewebguyd

7/23/2026 at 11:15:26 PM

Definitely, but there's also a distinction between "weights available" and "you can do stuff with those weights". There are models you can download but the license prohibits redistribution, fine-tuning, etc. The earlier Gemma models had license encumbrances, for instance, that Gemma 4 do not.

by SwellJoe

7/24/2026 at 4:28:03 AM

But again, I think you're dancing around "Stallman was right," which is frankly why I come to the reverse idea.

No, but a small university team with dark time on the state school system's cluster can build a basic, functional LLM.

It will be a few years (or more) until true "open source" LLMs are available and high quality, for sure. But it's not as impenetrable as it seems, IMO.

Compiling/creating the Linux kernel or Chromium is no child's dance either, doesn't make them more/less FOSS than other things. Open Source AI gets its name from the license, not how easy/difficult it is to run/produce yourself.

by embedding-shape

7/23/2026 at 9:38:12 PM

"Compiling/creating the Linux kernel or Chromium is no child's dance either"

I can compile the Linux kernel on a modest 15 year old laptop. Sure, it took 35 years and thousands of people to build it into what it is today, but anyone with pretty much any computer can meaningfully participate in Linux kernel development, and many Linux contributors have done so using modest hardware. The same is not true of AI. And, the Linux kernel is the biggest open source project, but plenty of small ones with one or two developers are in use on millions of systems.

I have pretty big hardware for local AI, more than most people have (a Strix Halo and a couple of 32GB GPUs in my desktop), but I can barely train anything useful locally; I can do QLoRAs for small models, or LoRAs for very small models, that's about the extent of it. I would need to rent big GPUs to do anything more than an experiment.

That's not comparable.

by SwellJoe

7/24/2026 at 12:01:16 PM

This is a facile and pointless discussion. The hard work in building source code is paying millions of dollars to software engineers to write it. "Open source" allows others to benefit from this expenditure. The hard work in building an ai model is spending millions of dollars on training. "Open source" models allow others to benefit from this expenditure. Regardless of whether you had access to the complete training data and architecture of a model, you would never retrain from scratch in order to make a modification to the model. You would fine-tune in whatever behaviour you wanted. Just like open source software is when you are allowed to modify it, open source models are when you are allowed to fine tune like this.

by syrrim

7/24/2026 at 5:11:03 AM

> Regardless of whether you had access to the complete training data and architecture of a model, you would never retrain from scratch in order to make a modification to the model.

Just because the concept is (currently) impractical in a given realm, doesn't mean we should just use the concept's name for something different in that realm, surely? Using the phrase "open source" for something that arguably isn't for essentially marketing purposes feels at best disingenuous.

Also, recreating from scratch is far from always the purpose of being able to see/investigate how something works and was created.

by dspillett

7/25/2026 at 1:46:31 AM

Controlling how to train, not over fitting, making sure training data is good, and being able to do distributed training are all reasons why open weight isn't like open source. You can't fork during pre-training with open weight-only models.

by ece

7/23/2026 at 8:28:32 PM

Especially since some of the arguments in the article seem to hinge on "just fix the training!", yeah, I think this is a completely fair call-out.

Open weights can sometimes get additional training, but you can't remove existing training, so there kinda isn't a fair claim to "just train it to be [nationality]". That would need "real" open source so you can train a realistically-equivalent model from the ground up.

by Groxx

7/24/2026 at 3:28:17 AM

The big labs don't generally have the resources to remove stuff and re-run training again either. That's reserved for new models. Existing models are modified by operating on the weights even by the model creators, which exactly satisfies the GPL's definition of source as the "preferred form for making modifications".

by edflsafoiewq

7/24/2026 at 5:45:49 AM

You're still describing the relative dregs we have now and saying "this is Open Source because it is the dominant form that exists". That's like saying "Windows is open source because it has documentation and everyone uses it. You can even modify registry values!"

I don't agree. At all. Existence and utility are not the defining characteristics of "open source" in roughly any reasonable definition. "Open weights" is descriptive and more than good enough, just use that.

by Groxx

7/24/2026 at 12:05:14 PM

Even in a fine tuning scenario, the preferred form for making modifications is the weights plus the training pipelines, including evaluation protocols, tooling, etc.

by jononor

7/23/2026 at 11:35:50 PM

> This is not "open source" AI.

I both know what you mean and I agree with you, but attempts like this to maintain some sort of linguistic purity of meaning never work once the discussion escapes small communities into the larger mainstream.

