OpenAI has discontinued promotional messages in ChatGPT after user backlash, with chief research officer Mark Chen admitting the company "fell short." Users reported irrelevant ads for Peloton and Target in conversations unrelated to those topics. With only 5% of ChatGPT’s 800 million users paying for the service, OpenAI faces a $115 billion burn rate through 2029 while pursuing a $1 trillion AI infrastructure goal. The incident highlights the challenge of monetizing AI without alienating users, as OpenAI searches for more acceptable revenue streams.
