In short

Clement DeLong (Hugging Face) argues open-source AI is safer than frontier proprietary models, discusses government attempts to restrict frontier releases (GPT-5.6), and predicts the next AI phase will be “model routing” across many models rather than one dominant lab. He also covers Hugging Face’s open-source business traction, local models, evaluation/benchmarks, and Europe’s ability to build a frontier ecosystem.

Guests

Theo Jaffe and Sofia Puccini interview Clement DeLong, Hugging Face co-founder and CEO (open-source AI platform).

Key claims

Distillation is common but not the main driver of capability; competition is healthy. Open-source models are structurally less dangerous and harder to restrict than APIs. Routing redistributes value from frontier labs to the long tail. Local models enable privacy and offline use.

Notable examples

GPT-2/“too dangerous” precedent; GPT-5.6 release restriction; Stanford study: ~70% of ChatGPT queries answerable locally; Lama.cpp runtime; Open Router “Open Fusion”; Anthropic vs Alibaba “distillation attacks.”

0:00I think distillation is a very common practice that everyone is using. It's something that everyone uses, but that is not the main reason for success. Like if you suck, you suck with or without distillation. It's hard for me to say like, oh, poor Entropic, poor OpenAI, you're getting unfairly competed with when you're like the fastest growing company in the world. If anything, I think they need more competition than less competition. Because we're heading towards a world where a few companies are completely dominating, concentrating all power, all capabilities, all wealth. And that's much more dangerous than them maybe losing a couple of billion dollars of revenue.

0:47As AI models become more powerful, governments are beginning to ask new questions about safety, regulation, and who should control access to frontier technology. In this episode, Theo Jaffe and Sofia Puccini sit down with Hugging Face co-founder and CEO Clement DeLong to discuss why he believes open source AI is inherently safer. what Hugging Face reaching$100 million in annual recurring revenue says about the business of open source, and why the next phase of AI may be defined by model routing rather than a handful of dominant frontier labs. They also discuss GPT-5, AI regulation, local models, Europe's AI ecosystem, and the growing importance of competition across the AI stack.

1:35And we are back with Clement DeLong from Hugging Face, his second time on MTS. Hugging Face is basically the open source AI platform. So, Clem, welcome back to MTS. Absolutely. Yeah, so, well, go on. I think we're about to say the same thing. Yeah, we were talking about this interesting recent piece of news where basically the government is going to restrict GPT 5.6's release sort of unilaterally, basically without precedent. I don't think the government has ever asked a Frontier Lab not to release a model before. Certainly a government has not asked a Frontier Lab to be able to oversee which customers the model is released to.

2:20This seems very unnatural. What are your takes on this? Yeah, so it was funny. I was in D.C. last week, so I was kind of like had some sort of front row seat to what was happening. Interesting anecdote is that we bumped into Tom Brown there, like the co-founder of Entropic, and we were like, oh, it seems to be like a change of staff or something like that before it was made public that they changed a little bit the people talking to the White House there. Listen, I mean, what I've seen, what I'm hearing is that there's a lot of interest from a lot of people in the USG to really understand the risks of AI and take kind of like a safe approach to the deployment of frontier models.

3:14To be honest, I can't really blame them because of the fact that the frontier labs were basically doing marketing for the past few years. If you remember, GPT-2 was too dangerous to release. It was like four or five years ago. And so I don't really blame them for doing things like that. I just hope that progressively we'll get a little bit more transparency about what is safe, not safe. So more focus on transparent evaluation of models and things like that. I also hope that it's going to stay contained to, you know, a few frontier journalist models, because frankly, I think they're the most dangerous ones, right?

4:01And also, you know, these companies are trillion dollar companies with armies of, you know, DC people, so they can kind of like deal with it. I hope it's going to stay contained to that and not permeate to a lot of different players. For example, startups, small companies, academia, or people who don't necessarily have the money, the size, the ability to really deal with these things. That would be kind of my main concern. Totally, yeah. What we were just talking about before Or was just like, could this be applied to open source companies and models in any way? Like, is there a way that the U.S.

4:47government could come in and restrict open source companies, either practically or legally? I don't think so, because, you know, I think open source models are inherently less dangerous than kind of like the models that are getting restricted now. because, you know, these models are a little bit ahead in terms of like being closer to the frontier. Also, open source models are less generous. They're more specialized. And it's just like nobody or very few people focusing on building dangerous like cyber security capabilities. So it's like a little bit different than kind of like the proprietary labs.

