OpenAI enables in-country inference for GPT-6 Luna in Japan

3 Key Points

  1. What happened

    An OpenAI Japan employee said on November 11 that in-country inference is now available for GPT-6 Luna via the Responses API and Chat Completions API, Standard pay-as-you-go only.

  2. Why it matters

    Processing prompts and answers inside the country gives developers a way to keep inference workloads domestic, a setup the same APIs already offer in some other regions.

WHO IT HITSDevelopers and companies building on OpenAI's API in Japan who need inference handled domestically, particularly those on the Standard pay-as-you-go tier, are the ones affected.

Context & Analysis

OpenAI's API already keeps data for up to 30 days by default for abuse monitoring, even though customer data is not used to train or improve models without explicit consent. Approved users can remove their content from abuse-monitoring logs through MAM (modified abuse monitoring) and ZDR (zero data retention). In some regions, inference processing itself can also stay within the country, and Japan has now been added to that list.

The announcement was made on November 11 by an employee of OpenAI's Japan entity on X. The in-country option is limited in scope: it applies to the Responses API and Chat Completions API, to the gpt-6-luna model, and to the Standard pay-as-you-go service tier only. Those who want to use it need to contact OpenAI and receive MAM and ZDR measures.

GPT-6 Luna is positioned as a lightweight model with strong cost performance in OpenAI's lineup. API pricing is $0.1 per 1M input tokens and $0.5 per 1M output tokens.
