Transcript context
…Yeah. First for open source in general, I think it’s really something which looks to the January of the company. I think we started it per once, is we so we have open sourcing with, since the beginning and even before this. So before this, so me and Tim were at Meta, we released LA and I think what was really nice. To see that before this, for most researchers like universities, it was impossible to work on elements. There was no alien outside. And if you look at many of the techniques that were developed after, for instance, was open source all this post-training approaches like even DPOD, like preference optimization, all of this were done by people that had access to this portal. And it’ll have been impossible to do without this. So it’s really making sense, move faster. So we really want to contribute to this ecosystem. I think like the deep and also like very lot of impact. All these papers that are I think in the open source community are really helping the science community as a whole to move faster. So we want contribute to this ecosystem. That’s why we’re releasing very detailed technical reports. So ma trial and our first reason model, and ation, lot of results, things that work, things that did not work as well. Think helpful on the, yeah, so for the audio model also to share a lot of details, share of them for real time model. And the, yeah, so we really want to continue this, basically belong to this community of people who share science. I think we really don’t want to be, leading in a world where the smartest model, the best models are only behind, close doors. Only accessible to a shoe companies that we, as a power to decide we can use them on it. I think it’s a scary future. We don’t want to live in, we really want this model to be accessible to anyone that want. Intelligence to be used unaccessible by anyone who can use it. So yeah, so that’s why we are pushing this mission and source model. Yeah. So not, so yeah, no strategy. So it’s open source, not the first model, so not the best on the Yeah. y anyone who can use it. So yeah, so that’s why we are pushing this mission and source model. Yeah. So not, so yeah, no strategy. So it’s open source, not the first model, so not the best on the Yeah. LIN trial I think is also one step into this direction. So it’s yeah, a bit different than what we are usually releasing. But we have a small team internally [00:36:00] working on them. Formal proofing, formal math. So I think a subject we care about in general and we were working on reasoning. I think we started too early before doing reasoning without LMD is very hard, especially when you work with formal systems because the amount of data you have is negligible. It’s addressable community of people writing like formal proofs. But the reason why we like it is because I think there is if you look at what people are doing with reasoning, is there, the problems that you can use. Are usually going to be problems where you can verify the output. So for instance, all this ai ME problem where the solution is a number between 100, like a thousand. So you can verify, compare this with a reference or it’s an expression. You can actually compare the output expression generic with the reference. But there are many, most of them have problem and most of the reason problem. There is no like way to easily verify the solution. If the question is show that F is continuous, cannot compare in the reference, right? If it’s a probe that this is true or probes is properties, there is no way to. You cannot act, simply verify the correctness of your proof. So it’s hard to apply the, there is no referable reward here. So what you could provide is of course, like a judge and judge that will look at your proof. But it’s very hard and it’s very, you could do certain, some reward hacking happening there. So it’s difficult. You could provide like a reference proof, but then there are also many ways to prove the same thing. So if the model says give negative reward because it’s a different poop, maybe it was still digit proof, just different. So it’s not going to work well. What’s nice with lean and with formal probing is that you don’t have to worry about this whatsoever. We just, they’re all function is largely compiles in lean is functionally the same. Exactly.…