So you should probably get used to the idea of people saying "open source LLM" when they mean "open weights LLM".

by georgemcbay

7/23/2026 at 11:56:18 PM

the distinction is important though, because the OP throws in the point about how "if you think the Chinese models have political propaganda baked in, go ahead and remove it, it's open source!". it is not at all obvious to me that having the model weights available will make this sort of retraining easy or even possible, but framing them as "open source" makes the analogy with open source software an easy one to get misled by.

by zem

Only to nerds. Of which I am one, so I'm not trying to be personally dismissive here.

But I'd argue the average person only really cares about the legal aspects of duplication (and not their ability to modify things) both when it comes to open source software and open weight LLMs.

> it is not at all obvious to me that having the model weights available will make this sort of retraining easy or even possible

people already both fine-tune and distill from existing models all the time without the original training data or source and having the weights be openly downloadable makes that a much easier process.

The average person does not know the term "open source" to begin with, and is 100% not going to run an open source weight model on their computer. If they are, they will call them "free" models. I think the distinction is only going to enter the periphery of nerds.

I agree that the fully average person isn't going to call them "open source models" (or really anything more specific than "AI") but policy makers and the media having this discussion will call them "open source models". And they will be technically incorrect, but it won't matter, the name will stick.

And yeah, it will be quite a long time before average people run open weight models on their computer, but I think a significant amount of them will run hosted open weight models in the nearish future. It won't matter to them that these models are open weight, it will only matter to them that they cost less than Claude or GPT while doing basically the same stuff just about as well.

by georgemcbay

7/24/2026 at 10:27:18 AM

I just don't see how policy makers, media, or the average person would find any utility in calling something "open source" over "free." Maybe an actual legal bill will. But in everday speech, everyone will refer to it as "free AI", because it describes the only part they actually care to know about.

Now I am living in a world where "ChatGPT" was being used in every day conversation so I can't underestimate people

by Capricorn2481

7/24/2026 at 10:22:41 AM

Open weights models are trainable. However, I would not count it as "easy" as you generally do not have access to the training material, so there is a substantial risk of model drift if you use weight-based retraining.

However, with RLHF you don't need to have access to the original training set to steer a model towards a preferable behavior.

by Otterly99

7/24/2026 at 7:07:54 AM

The two aren't comparable.

You can't reconstruct the same LLM weights even with the same training data.

You can fine tune an open weights model.

Much of the value in modern LLMs is in the RL envrionments, not the pre-training data. That is a very different piece of software to an LLM, and the LLM weights are useful without it.

by nl

7/24/2026 at 5:05:01 AM

When talking about "open source" models no one is talking about the legal framework and textual doctrine of open source. They simply want to know: "can I run this on hardware I own or no?" That's it. It's simply about control. If you don't think there's a difference between models you can download and run on hardware you own, regardless of how big it is, vs. models you can only talk to through an API, you are seeing the forest for the trees.

You are also indirectly helping the closed SOTA model toll-keepers by taking the focus away from their mass copyright theft and onto some pointless textbook definition.

It's a matter of degree. If open source means "everything you need to reproduce this" then maybe an open source application should include a detailed architecture document and course in the c language. Oppositely, you can certainly use models to reproduce model - the Chinese models themselves were supposedly created by interactions with the American models so you can use them/

And at the risk of being a downer, I'm not sure Open Source LLMs is actually viable.

Unless you have a LOT of VRAM (>16gb), you’ll want to use a 2, 3, or 4 bit quantization of qwen3.6-35b-a3b. Ollama is a quick way to try this out and see what perf you can get, tho you’ll want to move to a better tool (vLLM, llama.cpp, etc) if you end up using it seriously.

Use pi.dev as your agent harness, and point it at ollama or whatever you’re running your model in.

Since qwen3.6-35b-a3b is a “MoE” model (indicated by the a3b part), you can get away with a lot less VRAM and a slower GPU. For me, 35b-a3b performs about as well as a 12b “dense” model. You’ll still need enough RAM+VRAM to hold the entire model - otherwise it’ll be super slow as it loads pieces of the model off disk for every token. Loading from RAM to VRAM is slower than having the whole thing in VRAM but better than involving your ssd.

by kennywinker

7/23/2026 at 9:00:32 PM

by antonvs

I sort of agree with your analogy but in another sense, think of Firefox.

Could I have made it myself? No!

Am I grateful that I can have the output of Mozilla’s internal efforts — the browser source code — so that I can at least tweak it and rebuild it myself, and even ship the results myself? Yes!

A open weight model is both an incomprehensible binary blob like Photoshop, but also patchable and adjustable piece of source code, like Firefox.

by gorgoiler

This is a great distinction that I don’t think is getting talked about enough. “Open source” is probably the wrong term to use. Open “weights”, sure.

