ChatGPT ads start today: Here's what to expect - and which AIs don't have them

This article reviews the current and planned use of ads across major AI chatbots: OpenAI is testing ads for Free and Go users in ChatGPT; Anthropic ran Super Bowl ads criticizing in-chat ads and pledges Claude will stay ad-free; Google is expected to bring ads to Gemini and is testing ads in AI Mode; Microsoft Copilot already integrates labeled sponsored content; Perplexity shows sponsored follow-up questions; xAI’s Grok is expected to insert ads in or alongside responses; and Meta AI doesn’t place ads in chats but uses interactions to inform ad targeting across its platforms. Bottom line: Claude is presently the only major chatbot with a public commitment to keep ads out of conversations.
