Introduction
In the world of artificial intelligence, few organizations capture the imagination quite like OpenAI. Known for its groundbreaking advancements in AI technology, OpenAI has become a focal point for both media attention and public discourse. Recently, however, the organization has found itself under scrutiny, not just for its technological achievements but also for its internal culture and work environment. The conversation reached a new level when former OpenAI employee Calvin French-Owen published a reflective account of his time at the organization. His story provides a rare glimpse into the daily grind at OpenAI, including the intense work hours and the rapid development cycles that have come to define the company.
Calvin French-Owen, an experienced entrepreneur and engineer, joined OpenAI in May 2024. With a background in computer science from MIT and a history of co-founding the successful customer data platform Segment, French-Owen’s insights carry significant weight. His article sheds light on what it’s really like to work at OpenAI, especially during the development of Codex, an AI-powered programming assistant. This article delves into French-Owen’s experiences, the broader context of OpenAI’s work culture, and what this means for the future of the organization and its employees.
The Man Behind the Account
Before we dive into the specifics of French-Owen’s revelations, it’s important to understand who he is and why his account matters. A graduate of MIT’s computer science program, French-Owen co-founded Segment before it was acquired by Twilio for a staggering $32 billion. His credentials are impeccable, and his experience in the tech industry is extensive. After brief stints at Y Combinator and other organizations, French-Owen joined OpenAI in May 2024, where he worked as an engineer on the Codex project.
Codex is one of OpenAI’s most notable achievements, designed to assist developers in writing code more efficiently. French-Owen’s role in its development provides him with unique insights into both the technical and cultural aspects of working at OpenAI. After leaving the company in June 2025, he penned a detailed account of his experiences, which has since sparked widespread discussion about the organization’s work environment.
The Development of Codex: A Seven-Week Sprint
One of the most striking revelations from French-Owen’s account is the intense pace at which OpenAI operates. He describes the development of Codex as a seven-week sprint, highlighting the breakneck speed at which engineers were expected to work. This rapid development cycle is a testament to the high-pressure environment that exists within OpenAI.
French-Owen explains that the team working on Codex often found themselves burning the midnight oil, with many engineers staying at the office until the early hours of the morning. This level of dedication is not uncommon in the tech industry, but the extent of the hours and the intensity of the work at OpenAI are particularly noteworthy. The pressure to deliver results in such a short timeframe inevitably led to burnout and high-stress levels among employees.
The seven-week development cycle for Codex also underscores the high expectations placed on OpenAI engineers. The organization is at the forefront of AI research and development, and the need to stay ahead of the competition means that employees are often pushed to their limits. While this approach has resulted in groundbreaking innovations, it also raises questions about the long-term sustainability of such a work culture.
The Daily Grind: What It’s Really Like to Work at OpenAI
French-Owen’s account provides a detailed look at the daily life of an OpenAI employee. He describes a work environment where the boundaries between work and personal life are often blurred. Engineers are expected to be constantly available, and the pressure to make progress on projects can be overwhelming.
One of the most significant challenges French-Owen highlights is the lack of work-life balance. He notes that employees frequently work late into the night, sacrificing personal time and relationships for the sake of the project. This level of commitment is not just encouraged but often seen as a requirement for success at OpenAI.
The high-pressure environment also extends to the organization’s management style. French-Owen describes a culture where employees are given a significant amount of autonomy but are also held to extremely high standards. The combination of autonomy and accountability can be both empowering and stressful, particularly when the stakes are as high as they are at OpenAI.