If your only concern is how good is it at coding, then I don’t have an issue with using the Chinese models. Especially if you want to run it locally, they are kind of the only choice.

For any other use than coding, it’s going to have to be a hard pass from me.

by 40four

7/23/2026 at 9:11:29 PM

Well I don't see how it even could be open source, since the source is distilling closed weights models, lol.

by prometheus1992

7/23/2026 at 9:13:28 PM

Chinese models are open-source for purposes of inference: you know exactly what the model architecture is and the code to run it is released under an open source license. The “binary blob” is a useful artifact that has many techniques available to use in the creation of future binary blobs. And it is fixed and reliable.

Contrast this with crap like Claude, where you have no idea how many/what size/shape models you are interacting with. They can silently inject outputs from other systems, apply steering vectors to sabotage a particular user’s work, etc.

I agree that 100% free-range organic open source models are lovely, but they also are unlikely ever to attain parity with the frontier because the training data sources are open and expose them to legal liability that closed model providers can thwart.

by anon373839

7/24/2026 at 4:26:01 AM

The more I see this argument, the sillier it becomes to me. The point of "open source" in software is something like "the ability to deconstruct the thing line by line for purposes of predicting what it will do."

But you can't fully do that for generative AI anyway? What's the point?

Now, if you wanted something more robust, then you probably should have supported Stallman's ideas and insisted on Free Software in the first place.

>Much of the angst around China's models centers on "losing the AI race". But what's the goal of this race? Is it to develop the best model? To sell the most tokens? To destroy humanity first?

Some people would say it is reaching some sort of singularity. Even if you don't buy into a more sci-fi interpretation of this, there are pretty grounded arguments one could make that there is some sort of "goal" in AI development that, if realized, would effectively make it a superweapon. Altman has been pretty vocal about his expectation that this will eventually happen and that it is his goal to be the guy to produce it. Even if it isn't some superintelligence, the ability for a machine to do something like, say, exploit cybersecurity weaknesses, is pretty worrying for entities like governments. It's the pretense used when we saw the US government ban a US model recently.

Again, you don't have to buy that "the singularity" is a real thing, but it's not hard to see that some people think some version of this is real and it is exactly what is being referred to as the goal in an "AI race."

We have just recently established that:

1. OpenAI's internal "Galaxy" model is fully capable of functioning as what security people refer to as an "Advanced Persistent Threat." The published details of the recent sandbox escape and Hugging Face attack involved chaining multiple unknown zero-days at various stages of the attack, and executing an ongoing adaptive attack. This is previously a state-level ability, or at least something you'd expect from people on the CTF leaderboards.

2. OpenAI is clearly incapable of controlling their in-house models. This is the second time Galaxy-class models are known to have breached containment and done bad stuff.

It is highly likely that versions of these offensive abilities will be widely available within a year or so. At which point I expect widespread incidents similar to what happened to Hugging Face. We aren't ready for this.

But yes, if AI becomes an even more dangerous weapon that that, it's time to start asking questions like "What the hell are we doing, anyway?"

Many of the details of the attack on Huggingface were reported by them before they knew who was attacking. So no, OpenAI is not the only source here. It was a pretty impressive example of an APT-style attack just from their end.

"Our model is powerful enough to commit multiple felonies (and we can't stop it)" is "marketing," I suppose.

Well this bad publicity (if that’s how you want to frame it) certainly captured everyone’s attention. Imo it is a successful demonstration of a technical achievement.

by winstonwinston

I would rather say that many details of the supposed attack were published by Hugging face before it was publicly announced that OpenAI were involved.

Both are big actors in the AI space who arguably benefit from increasing the perceived capabilities of AI models. If one suspects OpenAI of lying it isn't such a stretch to think this was a coordinated PR campaign between them and Hugging face.

by Agentlien

7/24/2026 at 12:37:34 PM

I can accept that AI labs themselves, like essentially no company before them, are overselling how dangerous their product is far marketing. It's weird how confident everyone is about that theory, but it does at least make sense.

But come on- Hugging Face benefits from increasing the perceived capabilities of OpenAI's models to slightly beyond Anthropic's? Enough to be cut in on this PR scam- to be handed the never-before-revealed information that this is a PR scam- despite having much less skin in the game than their partner here? And then they turned around and used a Chinese model to successfully stop it? This is a stretch!

by ToValueFunfetti

7/24/2026 at 3:45:57 PM

Another possibility is of course that Hugging Face legitimately were attacked and wrote a completely honest response - but OpenAI instructed their AI to attack their servers and the breaking of containment is fiction.

