OpenAI Tests Exclusion Targeting for ChatGPT Ads
OpenAI is testing exclusion (negative) targeting guidance for its ChatGPT Ads system with a small group of advertisers, a feature confirmed to Adweek by spokesperson Taya Christianson. The option would let advertisers indicate chat contexts where they do not want their ads to appear; it is still in development and no rollout date has been announced. ChatGPT Ads, which launched in February 2026 and expanded to Germany and 30 additional markets on August 24, 2026, display beneath model answers and include image creative, advertiser name, favicon, title, description, and a landing page. Some ad buyers and an AI visibility provider have raised concerns about explaining target audiences to ChatGPT, limited placement controls, and poor visibility into where ads run. OpenAI reports over 900 million weekly users, many on free tiers where ads appear.

Redefining UX Processes for the Age of AI
A Medium opinion piece by Patrick Neeman argues that modern UX inherited the rituals and business model of mid‑century advertising agencies — the pitch, the account model, the auteur — and that those habits now undermine outcome‑focused product work in an era where AI changes the cost and nature of execution. The author calls for a reset toward systems, continuous discovery, measurable business outcomes, collaboration over star designers, and loyalty to users rather than the loudest stakeholder. The article cites industry thinkers and research (e.g., McKinsey) to support a shift from deliverables and shows to durable systems and iterative user‑centered measurement.
