OpenAI lists in-region inference for GPT-6 Luna in Japan, Australia and India

OpenAI’s platform documentation lists regional processing in Japan, Australia and India. Organisations with active Zero Data Retention can use gpt-6-luna on the Chat Completions and Responses APIs so inference for customer content is performed in the selected region, as well as stored at rest there.

“In Australia, India, and Japan, organizations with active Zero Data Retention can use gpt-6-luna for regional processing.”

The Japan endpoint is jp.api.openai.com. Australia uses au.api.openai.com, and India uses in.api.openai.com. Official docs say these three regions support Standard pay-as-you-go only, that you should use a project in the selected region, and that the two APIs support text and image inputs and text output. Hosted tools aren’t available for regional processing in these regions.

Regional processing in Australia, India and Japan requires active Zero Data Retention. Official docs say Modified Abuse Monitoring alone is insufficient. Image support in these regions requires approval for enhanced Zero Data Retention or enhanced Modified Abuse Monitoring.

To use data residency in any region other than the United States, OpenAI says you must be approved for abuse monitoring controls and execute a Modified Retention amendment. Eligibility for the controls is handled through its sales team. Data residency endpoints are charged a 10% uplift for models released on or after 5 March 2026 that are eligible for data residency.

The docs still distinguish storage from processing. Japan, Australia and India already appear in the table for regional storage across a wider set of services; regional processing is listed only for gpt-6-luna on /v1/chat/completions and /v1/responses. Support for regional storage doesn’t imply support for regional processing. Canada, Singapore, South Korea and the United Kingdom remain listed with regional storage but without regional processing.

Data residency doesn’t apply to system data, which may be processed and stored outside the selected region. Official docs also say it doesn’t cover transmissions caused by an end user’s or customer’s own infrastructure, third-party products offered through the services, or data other than customer content. For Chat Completions, store can’t be set to true in non-US regions.
