OpenAI adds GPT-6 Luna API processing in Japan

Nov 11, 2026
OpenAI now lets approved API customers process GPT-6 Luna requests and inference in Japan, subject to Zero Data Retention requirements.

OpenAI now lets approved customers process GPT-6 Luna API requests and model inference in Japan, according to a report from BigGo Finance. The option is generally available for text and image inputs with text output.

Customers must receive prior approval for Zero Data Retention and enable it in a new API project configured for storage and processing in Japan. The option supports the Responses API and Chat Completions API under Standard pay as you go billing.

The regional controls apply to specified customer content. They do not cover account, usage, or billing data, processing by external services, ChatGPT, Codex, other models, audio, image generation, or tools hosted by OpenAI.

The change builds on the data residency option OpenAI introduced in Asia, including Japan, in May 2025, which kept stored customer data in the country. According to the report, OpenAI plans similar in-country processing for Australia and India.
