Samsung Electronics has rolled out ChatGPT Enterprise and Codex across its global workforce, marking one of the largest enterprise AI deployments OpenAI has signed with any company worldwide. The rollout, announced on June 22, covers all Samsung Electronics employees in South Korea and all staff in the company’s Device eXperience (DX) division globally.
This deployment represents a significant reversal for Samsung, which banned generative AI tools in 2023 after proprietary code was inadvertently leaked through ChatGPT. The company began revising its AI stance in late 2025, signing a reseller partnership with OpenAI to facilitate ChatGPT Enterprise deployments for both internal staff and as the first Korean entity authorized to offer the service to external businesses.
Employees will utilize ChatGPT Enterprise for knowledge-based tasks including information search, document drafting, idea generation, and data interpretation, all within the company’s security policies. Codex, OpenAI’s AI coding assistant, will assist both developers and non-technical staff in creating software, internal tools, websites, and automated workflows.
The ChatGPT Enterprise rollout is part of Samsung’s broader “AX” — AI transformation — initiative introduced in early June. Alongside this, the DX division began operations of three external generative AI services on June 12: OpenAI’s ChatGPT, Google’s Gemini Enterprise, and Anthropic’s Claude. The Device Solutions semiconductor division, previously utilizing Claude, also opened access to ChatGPT on the same date, with Gemini scheduled for release later this year.
OpenAI reported that over 5 million people now use Codex weekly in various roles, with a nearly 800 percent increase in weekly active users in South Korea since February 1, 2026.
This enterprise software deal builds on a strategic partnership initiated in September 2025, when Samsung Electronics Chairman Lee Jae-yong and OpenAI CEO Sam Altman signed a letter of intent covering advanced memory chip supply for OpenAI’s Stargate data center initiative. At that time, Samsung was already exploring broader adoption of ChatGPT to facilitate AI transformation within the company.
