Samsung Rolls Out ChatGPT Enterprise and Codex to All Employees in Korea and Global DX Division

Samsung Electronics has signed what OpenAI describes as its largest-ever enterprise contract, deploying ChatGPT Enterprise and Codex to all employees in Korea and the global Device eXperience (DX) division, as part of a broader multi-model AI transformation that also includes Google's Gemini and Anthropic's Claude . This marks a decisive reversal of Samsung's 2023 ban on generative AI tools following a high-profile source code data leak .

Timeline & Scope of the Deployment

The rollout followed a structured timeline over several weeks. On May 26, 2026, Samsung's DX Division announced it would officially introduce external generative AI services, following a two-month pilot with 2,500 employees . On June 9, 2026, Samsung declared a group-wide "AI Transformation (AX)" to reinvent work processes and organizational culture around AI, extending external tools to all affiliates for the first time . The official rollout began on June 12, 2026 in the DX Division, covering finished products such as home appliances, TVs, and smartphones . On June 21–22, 2026, OpenAI and Samsung announced the expanded enterprise agreement: ChatGPT Enterprise and Codex are now available to all Samsung Electronics employees in Korea and all DX employees globally — one of OpenAI's largest enterprise deployments ever .

Reversal of the 2023 Ban

In May 2023, Samsung banned employee use of generative AI tools after engineers in the semiconductor division leaked confidential source code, internal meeting transcripts, and proprietary data by pasting them into ChatGPT on at least three separate occasions . The company responded by blocking all public generative AI tools on company devices and began developing its in-house model, Samsung Gauss . The 2026 rollout re-admits these tools — but now behind a secure enterprise framework with data protection controls .

Employee Use Cases

Samsung plans to deploy ChatGPT Enterprise and Codex across software development, marketing, product development, and manufacturing to enhance productivity and problem-solving . Reported specific uses include:

• Coding and software development — Codex assists engineers with code generation, debugging, and automation .
• Information retrieval and document search — ChatGPT Enterprise serves as an enterprise knowledge assistant .
• Translation, data analysis, and marketing — employees use the tools for cross-language communication, data insights, and campaign planning .
• Manufacturing and R&D — AI is applied across the full operations chain, from research to factory floor .

Multi-Model AI Transformation Strategy

Samsung is pursuing a deliberate "multi-model" strategy rather than betting on a single AI provider :

Model	Provider	Role
ChatGPT Enterprise + Codex	OpenAI	Enterprise productivity, coding, general AI assistant
Gemini Enterprise	Google	Enterprise productivity, Galaxy AI on devices (800M+ units targeted in 2026)
Claude	Anthropic	Enterprise productivity, specialized reasoning
Samsung Gauss	Samsung (in-house)	Internal model — not replaced, but supplemented by external tools

This two-track approach — in-house Gauss plus three external models — allows Samsung to match each tool to the task while avoiding vendor lock-in .

Deepening Samsung-OpenAI Partnership & the Stargate Connection

The enterprise software deal is the second pillar of a broader strategic partnership rooted in hardware. On October 1, 2025, OpenAI CEO Sam Altman signed a letter of intent (LOI) in Seoul with Samsung Electronics, Samsung SDS, Samsung C&T, and Samsung Heavy Industries to supply advanced memory chips — including high-bandwidth memory (HBM) — for OpenAI's Stargate data center initiative, a ~$500 billion AI infrastructure project . The agreement also covers building data centers in South Korea . The June 2026 ChatGPT Enterprise contract extends this relationship from chip supplier to enterprise AI customer, making Samsung both a critical hardware partner and one of OpenAI's largest software deployments .
