Behind the Curtain: A Former OpenAI Engineer Shares Insights into Working at a Leading AI Company

  Recently, Calvin French-Owen, an engineer who significantly contributed to OpenAI’s development efforts, announced his departure after a year at the company. In his detailed blog post, he offered rare insights into what it’s really like to work at one of the most influential AI organizations of our time, shedding light on the company’s culture, rapid growth, and internal challenges.

Rapid Growth and Organizational Challenge

OpenAI’s explosive growth became evident during French-Owen’s tenure, increasing from approximately 1,000 to over 3,000 employees within a year. This expansion correlates directly with the surge in popularity of ChatGPT, which surpassed 500 million active users by March and continues to grow rapidly.Such rapid scaling, while impressive, introduces inevitable organizational complexities. French-Owen describes a landscape of “chaos,” where communication channels, reporting structures, and product deployment processes struggle to keep pace with growth. Technical teams face duplicated efforts, as multiple groups independently develop similar libraries and tools. For example, he noted seeing multiple implementations of queue management and agent loops across teams, highlighting the need for more centralized coordination.

Despite these growing pains, the company fosters an environment that encourages agility. Employees retain significant autonomy, allowing innovation to flourish even as the organization expands. This “startup-like” culture helps drive rapid development but also demands continuous improvement in operational processes.

Maintaining Startup Spirit at Scale

One of the most striking insights from French-Owen’s account is that OpenAI still operates with a startup ethos. Teams are empowered to act quickly, often with minimal red tape, fostering innovation and experimentation. However, this freedom can lead to inefficiencies, such as overlapping efforts or inconsistent coding practices.

He describes how, despite the large scale, engineering efforts remain intense and fast-paced. For example, his team built and launched Codex — an AI-powered coding assistant — in just seven weeks. The project’s launch was remarkable not only because of its speed but also because of the immediate user response: thousands of users jumped onto the product immediately, a testament to the power of ChatGPT’s ecosystem.This fast-paced environment, while rewarding, demands resilience and adaptability from employees. It also underscores the importance of balancing speed with long-term strategic planning to avoid the pitfalls of rapid growth.

The Bigger Picture: AI Safety and External Scrutiny

An important aspect often misunderstood is OpenAI's approach to safety. Many critics argue that the company might not be as cautious as necessary, but French-Owen emphasizes the opposite. Internally, the focus revolves around practical safety concerns like hate speech, abuse, political bias, and prompt injections.

Moreover, he notes that there is a dedicated effort to long-term safety, with researchers actively exploring existential risks. The significant real-world applications of models—used for everything from medical advice to mental health support—make responsibility and safety central to OpenAI’s mission.

His account also highlights an environment of high external scrutiny, where secrecy and vigilance are routine. The company closely monitors discussions on social media platforms like X (formerly Twitter), quickly responding to viral posts or leaks, which he humorously describes as “run on Twitter vibes.

French-Owen’s insights shed light on a company that, despite its size and rapid growth, still retains a startup spirit. Innovation, agility, and responsibility define its culture, even amidst the chaos. For industry leaders and educators, understanding this delicate balance is vital as AI continues to evolve and influence society.
