Calvin French-Owen, a former technical staffer at OpenAI, has offered a candid glimpse into the company’s internal culture just three weeks after his departure. While OpenAI is widely perceived as a cutting-edge workplace driving world-changing AI breakthroughs, French-Owen paints a different picture—one of secrecy, pressure, and relentless pace. In his blog post, he described his 14-month tenure as both exhilarating and exhausting, working on the Codex project, but often feeling the weight of performance and perception.

French-Owen revealed that OpenAI’s culture placed unusual emphasis on social media “vibes”, with internal decisions and morale often influenced by online sentiment. The company’s structure allowed for fast-paced decision-making and significant autonomy, where employees could pursue ideas rapidly without bureaucratic delays. Communication relied heavily on Slack rather than email, reflecting the company’s preference for speed and informal flow—but also contributing to blurred boundaries and nonstop work.

Despite that freedom, secrecy was a defining element. Employees were often unaware of what other teams were doing, and financial transparency was minimal. One thing was crystal clear, though: GPU costs dominated budgets, highlighting the scale and expense of AI development. Reports from Reddit and other sources also echoed similar sentiments—long hours, high output, and burnout being a norm.
As they say, some personal news–
I just left @OpenAI after launching Codex. Extremely grateful to everyone there who I got the chance to work with and learn from.

This relentless pace led OpenAI to implement company-wide breaks to counter fatigue, but French-Owen’s decision to leave suggests deeper issues. He respected the mission and his team but questioned the sustainability of the work culture. His experience serves as a nuanced reflection on the trade-offs of working at one of the world’s most admired AI labs.
In the end, French-Owen’s message is both a reality check and a cautionary tale. While OpenAI remains a beacon for those passionate about AI, it’s also a place of grueling hours, guarded secrets, and a fixation on optics. Behind the innovations and billion-dollar valuations lies a workforce navigating burnout and high expectations.