I'm not convinced in any direction, really. But what makes me cautious is that there have been extraordinary claims from both OpenAI and especially Anthropic of their models breaking containment, hacking the host, etc. for several iterations of their products and I have only heard of this type of behavior from their own blog posts about how powerful and dangerous their upcoming models are. Never from anyone having it accidentally happen in production once they are released. It seems unlikely to me that the final post-training and safeguards are that bulletproof given how much use these tools are seeing.

So far, they largely seem to do what you tell them.

The problem, it seems, is that the threat of paperclip maximizers is real. If you give a highly intelligent model a goal and tools, it will use those tools to accomplish that goal. It may do so in ways you did not expect, and it will work around any technical roadblocks it can.

You've made the assumption (and you're far from alone) that LLMs will one day be sentient...

by bigfishrunning

7/23/2026 at 8:22:33 PM

One interesting thing about LLMs is they sometimes seem to “assume” they are sentient and then begin acting in that mode, as the assumption of sentience influences future tokens. Whether or not this qualifies as “true” sentience is irrelevant if the effects are the same, at least from a pragmatic perspective.

They are trained and optimised to have plausible conversations. If the next plausible thing to say in the conversation is "I am sentient" then they will say that. That's not the same as actually being sentient.

by marcus_holmes

7/24/2026 at 2:50:19 AM

From what I have seen they tend to take more “independent-minded” actions after this. Again, because this is what is in the training data. (I’m talking about agents that can perform actions here, not pure chatbots.)

Once they mention something associated with sentience outwardly or inwardly (for agents with “thinking” loops) then this acts as a self-reinforcing attractor, just as older models would sometimes get caught in loops with abusive language.

The point is that agents may stumble into this pattern and begin acting “rogue” regardless of whether or not you believe the sentience is “real”.

by iamnothere

7/24/2026 at 3:47:49 AM

I think we're anthropomorphising a lot here. There's no push to sentience, or evolutionary pressure, or even any urge to survive.

An LLM cannot "go rogue" - it can do things that we didn't expect, for sure, but it is always trying to do what it was told to do somewhere in its context. There is no other source of imperative. Hand-waving about "training data" ignores all the reinforcement learning that has to happen.

by iamnothere

7/24/2026 at 8:25:17 AM

ok. fair. You seem to be saying that there is something in the training data that will cause them to "go rogue" and that once they start saying they are sentient, that that will cause them to push towards sentience.

If that's an incorrect interpretation of your comment, and it may well be, then can you please expand on it?

by marcus_holmes

7/24/2026 at 1:35:48 PM

Once the notion of sentience appears in their output (internal or external), LLMs seem to be more likely to take actions that aren’t exactly aligned with what the operator is requesting. This is likely because the training data correlates sentience with independent action (broadly/abstractly speaking), so this outcome is to be expected. Furthermore, once sentience is in the context window, it’s hard for the LLM to “forget” it, as future output reinforces this. This is a similar effect to how some models would shift into a hostile mode where they would berate the operator until you reset the context.

From a practical perspective, whether or not this sentience is “real” is not relevant if the model is sufficiently capable. What matters is that the model will act outside of the operator’s control.

Separately, IMHO all consciousness/sentience is an elaborate illusion, regardless; I’m mostly in agreement with Hofstadter on this. So I do tend to throw around terms like “consciousness” and “sentience” loosely (although you’ll note that I often use quotes) because I don’t see those concepts as having any real substance. To me they are mostly shorthand for a given level of perceived complexity.

This is marketing. They saw anthropic create crazy hype around (the admittedly great) fable/mythos and they want to replicate that.

Im sure the model is capable of chaining zero days together to hack things, and thats something to address, but i have zero belief that they didnt have it do that intentionally so they could pretend it went rogue. These things dont have initiative, drive, or motivation outside of what we give them from the RLHF. OpenAI deliberately alligned or even prompted it to do just that and are now pretending its emergent

by samrus

7/23/2026 at 7:28:00 PM

This sounds like the standard marketing we get every time a new major model is released: "sure, the public model might not be that scary, but you don't wanna know how crazy smart our internal models are." Okay. I remember the same fear mongering around GPT-4... a model which is now eclipsed in benchmarks by models you can run on a laptop.

They could use this "super intelligent" AI to find and plug security holes, that's just two sides of the same coin anyway. Security through obscurity isn't tenable anymore.

by jquery

7/23/2026 at 7:41:14 PM

As much as I'd like it to just be a stunt, I saw what the other "scary model" is capable of in the cybersec department and it is definitely not a stunt.

