Samsung Electronics is rolling out ChatGPT Enterprise and Codex to all employees in Korea and its global Device eXperience division, reversing a 2023 ban after building strict security controls.
OpenAI has announced that Samsung Electronics is deploying ChatGPT Enterprise and Codex to all employees in South Korea and to staff in its global Device eXperience (DX) division — covering smartphones, TVs, appliances, and other consumer electronics. OpenAI describes the rollout, announced on June 21, 2026, as one of its largest enterprise deployments to date.
The move completes a sharp reversal from March 2023, when Samsung banned generative AI after engineers leaked proprietary code through the public ChatGPT app. Samsung now grants access only to staff who complete internal AI security training, following a two-month proof-of-concept in which 2,500 DX employees tested ChatGPT alongside Gemini and Claude. Weekly active Codex users in Korea grew nearly 800% between February 1 and the rollout date. Samsung SDS also became the first Korean entity authorized to resell and manage ChatGPT Enterprise for other businesses, with full workforce training targeted by the end of 2026.

Samsung deploys ChatGPT Enterprise and Codex globally in one of OpenAI's largest enterprise rollouts to date. Korea-based staff and teams across the Device eXperience division now share the same AI stack for research, specs, and embedded software — a sharp contrast to the company's brief 2023 ban. Samsung says internal security reviews, data boundaries, and usage policies were prerequisites before the global rollout could proceed.
