OpenAI is testing ads in the free and "Go" tiers of ChatGPT, with ads clearly marked and tailored to user interests. The company claims these ads won't affect chatbot responses and users can opt-out of personalized ads. Competitors like Google and Anthropic have differing approaches to advertising in their AI services.

Anthropic aired four Super Bowl ads that mock OpenAI's ChatGPT for introducing ads to its free tier. In response, OpenAI CEO Sam Altman accused Anthropic of being "dishonest" and "authoritarian," arguing that their portrayal of ChatGPT's ad strategy is misleading. The exchange highlights tensions in the competitive AI chatbot market.
