OpenAI lists in-country GPT-6 Luna processing in Japan

Impress Watch reported on 11 November 2026 that OpenAI began general availability of in-Japan API processing and inference for GPT-6 Luna, covering text and image input and text output. OpenAI's data-controls guide says organizations with active Zero Data Retention can use gpt-6-luna for regional processing in Australia, India, and Japan, on Standard pay-as-you-go, through Chat Completions and Responses. Hosted tools are unavailable there, and Modified Abuse Monitoring alone is not enough. The guide does not date the change. Impress says ChatGPT, Codex, other models, and system data are outside the Japan processing claim.