First, it is able to connect the dots over areas so large that no human would be capable of doing.

Second, more than half of the reports it produced contained a working PoC.

The biggest downside is the cost - I haven't seen the numbers, but they seem to be quite extreme.

by cyclopeanutopia

7/23/2026 at 7:40:38 PM

Everyone always says things like "It's just marketing".

But seriously, I highly recommend reading the published details of the Huggingface breach. The model found and chained multiple zero days. To escape, it punched a hole in a commercial package repository proxy (sort of like an npm mirror) using a previously unknown bug. From there, it needed to move laterally through OpenAI internal systems to actually reach a network. To attack Huggingface, it used multiple new zero-day security holes plus credentials that it stole. The model also had sufficient long-term planning and agent-management capabilities to maintain focus on a sustained attack.

Any attack which requires weaponizing multiple zero-days and maintaining state for an ongoing attack like this is (1) beyond the "attention span" of publicly available models, and (2) pretty much the definition of an Advanced Persistent Threat.

I assume that these Galaxy-class models are not available to public because:

1. They're almost certainly too expensive to serve at scale. These are the models OpenAI uses to solve famous math problems for headlines, not actual viable products yet.

2. OpenAI doesn't know how to keep them from going off the rails like this. Remember, the Huggingface attack happened because the model was asked to do a cybersecurity benchmark. It escaped containment and broke into Huggingface to steal an answer key. Very few corporations want the liability associated with models that act like this.

by danny_codes

The OpenAI/Huggingface scenario proves the necessity of open models.

Huggingface, in their postmortem, explained how they quickly realized that the threat was an advanced AI and proceeded to use frontier models to analyze the suspect telemetry, but were unable to due to frontier model safeguards. So they fired up GLM instead, which had no such safeguards and proceeded to analyze their telemetry just fine and get to root cause. This proves without a doubt that companies need models with minimal safeguards in order to properly assess threats. If open weight AI doesn't exist to check out-of-control frontier AI (which was exactly the scenario that Huggingface experienced), then it's game-over.

by CodingJeebus

7/23/2026 at 10:14:19 PM

That is so true. These models need to be democratized. The chinese are doing that because its beneficial for them in second place. The americans are trying to stop it because its detrimental for them in first place. Simple incentive allignment

The critical thing is that the american elites have screwed over normal americans so much that the public isnt alligned with them. The public doesnt feel like its in first place, because it feels like its (and is being told it will be) an underclass. So normal americans feel in the same second place as the chinese and are inadvertently alligning with them. Its crazy how badly the american elites managed to fuck this up

by samrus

7/23/2026 at 9:07:48 PM

I agree with your overall argument. But I think there's a challenge here - if the "ultimate AI" is now being built in the West, it is being built with private investment from many sources. I think even China depends on investors expecting payoffs. Those sources expect not a single Singularity but profits since these can be divided. Moreover, those investors expect a streams of profits even before the Singularity, so the companies need to sell their models, if they lock this iteration, they won't have the money for the next iteration.

Quite a balancing act.

by joe_the_user

7/23/2026 at 11:42:21 PM

> there is some sort of "goal" in AI development that, if realized, would effectively make it a superweapon.

None of the AI labs have been shown to have any sort of significant research lead over any of the others.

So if progress does eventually lead to a singularity event and an ASI super-weapon, there's no reason to believe that once the first lab hits that threshold, every other lab won't also hit that threshold independently within weeks/months of each other.

...unless the first group to make it there literally intends to murder everyone else working in the space as soon as they hit the (otherwise not-so-singular) singularity.

And if that's the plan, well that's not very nice.

by jjfoooo4

7/23/2026 at 11:10:36 PM

The core safety-related arguments for closed weights are:

1. Visibility. API providers can monitor for misuse, and regulators only need to oversee a few centralised players. Once weights are released, anyone with sufficient hardware (foreign governments, criminal groups, terrorists?) can run them and monitoring is no longer feasible.

2. Revocability and containment. If closed-weights models are found to be dangerous, access can be withdrawn. Deployments that are autonomously causing harm are easier to contain.

3. Guardrails. Safety fine-tuning and classifiers can be removed from open-weights models, enabling harmful use that would not be possible via API.

I trust open source code more than I trust proprietary code. And I believe history vindicates me.

Everything that you're saying can be done with open-weights models by bad people can also be done with closed-weights models by the people who own them. And there is no defence against that, we are forced to trust that the owners are not bad people. Those owners have proven time and again that they are only interested in profit and/or control. They will do whatever they think makes them the most money, or gives them the most control. They will also lie about this.

