An engineer's diary reveals the human cost of building OpenAI's next big thing

An OpenAI engineer reveals intense personal sacrifice during Codex's creation.

: Calvin French-Owen, a former top engineer at OpenAI, recounts the extreme effort demanded during a seven-week sprint to develop Codex. This project required working until midnight and resuming early mornings, balancing professional demands with personal life, notably with a newborn at home. These efforts culminated in the intense challenge of deploying the 'monolith,' a complex software piece, which involved high risks similar to renovating an entire skyscraper simultaneously. The strenuous workload paid off as within 53 days of its launch, Codex facilitated over 630,000 pull requests, representing significant automated productivity.

Calvin French-Owen narrates his rigorous journey in building Codex, OpenAI's latest ambitious AI, after joining the company in May 2024. He describes the task as an exhaustive process that obliterated the division between work and personal life, particularly with managing a newborn. Days extended late into the night as the team aimed to reach the public launch in a mere seven weeks from initiating the first line of code. French-Owen refers to this period as the hardest he has worked in nearly a decade.

French-Owen found himself in a challenging environment filled with personal sacrifices to meet the competitive demands in the AI sector. Working with giants like Google and Anthropic meant that the pressure to innovate was significantly high. The team faced numerous hurdles, especially during the last few days leading up to the public launch. On the eve of the launch, they spent the entire night battling a complex technical challenge involving the deployment of the 'monolith.'

Deploying the monolith was akin to renovating an entire building at once, with the risk of the entire system failure if any component malfunctions. The high stakes execution took place with five engineers working until 4 AM, highlighting the extreme dedication required. This hard work culminated in numerous public pull requests soon after the launch, proving the extreme productivity achieved through the Codex AI.

French-Owen does not harbor any resentment towards his time at OpenAI, instead viewing it as an invaluable experience. He describes the opportunity as the 'ride of a lifetime,' emphasizing the collaborative team spirit that helped overcome numerous challenges. This experience reflects the dedication and hard work behind the seamless AI interfaces seen by the public, which are often taken for granted.

The intense work culture underscores the personal sacrifices made by tech professionals to drive innovations in AI. The high intensity demand reflects not only upon the individuals like French-Owen but also upon the broader technological landscape marked by constant competition and urgency. His account is a revealing testimony of the profound human cost behind the cutting-edge developments in artificial intelligence.
