OpenAI Eyes the K-Game Industry, Hosts 'Game Builders Seoul' in Korea

First-Ever Game Development Event Using Codex to Be Held in Seoul
AI Utilization Rate Reaches 70%... Spotlight on Korean Developer Ecosystem

OpenAI, with support from Com2uS, will host a game development event utilizing the coding agent 'Codex.' As the domestic game industry actively incorporates artificial intelligence (AI) into development, OpenAI's move signals its intention to expand the use of coding agents within the Korean developer ecosystem.

On August 5, OpenAI announced that it would hold 'OpenAI Game Builders Seoul' in Seoul on August 31, focusing on game development with Codex. Seoul was chosen as the first host city. Supported by Com2uS, this event will be held under the slogan "Build with Codex, Play with Hive." The event features a track where participants present games developed in advance using Codex, as well as a hackathon in which teams will attempt to create AAA-level games within five hours using the latest version of Codex.

Industry insiders attribute OpenAI's selection of Korea to the strength of the domestic game development ecosystem. One industry official stated, "Korean game developers are quick to embrace new technologies and are highly proactive in applying them to development," adding, "It seems OpenAI also views the Korean developer ecosystem as a symbolic market." The official continued, "The intention is to demonstrate that AI can be leveraged throughout the game development process, and it reflects the judgment that AI's role will expand significantly in the future development of AAA games."

In fact, the game industry is the most active adopter of generative AI among all content sectors in Korea. According to the '2025 Q4 and Annual Content Industry Trend Analysis Report' released this year by the Korea Creative Content Agency, the domestic game industry's generative AI usage rate reached 70 percent last year, the highest among all content industries. AI is being utilized across the entire game development process, from graphics creation for characters and backgrounds, to planning, programming, translation, and quality testing.

Codex is regarded as an AI development partner among Korean game developers. When a developer describes a desired function, Codex drafts code, suggests modifications to fit the existing project structure, or analyzes the cause of errors. The tool assists in swiftly implementing frequently used features, such as player movement, user interfaces (UI), and item systems, and even supports code reviews to further boost development productivity. According to an industry official, "AI is increasingly being used for testing and validation, and is widely adopted in graphics production," adding, "It is mainly used for repetitive tasks such as background and environment design."

On July 20, Song Jae Kyung, a first-generation developer known for leading the development of Nexon's "The Kingdom of the Winds" and NC's "Lineage," unveiled his new title, created with AI, through X (formerly Twitter) and the development platform GitHub. The game is a large-scale multiplayer online (MMO) title in which human participants interact with AI agents.

Oliver Jay, Head of International Business at OpenAI, commented, "Korea is a country with world-class game development capabilities and a creative developer community," adding, "We look forward to sharing experiences and ideas using Codex, and to expanding a new culture of game development in collaboration with AI."