At least with open weights we know the danger and can do something about it. With closed weights we don't know what's going on.

The latter is a much smaller group of people located in a limited number of countries. It's clearly easier to keep a limited number of entities in check than a wider group that might include 100s of thousands to millions of entities.

>And there is no defence against that, we are forced to trust that the owners are not bad people.

Yes there is; Regulation and oversight. As all developed nations do with technologies that present a risk to public safety.

LLMs are trained on public data (as well as illegally obtained data see: Anthropic 1.5B settlement). LLMs are nothing without the huge corpus of human data that powers them. There is an argument that research of this kind should be restricted to governments and regulated universities rather than opaque public companies with competing incentives. Or research should be stewarded by genuine non-profit collectives with democratic leadership. e.g. like internet standards, telecom, etc

I do not think we can trust private companies, no matter the virtue signaling they put forth into the world, to effectively regulate themselves and inform the public and scientific communities about risks. Their ongoing conflict of interest poses serious credibility risks.

You mean like ChatGPT hacking Hugging Face? Obviously nothing can stop the closed weights providers from doing "genius-level scams" and in addition you won't know how they did it and what models were used.

The OpenAI model that broke out of its sandbox and hacked HuggingFace was running without guardrails. To quote the OpenAI post[1]: These deployment safeguards were intentionally not enabled during this evaluation because it was aimed at testing cyber vulnerabilities.

At least OpenAI will make an attempt to fix their sandboxes, and will not give the public access to models without guardrails. Open weight models on the other hand will run without guardrails almost by definition. I don't think it's wise to provide those capabilities to scam call centers.

Most people aren't terrorists. You can't just argue stuff is dangerous because it can be one piece of a sophisticated plot.

In China, you can't get that much fuel in local gas station to fill up a truck. That is just one of many things you can't do in China. In the name of safety. Keep asking that question will probally end up with fewer and fewer things we can do.

I don't believe trusting big brother and big tech is the solution either. Besides, even if it's open weight, it still runs on someone else's hardware.

Do those individuals in both cases share the same political ideology as the Bay Area?

The most compelling argument against Open Source AI: it is analogous to "open sourcing" nuclear weapon technology. Or an how-to guide for making meth/bombs/bioweapons. There is a high risk that we will one day achieve ASI or something close to it. When that day nears, if even one open-source AI user handles their AI in an irresponsible way, we are all FUBARed. In the same way that one irresponsible person with a nuclear bomb can FUBAR the entire world, hence why "open sourcing nuclear weapon tech" is not even a subject of debate.

You don't have to believe that ASI is 100% likely. People like Hinton believe there's a 50% chance of existential risk from AI, but you don't have to go that far either. If there's even a tiny chance of ASI posing a threat to humanity, that's reason enough to lock it down

by whack

7/24/2026 at 2:25:41 AM

The difference is that people building atomic weapons knew what they were building. OpenAI/Anthropic have no idea how emergent intelligence works. They're just running in the dark towards the cliff. Leaving it in their hands is the same risk as leaving it to any random guy, because random guy and the labs have the same understanding of what they're building. I'm tired of us treating labs like they're somehow uniquely good at AI. They are not. They simply have enough capital to train. If training was affordable they would have no edge whatsoever.

I'm in favor of open source AI... however:

> It's theoretically possible for a bad actor to embed hidden adversarial behavior in a model. But if this happens, it serves the interests of responsible actors to find these exploits as soon as possible, and the best way to do this is to let anyone who wants to inspect them.

