According to Business Today, Tworek joined OpenAI in 2019. He is listed among the authors of a paper on solving a Rubik’s Cube with a robot hand, submitted to arXiv in October of that year.⁠[1][2]

In July 2021, the paper “Evaluating Large Language Models Trained on Code,” which introduced the code language model Codex, was submitted to arXiv, with Tworek as second author. Business Today said he led the Codex research, which later became the foundation of GitHub Copilot.⁠[3][1]

According to Business Today, he became OpenAI’s vice president of research in 2022. The Decoder described him as a key contributor to building GPT-4, ChatGPT, and OpenAI’s first coding models.⁠[1][4]

OpenAI released o1-preview on September 12, 2024. In OpenAI’s published list of o1 contributors, Tworek is listed in the leadership group of “Foundational Contributors,” marked “overall.” The Decoder reported that he was part of the core group behind the o1 and o3 models and, before leaving, led the “Reasoning Models” team.⁠[5][6][4]

In early January 2026, multiple outlets reported that Tworek was leaving OpenAI after nearly seven years. According to the reports, he said he was leaving to explore types of research that are hard to do at OpenAI.⁠[4][1]

In April 2026, The Decoder reported that Tworek had launched a new AI lab, Core Automation, whose research directions include new learning algorithms beyond pre-training and reinforcement learning and architectures that scale better than transformers. The company’s website says its goal is to build the “most automated AI lab,” starting by automating research itself.⁠[7][8]
