OpenAI announced U.S. ad tests for ChatGPT Free and Go tiers and launched ChatGPT Go in the U.S.

OpenAI published its advertising principles and said it would begin testing ads in the U.S. for logged-in adults on the Free tier and the $8/month ChatGPT Go plan in the coming weeks. Plus, Pro, Business and Enterprise plans would stay ad-free, and ChatGPT Go became available in the U.S. and everywhere ChatGPT operates.

• Principles: mission alignment, answer independence, conversation privacy and user control.
• Ads would appear at the bottom of responses only when a sponsored product or service is relevant, clearly labeled, and never near sensitive or regulated topics such as politics, health or mental health.
• Users could see why an ad was shown, dismiss it, turn off personalization or clear ad data; conversations would never be sold to advertisers.