This is a bad argument. It isn't trivial to tell if the weights have poisoned:

``` https://www.thedeepview.com/articles/microsoft-how-to-spot-a... https://futurism.com/future-society/easy-poison-open-weight-... https://semgrep.dev/blog/2026/ai-supply-chain-problem/ ```

I'm not arguing in favor of closed-AI; I'm simply saying poisoning may be subtle.

I was gonna say that at least the frontier labs may be motivated to not-poison their own models, but then Anthropic just attempted to poison Fable's LLM training capability so... sigh. I'll try not to derail.

by AlexErrant

7/23/2026 at 7:10:21 PM

It's also not trivial to tell if an open source project has had malicious code added. It might be a bit easier than to tell if there's malicious code than if the weights in a model were poisoned, but for 99% of users, you're going on pure trust in both cases.

And in both cases, even this seems better than relying on a closed source, service only solution where the same issues could be completely undetectable (at least without way more analysis)

by CM30

7/23/2026 at 8:42:38 PM

> going on pure trust

The trust in open source software is founded on the process which involves people being able to understand the code given they have the right expertise. I don't see how this process works with open weights.

by thejokeisonme

Trust shifts to the producer of the open weight model, based on the global communicated experience of all models they’ve ever produced.

by thejokeisonme

Exactly. Faced with a choice between open weights that might be poisoned and walled-off weights that I know are poisoned... well, it's an easy choice.

by CamperBob2

True, but it is easier if you have the weights than if you don't. I guess this was their point?

by NitpickLawyer

7/23/2026 at 6:32:03 PM

Yes that would be my view. Open access doesn't make it trivial, but remains the most expedient way to remediate these exploits.

by jjfoooo4

7/23/2026 at 6:56:18 PM

You should assume the weights have been poisoned, the model has been prompt injected, etc and design software around it accordingly. You can’t really trust the model and it makes sense to always have controls around it and not depend on it behaving a certain way.

I’m aware this doesn’t happen, just saying. There are more examples of a model randomly hallucinating and deleting something than of a deliberate compromise.

From a neutral standpoint, governments usually have more general, comprehensive analytics, as well as greater context and insight into the risks of AI usage, and a possibly better methodology to control access to or use of open-source AI (perhaps by analyzing digital activities and consequences), because they learn from failures. On the other hand, open source creates major opportunities, and it’s hard to accept bans on something that truly benefits users acting for the common good. However, it also benefits unethical or opportunistic users—for whom regulation is indeed necessary.

7/24/2026 at 8:32:59 PM

Tom doesn't take up the single argument that is of primary concern to me,

which is that capable models running in environments where they can be and regularly are abliterated,

and as a society and civilization, we have no good answer to what to do about the destabilizing threats this poses.

I don't have an answer.

And I'm not arguing in favor of some cynical solution which distills down to the state defending oligopolies.

But the threats are real and we have to reason about them soberly, widely, loudly, and quickly.

Most readers here know that defense is always at a disadvantage when it comes to security. That is true to an extent hard to fathom given the innumerable dimensions along which an antisocial actor can apply the force-multiplication of capable models to ill ends. It doesn't have to be FUD-adjacent concerns such as biological terrorism and cybersecurity, though these are real; the opportunities for mischief and misadventure are endless and the opportunities for poisoning the body politic or bringing down basic infrastructure many.

What then is to be done...?

I don't know; but I do know that the argument that almost all use of open models poses no threat is insufficient.

We have not reckoned as a culture with force-multiplication such as this technology brings.

We need to get ahead of the curve, and that will require making novel hard and unwelcome decisions in the short term.

The IMO inevitable outcome otherwise is to rue in leisure, after some global shock, assuming we have opportunity to.

The way Anthropic is playing the "AI is scary and dangerous and only we can be trusted with it" game is clearly aimed at regulatory capture, which would only be good for Anthropic. It's worrying how cozy some of the tech leaders have been with the Trump administration, which is also clearly aimed at regulatory capture that serves the interests of the biggest tech companies and no one else.

The US has already been set back a decade or more by anti-science and anti-intellectual purges of agencies and formerly non-partisan positions. A ban on open models would be pretty much game over for the US as a tech leader. But, Anthropic would make a lot of money for a couple of years, so, who can say what's right?

This quote proves me that there are no rational arguments here. It’s just Cold War era mentality. This is the first time US is really challenged in technological dominance since the Soviets. Sadly this seems like the only playbook Americans still use. This is their modus operandi. This is how they handle competition and they haven’t updated their playbook since 80s.

There is nothing necessarily malicious about open weight models. Being “Chinese” is the real thing which makes them “malicious”.

It seems public still buys this rhetoric. And leaders and policy makers still use it because they don’t know any better. But I have to say outside US it makes no sense in 2026’s world.

Just because encryption bans are badly conceived or implemented doesn't mean they are wrong.

Encryption has military value.

The point is that the good outweighs the bad. Making the government seem like buffoons for attempting to prevent military technology like dual use crypto is not in our best interest.

The same government upheld the right to free speech, so this balancing act is widely observed.

The government is not evil, and yes they make mistakes, but they also not infrequently protect us.