5:30So, yeah, so I don't think it would make sense. I don't think it's going to get to open source just because of some of these differences. A more high level, you know, I think in general open source AI is much, much safer than kind of like proprietary AI for a bunch of different reasons that I've talked about in different outlets. But yeah, so I think the approach there is going to be, hopefully it's going to be a little bit different between kind of like closed source, proprietary frontier models, and then the rest of the industry and the ecosystem that has, in my opinion, posed much less danger, much less threats, where we want to keep kind of like, you know, supporting and building up to focus on, you know, competition, to enable kind of like little tech, small companies, everyone to be able to basically participate in AI.

6:28I agree that open source models are less dangerous now, but in six months, if trends continue, you're going to have an open source model from somewhere with mythos-level capabilities that freaks out the government. And you could imagine them at least wanting to restrict open source models at that time. I'm not that sure, because there's this weird thing where basically the most dangerous things usually are not so much developed in open source. You know, maybe it's this thing that people say, like sunlight is the best disinfectant. You know, like the funny thing is that sometimes safety people are talking about the nuclear bomb.

7:12A nuclear bomb has never been built in open source, and I think it would have never been built in open source. It's been built in a closed source, you know, proprietary team with billions of dollars of, you know, of resources. So it's much less like, you know, some players and some others. So I think there's also a path where open source keeps building kind of like more specialized models for different domains and not necessarily for the domains that are presenting the biggest risks. You know, I don't think it's automatic that you build a more powerful model that it's more dangerous for cybersecurity, for example, you could deal with a more powerful model that is not more dangerous for cybersecurity, for example, if you don't train it on cybersecurity, which really people are not really talking about.

8:03Why are we not talking about that rather than talking about, you know, removing the ability to release or putting out like safeguards after the fact that we know are not really working because everyone can jailbreak them. So I think I wouldn't be totally surprised if the open source community, just because it's structurally very differently set up than the big labs, are actually taking different directions that keeps it kind of like safer and never really requires the kind of regulation that you need in kind of like a closed source AI labs. Well, is this not also kind of an argument against the capability of open source AI research?

8:44I think so because, you know, it solves different problems. Like I sometimes take the example of, you know, local models, right? Local intelligence, you know, being able to be on the flight, in airplane mode without network, and still be able to get intelligence. You can only get that with open source, right? Like you can't get that with API. There's just like literally no way to do that. So I think it's just different layers of the stack, right? And actually open source is on top of closed source. A lot of the closed source is using open source models and he's using open source infrastructure.

9:18And it's all different things. The analogy is like, you know, open source maybe is the engine and the API is the car, right? And obviously the engine is never going to be like a Ferrari, but, you know, that's what kind of like powers the Ferrari. So I think that's more like the way we approach it. And also, you know, being less good at bad things, doesn't mean that you can't be better at good things. Maybe, you know, open source is better at, you know, solving people's problems. Maybe it's better at, you know, kind of like helping, you know, do stuff really, really, really important. But it's worse at, you know, creating cybersecurity attacks.

10:09That would be kind of like the ideal case. people right now are talking about frontier as kind of like this general thing the reality is that the frontier is kind of like jagged between kind of like different tasks different domains right this one model is going to be better at some things and it's going to be worse at other things i think that's that's more kind of like how we should approach it yeah um does it make sense no yeah this totally makes sense to me so you guys just crossed 100 million dollars in arr right So I'm curious as like, what do you think this means for like, like the business model of open source?

10:45Obviously a lot of companies are doing much more revenue than we do in AI these days. You know, it hasn't really been our priority to optimize for monetization and for revenue, given what we're building, which is more kind of like a usage-based platform to reach kind of like harmony and empower as many AI builders as possible. But at this small scale, I think it shows that there's a business model for open source, there's a business model for open source platform. We kind of knew it, right? Because there's been GitHub before and there's been kind of like a bunch of open source successful companies.

11:23But I guess it's a validation of that. And we've seen, I mean, for the past few weeks, we've seen quite a lot of growth in terms of interest and adoption of not only open source models, but also local models. And so, you know, that also speaks a little bit to that. Yeah, what are some of the specific use cases that like people are using local models for? So local models are kind of like kind of free, right? Because they're running on your phone or on your laptop. And so you don't even, you don't really have to pay for them. So they're much cheaper. They're much more privacy kind of like preserving by design because you don't have to send your data to an API, right?

12:13Your data stays on your phone. And so we see people using it a lot for the things when it matters the most. So like, for example, if you want to talk about your private health and you don't want to share that with someone else. If you want to share some of your private company data and you don't want to share it externally to an API provider. Or if you want to run really, really heavy workloads, for example, agentic workloads and really have something that runs 24-7, then doing it on your laptop or like on the Mac Mini or kind of like a local hardware makes it much more sustainable. So that would be kind of like the use cases.

