As OpenAI’s present VP of Product, Peter runs the corporate’s product and commercialization efforts. Earlier than that, he performed an important position in researching and creating certainly one of OpenAI’s most well-known merchandise: GPT-3 API.
However regardless of being a founding member of OpenAI’s Robotics Analysis workforce. Peter truly had reservations concerning robotics. He felt its normal procedures have been too sluggish or too clunky to effectively meet actual world calls for.
What modified his thoughts?
His Educational Endeavors
For the document, Peter was at all times taken with machine studying and synthetic intelligence.
His curiosity was piqued in highschool, when he learn a ebook about AI. That preliminary spark inspired him to proceed exploring comparable disciplines, ultimately resulting in an undergraduate diploma in physics. He then pivoted to neuroscience within the California Institute of Know-how, believing this was a sensible strategy to pursuing his ardour.
The argument was sound–however it simply wasn’t meant to be.
Micro-Implants for Mice
Peter’s most vivid expertise in neuroscience concerned him sitting for hours at a time in a basement, constructing micro-implants meant to be inserted in rat’s brains.
Whereas this scene definitely wouldn’t be amiss in a geeky sci-fi tv collection, Peter grew sick of it in lower than a yr. The method, he mentioned, was lonely. The micro-implants took three months to construct. Then got here the precise surgical procedure wanted to insert the implant within the rat.
And if, at any level in the course of the mission, an error occurred, it was again to sq. one.
Ultimately, Peter realized that neuroscience wasn’t the profession for him. He felt that if he continued down this path, it will take him without end to get to grad college. Plus, he wished to focus extra on robotics. So he shifted to get a PhD in Computation and Neural Methods.
A Comparable Downside
Sadly, robotics had an analogous downside. It took means too lengthy to provide helpful and usable outcomes. The method of designing the robotic, constructing the robotic, after which ultimately programming the robotic to ensure it labored as meant was, as Peter places it, most likely three quarters of his PhD. That wasn’t together with the experiments they must run on the finish, too.
So he took a extra particular, specialised strategy this time. He determined to choose only one side of the method and see the place that might take him.
This allowed him to give attention to laptop imaginative and prescient–a course of that might jump-start his work (and subsequent breakthroughs) with picture group and OCR, or Optical Character Recognition.
Animals & Anchovi Labs
Peter’s work with laptop imaginative and prescient and OCR engines impressed him to create his personal startup, Anchovi Labs. Their fundamental product was an app that tracked photographs of animals utilizing laptop imaginative and prescient.
It was, for its time, an revolutionary idea. But it surely additionally wasn’t possible. Prices have been too excessive, demand was too low, and there simply wasn’t sufficient market curiosity to recoup sources.
However he wasn’t deterred. Peter and his workforce shifted their focus to creating an app that used laptop imaginative and prescient (nonetheless!) to independently arrange photographs. Thisenterprise caught the eye of–and was later acquired by–Dropbox; one of many world’s largest file internet hosting and cloud storage service suppliers.
As its creator, Peter adopted swimsuit.
Coping with the Darkish Matter of Dropbox
When Peter first joined Dropbox in 2012, one of many greatest challenges he confronted was coping with the sheer quantity of photographs saved within the server. There have been so many photographs (billions, he remembers) taking over a lot area.
And so they have been helpful to utterly nobody.
They have been, in accordance with Peter, mainly like darkish matter. And he was decided to do one thing about them. So he began easy; indexing the photographs in order that customers may filter them by normal information like date or location.
As soon as the recordsdata have been organized, he then centered on serving to customers extract data from them.
This characteristic was most helpful for enterprise paperwork. Somewhat than scan the paperwork in query, most Dropbox customers as a substitute took photos of them–to protect them, to have their very own copy, to have a digital backup, and many others. However since photos aren’t editable textual content recordsdata, organizing them and retrieving information from them was troublesome.
So Peter and his workforce created a program that allowed customers to retrieve solely photographs of textual content paperwork (private photographs, household photographs, sketches, and the like would not be introduced up). Then, this similar program would extract the info from the image utilizing OCR.
However as a substitute of counting on current OCR engines, they determined to construct their very own from scratch utilizing deep studying algorithms. They created benchmarks primarily based on one of the best OCR methods at the moment, like Google and ABBYY.
“In three months, we had crushed all the general public dataset benchmarks,” Peter says in an interview with Weights & Biases. “That was simply mind-blowing to me. That’s the stuff that might have taken a lot longer [to build] earlier than.”
On Robots & OpenAI
In 2014, Peter based Dropbox’s Machine Studying Crew. They labored with different departments within the firm to “establish, develop, and ship machine studying options” so they might enhance and/or optimize current merchandise.
He left Dropbox two years later to change into a founding member of the Robotics Analysis Effort at OpenAI.
Peter’s curiosity in robotics by no means actually pale. He’d merely set it apart in favor of methods and processes that didn’t take fairly as lengthy and weren’t fairly as clunky. His success in laptop imaginative and prescient validated this resolution as effectively.
However when the workforce at OpenAI began entertaining the potential of AI and AGI (synthetic normal intelligence), Peter’s curiosity was rekindled. He noticed this as a possibility to give attention to problem-solving relatively than publishing. Individuals have been getting outcomes with deep studying and deep reinforcement studying, so he turned his consideration there. And he realized quickly sufficient that this was a sensible and promising reply to his robotics downside.

Peter’s Tasks & Present Profession
Because the Analysis Lead at OpenAI, Peter had the chance to work on quite a lot of robotics initiatives. Among the extra notable ones embody:
Coaching a robotic hand to unravel a Rubik’s Dice
Robotic Imitation Studying (the place their robotic ultimately managed to beat the Dota 2 World Champion)
OpenAI Distant Rendering Backend
Studying Dexterity
After that, he grew to become the Product, Engineering & Analysis Lead for the early improvement levels of OpenAI GPT-3 API. He was hands-on the entire time, main his workforce by means of the grueling course of of making one thing that had actually by no means been accomplished earlier than.
Fortunately, Peter has implausible management and significant considering abilities.
He acknowledged that OpenAI had formidable objectives. However he additionally believed that “huge issues” could possibly be achieved with sufficient workforce effort. So relatively than mood these objectives with actuality, he as a substitute rose to the problem.
And we ought to be grateful that he did. In any other case, who is aware of what would have occurred to ChatGPT.
Peter’s story is much from over however it already serves as encouragement and inspiration for college students who share his ardour. His journey is proof that you simply don’t have to get it proper the primary (or second, and even third!) time. With sufficient persistence and perseverance, you’ll find yourself on the trail you have been meant to take all alongside.