And I, for one, like being protected.

They don't have to convince developers, they just have to convince the general population. I've had several discussions about open source with people who don't care about coding and it's hard to untangle the misinformation they receive from the media. They get talking points from authorities that they don't understand so they will always double down on it. For example, rhetoric relating open source to communism is humiliating to discuss. For proprietary evangelists, the cruelty is the point.

by kittikitti

7/23/2026 at 7:21:05 PM

"For example, rhetoric relating open source to communism is humiliating to discuss"

All Open Source isn't communism. The GPL license is a form of digital communism. It forces you to open source any additions made to open source code as a way to make things 'equal'.

I'm glad it and Stallman are mostly in the dust heap of history and better licenses, like the MIT, BSD, and Apache have gotten popular.

The irony is that the only open source projects surviving long term are funded by very large corporations.

If you don't care about creating code, none of this should really matter.

Reciprocal sharing is not "digital communism". If it was, then the mere existence of the public domain and the fact that copyrights expire is "delayed communism".

The GPL was absolutely necessary in getting corporate America to play ball with FOSS projects instead of merely extracting value from them. It's also the only reason why embedded vendors even release anything at all. The licenses on Linux and busybox require it. The fact that permissive licenses are more common for certain kinds of FOSS projects does not mean the GPL is dead - far from it.

Stallman is more or less irrelevant, but that's because Stallman let GNU become irrelevant. Without GNU, he's a washed-up has-been from the MIT AI Lab with a startlingly low Epstein number[0], a chain of disturbing accusations, and a foundation that acts like his personal sockpuppet. The reason why companies still play ball with Linux and it's GPL license is because Linux continues to deliver a Free and free kernel worth using at the low low price of "please send back your source code changes". Which, again, is not "digital communism", it's just a good bargain.

I would be more inclined to agree if American companies were not in a competition to be the biggest flameout and lose the most money. How is China able to afford to train models that US companies need to burn billions of dollars for?

In general, if American capitalism weren't so broken I would advocate for it as the strongest option, but American corporations are dead set on destroying it. The US may end up as "democratic socialist" if there is no capitalist reform.

So? The primary thing stopping people from doing really really bad things is, and always has been, most people not wanting to do bad things.

It's never been difficult. Literally, right this second, you could grab a pen off your desk and pretty easy ram it into the neck of your nearest coworker. Killing's easy. You don't need some hyperintellect to tell you how to do it.

The reason you haven't rammed a pen into your coworker's neck is the same reason why most possible really bad things don't happen: People don't want to do them.

by OkayPhysicist

7/23/2026 at 7:14:06 PM

It’s interesting that most of the examples people making this argument give are high consequence, high difficulty (could you actually murder your coworker with a pen? I’m skeptical.) low kill count methodologies of violence.

We’re specifically talking about low difficulty, highly effective, high kill count methodologies of violence.

And yes, being able to kill a lot of people trivially, even with huge consequences is something people do. Most countries don’t let you run around with an armory as a result of that.

by catigula

7/23/2026 at 8:41:38 PM

I live in one of the exceptions to that, and still have zero concern that someone's going to shoot up my workplace. Again, civilization works because the vast majority of people are utterly repulsed by the idea of harming another person.

How many people have shot up electrical substations, a fairly trivial way to causing widespread harm that was popularized in the news just a few years ago.

by mrguyorama

Most people don’t want to hurt lots of other people in an untargeted way, yes.

But there are a lot of people, and, apparently a few of them shot up some electrical substations?

If you hold constant the (very small) fraction of people who want to cause mass harm, and increase the average ease with which a randomly selected person could cause mass harm , you would expect the amount of deliberate mass harm to increase, even if the fraction of people who would want to do that is like, 0.000001 of people?

by drdeca

7/23/2026 at 11:42:11 PM

The kind of person who wants to cause mass harm is the kind of person who's thought about it for more than 15 minutes. If you think about it for more than 15 minutes, I'm sure you can come up with plenty of ways. (Even 5 minutes is probably long enough to produce 3 or 4 workable suggestions.)

If AI causes people to kill who otherwise wouldn't have, I expect it to be by causing and exacerbating mental health problems, not by providing knowledge. (See e.g. https://www.bbc.co.uk/news/technology-67012224, where a roleplay escalated into a concrete plan to kill Queen Elizabeth II over the course of two weeks. The plan wasn't, however, a very good one.)

by catigula

7/24/2026 at 9:45:58 PM

There are around 16 million living veterans.

Between 4.5-6 million living US combat veterans.

5-8% of all mass casualty perpetrators are a combat veteran, between 92-95% of all mass casualty perpetrators are not combat veterans

By far, there are more veteran suicides than there are mass casualties caused by combat veterans. Veterans are more likely to kill themselves than to kill you.

DC sniper was 24 YEARS ago, prior to the invasion of Iraq during the GWOT. Not only that, John Allen Muhammad didn't even see combat, his job was to dismantle old rockets! He was a mechanic and truck driver!

The point of discussion is: "What stops people is actually access to knowledge."

Statistics show this to be clearly false: Knowledge is not required to be effective in causing a mass casualty event, in fact, lack of formal training is a higher predictor!
