CyberAgent accelerates business with ChatGPT Enterprise and Codex

The Japanese media conglomerate CyberAgent has migrated key business processes to ChatGPT Enterprise and Codex — and now AI operates across three major business verticals: advertising technology, media, and gaming. CyberAgent is one of Japan's largest technology conglomerates. The company owns the Ameba advertising platform, the ABEMA video service, and a gaming division with dozens of mobile titles.

Consolidating such a diverse portfolio of businesses under a single AI solution is a non-trivial task, and it was precisely here that the enterprise version of ChatGPT proved to be the decisive factor. ChatGPT Enterprise provides the company with capabilities that the public version lacks: isolated data storage, department-level access control, and extended usage limits. Codex, meanwhile, handles development — CyberAgent engineers use it to accelerate code writing and review across gaming and advertising products.

According to OpenAI, the implementation has significantly reduced decision-making time and raised quality standards in content production and software development. An important emphasis — on the word "securely." Japanese corporations are traditionally cautious with external cloud services: data localization and corporate compliance requirements here are stricter than in many Western markets.

CyberAgent openly states that enterprise-level confidentiality guarantees became the key condition for scaling, rather than pursuing a limited pilot approach. The CyberAgent case demonstrates a steady trend: large Asian conglomerates are transitioning from AI experiments to systemic implementation. When media, advertising, and gaming operate on a single AI platform, gains in speed and quality become cumulative — each product accelerates the others.

For OpenAI, this is another argument in favor of the enterprise sector as a primary growth driver.
