.codex Domain Information

The .codex domain extension is a closed namespace for information, products, services, and operations tied to the Codex brand from OpenAI. A brand-controlled namespace helps people tell authorized Codex properties from imitations, which protects the trust Codex has built. The applicant is OpenAI OpCo, LLC.

Addresses ending in this extension are used for sites and services that support Codex and related offerings. Expected uses include product information, developer resources, customer support, and access points to products or services. Because the namespace is tightly controlled, visitors can recognize official Codex properties and avoid look-alike addresses. Its worth to OpenAI comes from that consistency and protection, not from registration volume, and the specific uses can change over time while staying tied to Codex.
