ChatGPT Ads expands to 89 countries as OpenAI details its agent-run ad system

OpenAI expanded ChatGPT advertising to 26 additional countries on October 21, bringing its stated reach to 89 markets worldwide. The company says more than 100,000 advertisers have run campaigns since launch roughly eight months earlier, and that ads remain limited to ChatGPT's Free and Go plans rather than its Plus, Pro or Enterprise subscriptions. The expansion includes additional Latin American markets and countries in Europe, Africa and Asia; businesses can buy through partners or an Ads Manager interface.

In a separate engineering disclosure published the same day, OpenAI described an ad-serving architecture built around a customized language-model orchestrator. That system interprets the user's developing intent, retrieves possible ads, applies targeting and policy checks, and selects candidates for an auction. OpenAI says ad selection runs in a separate service from the model producing ChatGPT's answer, and a response can proceed even if the ads service is slow or unavailable.

The engineering description also distinguishes an auction winner from an advertisement actually displayed: a placement may arrive too late for the current response and never appear. OpenAI presents the separation as a trust safeguard; the company's own description does not by itself constitute an independent examination of every privacy or relevance claim.