12:58We have this library called Lama CPP, which is the most used runtime for local AI workloads that people are using a lot. And they're using GPT-OSS, they're using Gwenn, JMA4, like all these models locally on their laptop. Yeah, for sure, for sure. So going back to open models, you can imagine that the government will want to restrict open models because a lot of them come from China. maybe not restrict them in a strict legal way, but maybe in like an export-related way. So do you think that might happen? And if so, what would that mean for Hugging Face? Yeah, I mean, like it's open waves are fundamentally different than an API, right?

13:45The way you can restrict it is very different. So for example, you know, if you remove an open wave from Hugging Face, then it's still going to be on Modelscope, for example, which is like the Chinese equivalent or it's going to be on torrent platforms. So restriction looks very, very different, I think, for open source than for APIs. You can't really block because it's open. So almost by definition, there's going to be some ways to access them. And also, provenance for open ways doesn't really matter as much because it's open. the people who are sharing it kind of like give up the control on it and give up kind of like the ability to influence you.

14:34So to me, it doesn't matter so much where open rates are coming from. It's a different game, for example, for APIs to run the inference because if you're using an API provider or a cloud from China, obviously you're sending your data. And also they could cut your access or bias your access. That's a much, much bigger problem. But for open weights and open source, it doesn't really matter where it comes from because it's kind of like you get all the control, you get all the transparency. There's no way to kind of like trick you, bias you, manipulate you, remove your access. So I think for open source, like the provenance doesn't matter as much.

15:19Yeah, I'm curious, your thoughts on just like the US government sort of like restricting the release of like GPT 4.6. Do you think that comes from like them knowing the stakes or not knowing the stakes? Like, do you think they're well informed on this matter? Or they just like know that they don't know and that's why they're taking these measures? It's a good question. I can't talk for them. I do think there's a lot of interesting learning and progress to be made everywhere, not just at the USG, but really everywhere on evaluating models, evaluating risks for models. I don't think we have really good benchmark for this, and that's a big problem.

16:01In general, ultimately, I hope we'll have more transparency. There's this agency called Casey that is amazing. I think they're doing an amazing job, and they're building up this capability to really evaluate and work on benchmark and things like that. And I'm really excited for them to take a little bit more of the workload there and kind of like take a very scientific approach to evaluating these models. And I think when they will, it's going to be really good for the Shields. Yeah, we definitely want to talk to people from KC soon. It's going to be really tough, I can't lie. We'll try. We'll try.

16:44Oh, also yesterday I was talking to Andrew Trask from DeepMind, and he had like a very interesting viewpoint that he, like there's a model on Open Router called Open Fusion, I think, and it's this like fusion model of basically a bunch of different models, and that like had a lot of advanced capabilities and like surpassed like inefficiency in a lot of ways. So do you think we're going to see more of that? I think so, yeah. I think what we're seeing right now is that a lot of people, companies are realizing that it's too dangerous, it's too risky, it doesn't make any sense to rely exclusively on one model.

17:22Why? Because this model can be taken away, this model can be biased, this model can refuse or tell you the wrong things. right that's also what we've seen before right with Fable 5 before it was taken out right is that there was some domain where it was intentionally by design kind of like telling you the wrong things right to confuse you and so I think people are realizing that that we need to rely on a multitude of models right and so I think that's driving to this outcome of doing more routing. There was an interesting study from Stanford published last year that was showing that 70 % of the queries that people ask to chat GPT could be accurately answered locally on your laptop.

18:20For free. Most of the questions you ask or most of the AI workloads that people do today with frontier models could be done by models that are cheaper, faster, more customizable, more controllable, right? And they don't do it because frankly, it's a pain to take the model picker and be like, okay, this one I'm going to go for like a cheaper one because, you know, so you're subsidized so you don't have to care because you have your subscription so you direct everything. It's like directing everything to Einstein, right? It's like, hey, Einstein, what's Einstein? What's the weather today? You know, in normal life, you would be like, fuck you, I'm not answering your silly question.

19:05But because it's AI and subsidized by the AI labs, all the questions are getting routed to Einstein versus in an ideal world, you can have different people, different models that are more specialized and better at answering your questions in different domains. So that's kind of like, yeah, what we're seeing and the way to route instead of giving you the model picker, I think it's a very, very smart option and a better one. Lovable is starting to do that too, right? Like doing the routing under the hood. And I think it will, it's possible that it's going to redistribute a lot of the value capture from frontier models, which have been the case now, right?

19:47Like majority of the revenue capture was on frontier models to a more like long tail of models, which in my opinion makes much more sense. It's like AI maturing, right? Like we were in the first phase of AI where it's very simple, very simplistic. Everyone using just one giant intake model behind proprietary APIs. Now we're moving to the second phase of the AI field more maturing and using several models, using open source, having control, building themselves. I'm quite excited about it. Yeah. So another big news story of yesterday was Anthropic accused Alibaba of doing distillation attacks, which is, you know, there's two perspectives on this.

