Names like Ilya Sutskever and Pieter Abbeel usually show up in the same sentence when people talk about the "Mount Rushmore" of modern AI. If you've spent any time scrolling through Reddit threads or X (formerly Twitter) lately, you’ve probably seen the rumor: that Ilya was actually Abbeel’s student.
It makes sense on paper. Both are giants. Both were at the center of the OpenAI explosion. But the reality is a lot more nuanced than a simple teacher-student relationship.
Honestly, the "student" label is a bit of a misnomer, or at least a massive oversimplification of how the AI elite actually grew up together.

The Toronto vs. Berkeley Divide
To understand the connection, you have to look at where these guys actually got their degrees. Ilya Sutskever is, and always will be, the star pupil of Geoffrey Hinton at the University of Toronto. That’s where the real "student" magic happened. Ilya was the guy who helped build AlexNet, the 2012 breakthrough that basically told the world, "Hey, neural networks actually work."
Meanwhile, Pieter Abbeel was carving out his own kingdom at UC Berkeley.
Abbeel is the king of Robot Learning. While Ilya was focusing on the "brains" (vision and language), Abbeel was obsessed with how those brains control physical bodies. Think robots folding laundry or learning to walk through trial and error.
So, was Ilya ever Abbeel’s student in a classroom? No.
But their paths crossed in a way that’s arguably more interesting. In late 2012, after Ilya finished his PhD, he did a very brief stint as a postdoc at Stanford. His advisor there? Andrew Ng.

Here’s the kicker: Pieter Abbeel was Andrew Ng’s student years earlier.
Basically, they are "academic siblings" or "cousins" rather than teacher and student. They both come from the same legendary lineage of researchers who believed in deep learning when the rest of the world thought it was a dead end.
The OpenAI Melting Pot
The reason people get confused is that for a long time, Pieter Abbeel and Ilya Sutskever were essentially on the same team. When OpenAI launched in late 2015, Ilya was the Chief Scientist.
Pieter Abbeel joined shortly after as a research scientist, eventually taking a leave from his professor gig at Berkeley to work there full-time.
In that environment, the lines between "senior" and "junior" get blurry fast.
- They co-authored massive papers.
- They white-boarded the future of Reinforcement Learning (RL).
- They shared the same mission of building AGI.
If you look at the paper Variational Lossy Autoencoder from 2017, you’ll see both their names. They weren't teacher and student; they were peers in a high-pressure lab where everyone was trying to prevent the world from ending while simultaneously trying to invent the future.
Why the Confusion Matters
People love a good "prodigy" story. It’s easier to say "Abbeel taught Sutskever" than to explain the complex web of academic postdocs, visiting professorships, and co-founding roles.
Actually, the real "students" of Abbeel are people like John Schulman (another OpenAI co-founder) or Chelsea Finn. Those are the folks who actually sat in his lab at Berkeley and had him sign off on their dissertations.

Ilya was already a "made man" in the AI world by the time he and Abbeel were sharing office space.
The Divergence: Robotics vs. SSI
Fast forward to today, 2026. The two have gone in very different directions.
Abbeel is still the go-to guy for robotics. After leaving OpenAI to found Covariant, he recently moved to Amazon to lead their LLM and robotics efforts within their AGI org. He’s still focused on the physical—how AI interacts with the messy, real world.
Ilya? He’s gone full "Safe Superintelligence."
After the whole Sam Altman firing drama—where Ilya was famously a key player on the board before regretting it—he started SSI (Safe Superintelligence Inc.). He’s not worried about robots folding socks. He’s worried about the "ghost in the machine" becoming more powerful than humanity can handle.
Actionable Takeaways for AI Enthusiasts
If you’re trying to track these two or break into the field yourself, don't just look at the names. Look at the lineages.
- Follow the "Toronto School": If you like Ilya’s work, study the papers coming out of the University of Toronto and the Vector Institute. That’s the home of "Large Scale" thinking.
- Follow the "Berkeley School": If you’re into Abbeel, look at the BAIR (Berkeley AI Research) lab. This is where the most practical, "embodied" AI research happens.
- Check the Citations: Use Google Scholar to see who actually advised whom. Look for the "Advisors" section. You’ll see Ilya lists Hinton, while Abbeel lists Ng.
- Watch the Founders: Many of Abbeel’s actual students have founded companies like Perplexity and Ideogram. If you want to see where the next big thing is coming from, watch Abbeel’s PhD graduates, not just the famous names he worked with at OpenAI.
It’s tempting to group all the "AI Godfathers" together. But the distinction between the "vision/language" crowd (Ilya) and the "robotics/control" crowd (Abbeel) is what defines the current battle for AGI. They aren't teacher and student—they are the two different halves of the same coin.
