Andrej Karpathy is a computer scientist who has a passion for training deep neural nets on large datasets. He is best known for his principal roles at Openai and Tesla and also designed and instructed the first deep learning class at Stanford University.

Let’s take a look at Karpathy’s achievements thus far.

Education and research

Karpathy studied for his Ph.D. in Computer Science at Stanford between 2011 and 2016. His thesis centered on the creation of novel recurrent and convolutional neural networks (CNN) and how they could be used in NLP and computer vision.

Scientists had been endeavoring to teach computers to see for decades, but few have come closer than Karpathy. 

He combined CNNs with other approaches to enable computers to see individual objects (such as a cat) but also the entire scene of objects and how they interacted – in other words, that the cat had brown fur, was spotted, and riding a skateboard across a hardwood floor, for instance.

In 2015, Karpathy became the primary instructor of Stanford’s first deep learning class. Titled Convolutional Neural Networks for Visual Recognition, the class has since grown to become one of the most popular AI-related courses on offer.

OpenAI

Post-university, Karpathy joined OpenAI as one of its founding research scientists. Early on, he assisted with recruiting and structuring but later worked on deep reinforcement learning and deep learning for generative models.

Among other projects, Karpathy trained a computer controlling a keyboard and mouse to accomplish various online tasks such as filling out a form. After 18 months, however, he left the company to join Tesla after reportedly being poached by fellow OpenAI founding member Elon Musk.

Tesla

Karpathy was involved in multiple AI endeavors at Tesla. Most notably, he worked on Tesla’s Autopilot, a hardware system trained on a company-developed neural network that offers advanced driver safety and convenience features.

To create this near-autonomous driving experience, Karpathy oversaw efforts to gather and label data, train the neural network, and deploy it successfully via segmentation, detection, 3D or depth estimation, and so forth. 

When Tesla expanded Autopilot to incorporate a broader range of AI, Karpathy became Senior Director of AI. 

He also worked with Musk on the “Optimus” humanoid robot which debuted at Tesla’s 2022 AI Day. The robot, which Musk claimed could be sold to the public for “probably less than $20,000”, incorporated many of the features and sensors from Autopilot.

Return to OpenAI

Karpathy announced on Twitter in February 2023 that he would be returning to OpenAI: “Like many others both in/out of AI, I am very inspired by the impact of their work and I have personally benefited greatly from it.”

Analytics India Magazine was not surprised by the move since Karpathy and OpenAI had publicly acknowledged each other’s work in a back-and-forth after ChatGPT was launched. 

Outlook Start-Up agreed, but for different reasons: “Karpathy’s focus on open-source and education aligns with the mission of OpenAI, which makes it a natural fit for him to return to the company.”

Key takeaways:

• Andrej Karpathy is a computer scientist who has a passion for training deep neural nets on large datasets. He is best known for his principal roles at OpenAI and Tesla and also designed and instructed the first deep learning class at Stanford University.
• Post-university, Karpathy joined OpenAI as one of its founding research scientists. Early on, he assisted with recruiting and structuring but later worked on deep reinforcement learning and deep learning for generative models.
• Karpathy then joined Tesla after being poached by Elon Musk. There, he worked on the Optimus humanoid robot and Tesla’s autonomous driving efforts under the banner Autopilot. Inspired by the company’s work, he then announced in February 2023 that he would be returning to OpenAI.
