Over 5 million people now use Codex every week, and in Korea that number has jumped nearly 800% since February 1, 2026. That's the context for today's news: Samsung Electronics is putting ChatGPT Enterprise and Codex in front of every employee in Korea and all Device eXperience (DX) staff worldwide.
The Scale Nobody Expected
This is not a pilot or a 500-seat trial. Samsung's deployment covers its entire Korean workforce plus the global DX division - that includes R&D, manufacturing, marketing, corporate functions, and product development. OpenAI calls it one of their largest enterprise launches to date, and for good reason. A company that makes chips, phones, and fridges is betting its entire operational backbone on LLMs and code generation.
Harrison Kim, GM of OpenAI Korea, framed it bluntly: Samsung sees AI not as a tool for specific teams but as a core platform for how employees work and innovate. Codex started as a developer tool, but Samsung is pushing it into non-technical workflows - turning ideas into internal tools, websites, and automated workflows without writing boilerplate.
Why Codex Growth Tells the Real Story
Codex weekly active users in Korea have exploded 800% in just over four months. That's not developers suddenly discovering a new IDE plugin. That's non-technical staff grabbing code generation to automate their own jobs. Samsung's plan to use ChatGPT and Codex across marketing, manufacturing, and corporate functions is a bet that the barrier between "idea" and "working software" is disappearing.
ChatGPT Enterprise brings the compliance layer Samsung's legal and security teams demand: data protection, user management, and governance controls. Meanwhile, Codex handles the execution side. Together, they cover the full spectrum from knowledge work to production code.
The Bigger Picture for Korean Enterprise AI
Seoul National University already gave ChatGPT Edu free to all 47,000 students, faculty, and staff. Kakao integrated ChatGPT into KakaoTalk group chats. LG Electronics, LG Uplus, LG CNS, GS E&C, Samsung SDS, TVING, Krafton, Toss, MUSINSA, Korea Zinc, Nexen Tire, HanaTour, Day1Company, and Worksphere are all using ChatGPT Enterprise, OpenAI APIs, or Codex.
OpenAI's relationship with Samsung started on the infrastructure side - Samsung supplies advanced memory semiconductors for next-gen AI hardware. That deal is now expanding into workforce transformation. When your chip supplier also becomes your biggest enterprise customer, the feedback loop tightens considerably.
