OpenAI unveiled its new flagship AI model GPT-4o today that it says brings GPT-level intelligence to everyone, including free users. The event now raises the stakes for Google’s all-important developers’ event tomorrow, Google I/O, where the tech giant is set to outline its latest advancements in AI.  Google has in the past been relatively slow to roll out its AI features to its wide base of users, so the question hanging over the event tomorrow is whether it will go all-in on gen AI, potentially at the expense of search.
