Sam Altman, CEO of OpenAI, wrote on X that "I believe that The Wall Street Journal (WSJ) is currently the best newspaper in the United States, but a few hours after we announced the o3 model, they published an article titled 'The Next Great Leap in AI Is Behind Schedule and Crazy Expensive'!?" Prior to this news, OpenAI is currently developing a new generation of reasoning models that will delve deeper into user questions. In terms of naming, they may skip the name "o2" to avoid trademark conflicts with British telecom operator O2 and directly use "o3".
