Chen: OpenAI's three-year goal is models conducting end-to-end research
“When we look at our kind of three-year roadmap, right the end goal that we want to reach is one where You know, the models are just doing end-to-end research, and I think a part of that problem is just being able to have the model come up with good taste.”
Chen: Meta poaching has calmed down and OpenAI came out on top
“I think that met us calmed down a little bit. I think we came out on top”
Mark Chen: AI models are producing 'Move 37' breakthroughs in math and coding
“There's move-thirty-sevens in, in math. There's in computer science and coding. I think even, yeah, just, it feels like a lot of people woke up at the start of this year and were like, man, agents are working in my profession. And you know, they're essentially…”
OpenAI's Chen: AI models already discover novel theorems and advance sciences
“The initial direction we took was you should move it to real world research, right? And we've seen that the models, they've gotten a lot better at just kind of discovering novel theorems and pushing the frontiers of hard sciences. Even today, right, that's no …”
Mark Chen: AI scaling laws will continue to hold
“And so I think it's just more and more of the same, right? Like more careful research engineering, more careful data engineering, more careful scaling, and it always unlocks that next ability to scale further. So I mean, it's held for You know, almost 10 order…”
Chen: OpenAI favors unifying modalities in as few architectures as possible
“For a research lab, I think there are a lot of advantages for it to being under one. So you just have to maintain one infrastructure stack, for instance. I think the cost to, like, maintaining and scaling many infrastructure stacks at once I think that's somet…”
Chen: Pre-training is not dead and remains underrated in AI research
“Well, I think if you still have a pre-training is dead view of the world I think pre-training is definitely yeah, yeah, not, not dead. It's underrated.”
Chen: OpenAI has internal models matching Gemini 3 and better successors coming
“Just looking purely at the benchmarks, you know, we actually felt quite confident you know, we have models internally that perform at the level of Gemini three, and we're pretty confident that we will release them soon, and we can release successor models that…”
Chen: GPT-5 Pro automates tasks that take physics students months
“And you know, we see physicists, mathematicians kind of repeating this experience over and over where they're trying GPT-Five Pro and saying, wow, this is something that the, you know, previous version of the models couldn't do. And it is a little bit of a lig…”
Chen: AI reasoning only emerges at large scale requiring massive compute
“When you look at reasoning you just don't see that happen at small scale, right? There's like a certain scale at which it starts becoming signal bearing and that requires you to have resources, right?”
Chen: GPT-4.5 performance jump matches leap from GPT-3.5 to GPT-4
“It signifies an order of magnitude improvement over the last models, kind of commensurate with the jump from 3.5 to four.”
Chen: AI models cannot learn reasoning from scratch without pre-trained knowledge
“You need knowledge in order to build reasoning on top of it.
Right.
a model can't kind of go in blind and just learn reasoning from scratch.
So we find these two paradigms to be fairly complementary and we think, you know, they have feedback loops on each oth…”
Chen: GPT-4.5 scaling returns remain consistent with OpenAI's prior projections
“You know, we are seeing the same returns, and I do want to stress that GPT-D 4.5 is that next point on this unsupervised learning paradigm, and, you know, we're very rigorous about how we do this. We make projections based on all the models we've trained befor…”
Chen: GPT-4.5 hits expected benchmark progression consistent with OpenAI's trajectory
“Well, I really don't think that the accurate characterization is that it doesn't hit the benchmarks that, that we expect it to. So when you look at kind of the development of three to 3.5 to four to 4.5 this does hit the benchmarks that we expect.”
Mark Chen: A PhD is not necessary to excel in AI research
“There are a lot of researchers who just started out without formal training in machine learning or AI research. We've very much believed in training people up to do this. I think the real hard thing is the ability to creatively solve problems and think outside…”
Jakob Pachocki and Ilya Sutskever overcame internal inertia to build OpenAI o1
“Even at a company like OpenAI, you would have people ask naturally, why do something when you have a machine that works? And fundamentally, you know, it's to the credit of, you know, Jakob, Ilya, many of the people who really had conviction and vision in this …”
OpenAI's Mark Chen: AI is in an evals crisis with saturated benchmarks
“So I think beyond that, the other scary thing in the field is the number of canonical gold standard benchmarks is low. And we really are kind of in an evals crisis, right? Where all the really great evals that we all know, like growing up, like taking the SAT …”
Chen: Eval teams and model optimization teams must remain separate
“Yeah, I think there's a kind of interesting philosophy of separate the teams that are creating the evals from the teams that are optimizing the models themselves, because that way you don't, like, co-incentivize them, right? Like, the way the evals theme can w…”
Chen: 2025 will be the year of autonomous AI agents
“We see 25 as this year of agents, right? We think of it as a year where models are going to do a lot more autonomous work. You can let them Kind of be unsupervised for much longer periods of time.”
Chen: Frontier AI models consistently score over 90% on AIME
“I think one clear example here is the Amy, like probably the hardest auto gradable, like human math eval, at least in the US. And yeah, the models are consistently getting like 90 plus percent on these.”
Chen: AI reasoning is the key mechanism to make agents reliable
“And I think the reason why we care so much about reasoning is because I think that's the path that we get reliable agents through.”
Chen: Focus on reasoning models caused the longer gap before GPT-4.5
“Why there seems to be, you know, a little bit bigger of a gap in release time between four and 4.5, we've been really largely focused on developing the reasoning parallel paradigm as well.”
Chen: GPT-5 could combine unsupervised scaling with reasoning paradigms
“And so I think, like GPT-V really could be the culmination of a lot of these things coming together.”
Chen: Users prefer GPT-4.5 over GPT-4o by 60% to 70% margins
“When we look at, kind of, comparisons against GPT-FORO you'll see that everyday use cases, people prefer, you know, by a margin of 60% for actually productivity and knowledge work against GPT-FORO, there's almost like a 70% preference rate.”