20:31One is like, this is like, these are these evil people who are like stealing the capabilities of our models, violating our terms of service, like fraudulently accessing our product. And the other is like, what do you mean? They're creating accounts and they're paying for tokens. And, you know, you can't accuse people of stealing when you stole the entire Internet. So which one of these two positions are you closer to? Well, I mean, I think distillation is a very common practice that everyone is using. I wouldn't be surprised if Entropic used distillation in the past for some of their models, for some of their specialized models using kind of like someone else who's better.

21:07For example, when OpenAI was better at coding, like you use this model to kind of like help you a little bit in the training of your coding model. it's something that everyone uses but that is not you know the main reason for success like if you suck you suck with or without distillation it's just kind of like a little bit like accelerating thing but it's not what makes you good or bad at training models so if you stop distillation tomorrow the Chinese labs won't like go down and disappear because it's still going to be good it's not really going to change the game and you know The only point that I'm a little bit biased towards is if there was big competition problems, where it's like, oh, it's really unfair, it's biasing competition.

22:00But it's hard for me to accept this one because frankly, I mean, Entropic OpenAI, they've been the fastest growing companies in the world. They've become overnight trillion dollar companies. And so I don't think they have competition problems. It's hard for me to say like, oh, poor Entropic, poor OpenAI, you're getting unfairly competed with when you're like the fastest growing company in the world. Competition has been okay for them. If anything, I think they need more competition than less competition. Because we're heading toward a world where like a few companies are completely dominating, concentrating all power, all capabilities, all wealth.

22:45That's much more dangerous than maybe losing a couple of billion dollars of revenue. Yeah, totally. It's just hard to empathize and think that this is an important problem. I think there are many, many more, much more important problems than that in the world of AI right now. Sure. So since the last time we talked, there have been two big pieces written about Europe. There's this essay, Europe 2031, which is basically AI 2027, but for Europe. Like basically Europe will slide into a relevance if they don't lock in on AI right now. And then the other was Anton Leisch, who's a policy writer, wrote this piece on subset called The Moonshot, which basically explained how if Europe wanted to do so, they could build a frontier lab.

23:42Do you think that it's possible for Europe to do this at this point? Could they build a frontier lab if they really tried? I think so, yeah. They have a lot of really great resources. They have great people. You already have some great labs, right? Black Forest Lab, Mistral, all these people are doing amazingly and arguably they're at the frontier. year. They have amazing energy. Obviously, France, for example, nuclear energy, very abundant. So they could really use a lot of clean energy for AI. So yeah, I think they could. It's just a matter of focusing the energies towards that, building an ecosystem.

24:29It never, sometimes we build the stories of companies emerging out of the blue by their sheer power. But the reality is it's more an ecosystem. And you see that from OpenAI, the T of transformers, obviously it's coming from Google, that open source transformers. And so it's more of a matter of, in my opinion, fostering an ecosystem of open research, open source AI, which is what happened in the US. Right. And kind of like fostering that progressively to bring more and more companies, organizations closer to the frontier. Yeah, totally. I'm curious, like, since you run such a large platform, like, what are younger people doing with AI?

25:22Are younger people actually becoming very, very proficient in like AI native? Or like, how do you see this pattern of behavior? yeah yeah we see them a lot trying it's almost kind of like I feel like young people went through the first phase of being users of AI really quick and now a lot of them I think want to be builders yeah so we see a lot of yeah very young people going under a new phase getting models and you know building products themselves or optimizing training models themselves you know building data sets themselves. So I see a lot of like building appetites in AI for young people in a lot of different domains.

26:09Not necessarily in the most talked about domains, but also in a lot of like very you know topics that are really not talked about like climate change, you know, biology, chemistry, you know, really kind of like social media, kind of like a lot of topics that we don't really talk about that I feel like are closer to everyone's interest. And I see a lot of young people working on these things. It's a good white pill to end on. That is. Yeah. Well, thank you so much, Clem. This was so great. Thank you, Clem. Thanks for having me.

From the publisher

As governments weigh new restrictions on frontier AI models, one question is becoming increasingly important: what role should open source play in the future of artificial intelligence?

Theo Jaffee and Sofia Puccini speak with Hugging Face CEO Clément Delangue about AI regulation, open source safety, model routing, and why he believes competition—not consolidation—is essential for the industry's future.

They discuss GPT-5, government oversight of frontier models, Hugging Face surpassing $100 million in annual recurring revenue, local AI, China's open-source ecosystem, Europe's AI ambitions, and why routing workloads across specialized models could fundamentally reshape where value is created in AI.
