🔍Deep Dive Analysis
Andrej Karpathy's journey in artificial intelligence began with his academic pursuits, culminating in a PhD from Stanford University in 2015, where he focused on the intersection of natural language processing and computer vision. During his time at Stanford, he was the architect and primary instructor of CS231n: Convolutional Neural Networks for Visual Recognition, which became one of the university's largest and most popular courses.
In 2015, Karpathy became a founding member and research scientist at OpenAI, an organization dedicated to ensuring that artificial general intelligence benefits all of humanity. His initial tenure at OpenAI lasted until June 2017, when he transitioned to Tesla, Inc.. At Tesla, Karpathy took on the role of Director of Artificial Intelligence, reporting directly to Elon Musk. He was instrumental in leading the computer vision team for Tesla Autopilot, overseeing in-house data labeling, neural network training, and deployment on Tesla's custom inference chip. His work was crucial in advancing Tesla's self-driving capabilities, moving Autopilot from lane-keeping to city streets.
Karpathy announced his departure from Tesla in July 2022, following a sabbatical. While the official reason was a desire to unwind, some analysts speculated that his departure might have been related to Tesla's 'vision-only' approach to self-driving and the subsequent removal of ultrasonic sensors, which led to temporary limitations in features for new cars. After leaving Tesla, Karpathy dedicated time to creating educational YouTube videos on building artificial neural networks.
In February 2023, Karpathy announced his return to OpenAI, expressing inspiration by their work and excitement for future potential. During this second stint, he built a new team focused on midtraining and synthetic data generation. However, his return was relatively short-lived, as an OpenAI spokesperson confirmed his departure again on February 13, 2024.
Following his second departure from OpenAI, Karpathy continued his focus on AI education. In July 2024, he announced the founding of Eureka Labs, an AI education company with a broader educational effort, including the "Zero to Hero" series on LLM fundamentals and the LLM101n course. He also gained recognition for coining the term "vibe coding" in February 2025 and for publishing an LLM Wiki GitHub Gist in early April 2026, which describes an architecture for a personal knowledge base using AI agents.
CURRENT STATUS as of 2026-05-19: On May 19, 2026, Andrej Karpathy announced on his X account that he has joined Anthropic, a prominent AI safety-focused company known for its Claude family of large language models. He expressed excitement to return to research and development, stating that the next few years at the frontier of LLMs will be "especially formative." Karpathy will be working on Anthropic's pretraining team, responsible for large-scale testing of Claude, and has indicated his intention to resume his educational work in the future.
