OpenAI published a technical explainer on ChatGPT's ad stack:
- LLMs parse conversational intent to match relevant ads;
- ads are kept clearly separated from model answers, in both UI and mechanics, to preserve user trust;
- the post covers how relevance is maintained at scale.
It's the technical companion to the ChatGPT Ads expansion to 26 new countries with 100,000+ advertisers.
