uh yeah, I work on a bunch of the thinking models at OpenAI.
Um and like recently I've been sort of focused on doing search related stuff.
But yeah, just a post training researcher at OpenAI.
Yeah, it's been wild.
And like you know, 4.1 was a non-thinking model.
And then since then I, you know, we sort of switched into doing Is that your last?
Was your last?
Uh no, we're still we still are releasing non thinking models.
Um, but that one was the one that we did that was like API specific non thinking.
Um so you know, focus has shifted a little.
Um, so previously before opening, I was doing like pre-training data curation stuff.
And I think what I was seeing from like the news and looking at papers is like, oh, it seems like a lot of not pre-training is dead, but I was like, oh, there's gonna be so much interesting stuff in post-training.
And at that point, I was like, I really wanna like make some contributions there.
And I mean, it's not even necessarily that like pre-training was dead, but it
is definitely changing and like, you know, do I wanna make compute efficiency wins of like three percent or do I wanna like change the behavior by forty percent?
And honestly it just seemed more more exciting to go to post training.
And many late nights later.
I that's definitely true.
Yeah, definitely.
I think like uh for example, the number of moving parts in an RL run is just a lot higher.
